C# - Creating XMLSerializer In .net Throws Exception
Jul 22, 2010
We have an old asp application that instantiates a .NET com visible class. In this class, we do some serialization to store our object in the session.
When I call the following line of code in my test class, it works fine.
var cereal = new XmlSerializer(couponApplicator.GetType());
However, when it gets called in the website and I am debugging, it throws the following error:
{"Cannot execute a program. The command being executed was "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\csc.exe" /noconfig /fullpaths @"C:\WINDOWS\TEMP\rwot-yx9.cmdline"."} System.SystemException {System.Runtime.InteropServices.ExternalException}
I thought maybe it was permissions related so I tried giving 'EVERYONE' full control to the windows/microsoft.net folder as well as the windows/temp folder. For reference, I am running this on a Windows XP machine.

I have simple 3 tier web application and have mostly CRUDE functionalities. Recently I required to add new console application to the existing solution in which I call data layer methods for retrieving data from DB but I get an exception "The type initializer for threw an exception."When I debugged I found that the exception is thrown at datalayer on first line of class where I get connectionstring from
web.config, the code is public static readonly string CONNECT_STRING =
ConfigurationManager.ConnectionStrings["DbConnectString"].ConnectionString;
Now if I hardcode the connection string value like public static readonly string CONNECT_STRING = "Data Source=XYZ;uid=sa;password=XXX;initial catalog=ABC;"
it works fine.I don't understand what is the issue here as web application works fine with this datalayer.

every now and then my server throws an exceeption. When it first starts to throw an exception the server wont work until I reinstall my web app (copy and Paste). I think this forces a restart of IIS and somethiong gets cleared bercause the app is working again for some hours, sometime less. Now I have created a scheduled task recopying all the web site files every 15 minutes. This restarts the server and the users are able to use the site. Problem is that now the server either start throwing exceptions, or the user is kicked because the server restarts. So you see, this is absolutly not a good solution.I have looked in the Event Viewer on the sever. Her is some examples of the exceptions:
[Code]....
An other exception:
[Code]....
As you can see, the common part of all the exceptions is the Exception message: Unable to cast object of type 'System.Int32' to type 'System.String'. Her is the code of one of the places throwing an exxception:

i have this (simple) code
<% Html.RenderAction("Version", "Generic"); %>
in my masterpage of my asp.net mvc 2 app. This method returns the version of the application.
i also have this code in my controller:
class GenericController : BaseController
{
[ChildActionOnly]
public string Version()
{
try
{
string assemblyFile = Assembly.GetCallingAssembly().FullName;
FileInfo fi = new FileInfo(assemblyFile);
string version = fi.LastWriteTime.Year.ToString( ) + fi.LastWriteTime.Month.ToString() + fi.LastWriteTime.Day.ToString();
return version;
}
catch (Exception e)
{
return "1.0";
}
}
}
Now i get this error:
Execution of the child request failed. Please examine the InnerException for more information.
and the innerexcpetion is:
{"The controller for path '/Account/LogOn' was not found or does not implement IController."}
What i was thinking is that maybe the code can't execute because the user is not logged on yet, and tries to redirect to the logon method etc.
So the first thing i was thinking is to grant access in the web.config (like i do with the directory that has the css and images in it, it should also be accessable when you're not logged on:
<location path="Content">
<system.web>
<authorization>
<allow users="*" />
</authorization>
</system.web>
</location>
but what is the path for this (version) method ?
(or maybe there is another reason for the excpetion.

After googling for couple of days, I really cannot solve described issue. Hope here will find a solution
I'm using attached code when calling WCF service on the same server. I get Timeout error randomly in call WebReq.GetRequestStream()
When I'm check netstat I see that connection remains open, so probably is there a problem, but I don't know how to solve it
//request inicialization
HttpWebRequest WebReq = (HttpWebRequest)WebRequest.Create(url);
WebReq.Method = "POST";
WebReq.ContentType = "application/json; charset=utf-8";
WebReq.ContentLength = buffer.Length;
WebReq.Proxy = null;
WebReq.KeepAlive = false; //also tried with true
WebReq.AllowWriteStreamBuffering = false; //also tried with true
//this produces an error
using (Stream PostData = WebReq.GetRequestStream())
{
PostData.Write(buffer, 0, buffer.Length);
PostData.Close();
}
//open and read response
HttpWebResponse WebResp = (HttpWebResponse)WebReq.GetResponse();
Stream Answer = WebResp.GetResponseStream();
StreamReader _Answer = new StreamReader(Answer);
WebResp.Close();
//return string
return _Answer.ReadToEnd();
Timeout is thrown mostly after some 10 seconds of idle time, but also after five or so requests in the row. Really cannot find a pattern.
What could be wrong with this code? Is there any other (better) way for calling WCF service?

I have a custom authorization attribute, that basically check if the current user's role is equals to the current area name, and if not, redirect them to the signup view in that requested area. (dummy role provider at this this stage, therefor check it against the user's name at the moment)
It runs fine (IIS) but when I debug it I can see a Security Exception are being thrown by the code

I have several text boxes in an asp:Panel. When the user hits Enter from any of those boxes, I want the form to submit as if they've clicked btnAddTag. (When the cursor is not in those boxes, I have a different default submit button.)
The aspx:
<asp:Panel id="thePanel" runat="server">
<asp:Button ID="btnAddTag" Text="Add Tag" runat="server" />
</asp:Panel>
The vb:
tagPanel.DefaultButton = btnAddTag.UniqueID
The exception:
The DefaultButton of 'tagPanel' must be the ID of a control of type IButtonControl.
The value of btnAddTag.UniqueID is ctl00$phMain$btnAddTag (there's a master page, this section is called phMain).
I've also tried CType(tagPanel.FindControl("btnAddTag"), Button).UniqueID.

In Asp.net application. i cache a Linq to Xml result to a Cache object. when i cast the cache object back to generic list. i get the following exception.
[A]System.Collections.Generic.List`1[CarRentalAddress] cannot be cast to [B]System.Collections.Generic.List`1[CarRentalAddress]. Type A originates from 'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' in the context 'LoadNeither' at location 'C:WINDOWSassemblyGAC_32mscorlib2.0.0.0__b77a5c561934e089mscorlib.dll'.

My code looks like this.
if (!Page.IsPostBack) { if (Cache["xml"] == null) { DataSet ds = new DataSet(); ds.ReadXml(HttpContext.Current.Server.MapPath("~/CarRentalAddress.xml")); var grid = (from d in ds.Tables[0].AsEnumerable() orderby d.Field<string>("City") where d.Field<string>("Enabled") == "1" select new CarRentalAddress { City = d.Field<string>("City"), HotelName = d.Field<string>("HotelName"), Address = d.Field<string>("Address"), EmailID1 = d.Field<string>("EmailID1"), EmailID2 = d.Field<string>("EmailID2") }).ToList(); Cache["xml"] = grid; totalrows = grid.Count().ToString(); grdAddress.DataSource = grid; grdAddress.DataBind(); } else { //Exception is thrown by this line var grid = (List<CarRentalAddress>)Cache["xml"]; totalrows = grid.Count().ToString(); grdAddress.DataSource = grid; grdAddress.DataBind(); } }

I am working on application which is deployed in UK environment. But the machine which I am using has US as dateculture.
I always face issues while running application on my machine as some of the functionality which involves date doesnot work and throws exception.
I tried to google on the datetime conversion issue but it did not help.
Can any one please guide me about the changes to be done so that the application works fine in both US and UK environments?

This problem is trivial to duplicate. Do any query on a table which contains a timestamp / rowversion column. Set a breakpoint and examine the resulting query in the Linq to SQL visualizer. Click on Execute which displays the results in a DataGridView. For each row you get "System Argument Exception: Parameter is not valid" when it tries to display the timestamp / rowversion in the grid. What is most annoying is that there is no way to get out of the visualizer without going to Task Manager and killing the Visual Studio process, devenv.exe.
This is definitely a bug. How can you presume to be able to display a database query when you can't display an essential datatype like timestamp / rowversion? Is there any way around this ? I would like to add that in general the CLR is woefully inadequate in the way it handles timestamp / rowversion fields. It would be nice if they could be defined, copied, compared, displayed and serialized in some standardized automatic way.

AjaxControlToolkit.ToolKitScriptManager.OnInit() throws thread abort exception for every aspx page. I have an asp.net 2.0 Ajax application, where I have set the following properties of ToolScriptManager on my pages.
<ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server" EnableScriptGlobalization="true"
EnableScriptLocalization="true" CombineScripts="true" EnablePageMethods="true">
<Scripts>
I have this configuration on all the aspx pages in my application. When I checked the .NET CLR exception Performance counter I figured out a large number of exceptions, mainly one exception per page load is occuring. On running windbg I was noticed that
AjaxControlToolkit.ToolKitScriptManager.OnInit() has the following code block which is getting executed. The OutputCombinedScriptFile() returns true. But since I am setting my controls on DesignTime still designmode is set to false for toolkitscriptmanager.
if (!DesignMode && (null != Context) && OutputCombinedScriptFile(Context))
{
// This was a combined script request that was satisfied; end all processing now
Page.Response.End();
}
I am not sure if this is a reported bug or even a bug with ajax, but this is causing havoc in my load test results as I have around 3 hundred thousand HTTP requests to be handled per day out of which 80% are aspx page requests resulting in a large number of threadafbortexceptions, thus affecting the performance.

I have implemented the following functionality that connects to webservice and downloads a favicon from a given site and saves it to a byte[] which I store in our database. I now want to set it up so that it saves the icon to the disk. However I am getting a "Parameter is not valid" when I try and create the image from the byte[].My code is as follows..
stream.Write(imageByteArray, 0, imageByteArray.Length);
Image i = Image.FromStream(stream); // EXCEPTION HAPPENS HERE.
i.Save(@"C: mp" + filename + ".ico");
The exception occurs on the middle line. This code works perfectly 9 times out of ten, but for some favicons, even thought the icon is a valid image (or at least it appears to be and it shows in the browser when point at it) I get this exception. Does anyone have any ideas? I am pulling my hair out here!

I am working on a 3-tier asp.net application. Currently I'm stuck up in a situation where I need to handle a specific type of exception (User Defined) in DAL and Show alert to the user if that exception occurs in DAL.
I tried following things:
1) I raised that exception from the DAL and catch it in BLL and throw a new BLL exception to for that DAL exception and finally catch it in the UI layer to show the alert to the user. I've successfully implement this in my project. But there are some issues in this approach. First of all I feel this is not right way to do this as it may lead to performance related issues. Secondly, the application contains more than 500 pages and classes. so I need to attach additional catch block in every method to catch the BLL exception. which is the last option i'd like to take.
2) in second approach I logged the the DAL exception into a text file. but problem in this approach is that how could the UI layer know that exception has occurred and show the alert to the user. Is there any event in asp.net where i could handle all this activities?
my question is what is the best approach to handle this type of situation? Will Exception handling block help me in this?
I've tried reading many articles on this but i couldn't get an answer for my question? I might not be using right keywords for my search.

i have this application structure:
1. Presentation Layer which calls
2. Business Logic Layer which in turn calls
3. Data Access Layer to do the dealing with the database.
Now i have a Contacts page from where i can add a new contact to the database.So to add a New Contact i fill in all the required details and then call a Add Method (residing in the BLL) from the page, which in turn call a Add Method residing in the DAL.this method in the DAL returns the Current Identity of the record which is then return back to the BLL method and finally delivered on the page.this is fine. but what if a get an exception how do i handle it properly because the method in DAL has a return type of int and i dont want to throw another error!! coz other wise i will have to write try catch in almost all the methods.
//something like this
public int AddMethod(ContactClass contactObj)
{
int result = 0;[code]...
rather i want to show the user a user-friendly message which they can easily understand and in the mean while i will send a mail to myself documenting the Error that just occurred.how can i implement my custom exception classes.
