C# - How To Handle The Hashtable Null Value
Aug 12, 2010
I have a problem while checking a hashtable value. In the code below I am storing 60 values in the hashtable "hash". One of the values is (or can be) Null. I am checking each entry against its corresponding entry in hashtable "hash1", to see if they match each other. If they don't match I want to check if the value in "hash" is Null, but I can't catch it - it's falling through the 'else' part). How can I overcome this problem?

What if a user hits my site with [URL]t rather than [URL] In other words, they do not specify a value for {id}. If they do not, I want to display a nice "Not Found" page, since they did not give an ID.Is there a more standard MVC framework way of handling this, rather than the code I presently use (see below), where I test accept a nullable int? and then for null? Surely there is a smoother way to handle this.

I have asp.net form with C#, where is I am taking user information to insert in the database as usual by using Linq. well. Where as I am taking Date of birth also from the user, but if user skip to fill date text box from ui, then I am getting date like '01/01/0001' something like this, which certainly database security would not allow to store it.
So I need to check somewhere in my code that it is null or in this (above given) format. If it is null or in format '01/01/0001' then what exactly I have to do? I don't have any default
value for dates.
So what is the standard way to handle if date is null (but not mandatory). So many times I found myself in trap while handling null for various types.

I need to retrive a value from a column of a table per stored proc. This is usually an integer, but also can be null. I get this value and store it in a session variable.
Later, I need to pass this same session variable to another stored proc.
Session["myVariable"] = ds.tables[0].rows[0][1]; // this can be null or an integer
somewhere else in the project, I need to pass it to another stored proc exactly as received.

Given the following simplified code block in ASP.NET
<% foreach( item in Model) { %>
<%=item.OriginalText.OriginalText1 %>
<%} %>
OriginalText is a class which may be null. I am looking for a simple (clean) way to check for this null and return an empty string ("") instead.

I get a recordset returned from DB and try to load it. However sometimes field "LastRun" may be empty (NULL). when i have this it compiles fine but errors out when value is null m_LastRun = Convert.ToDateTime(r["LastRun"]); when I take out Convert.ToDateTime it doesn't even compile.

I'm using a custom ashx HttpHandler to retrieve gif images from a database and show it on a website - when the image exists, it works great.
However, there are cases when the image will not exist, and I'd like to have the html table holding the image to become invisible so the "image not found" icon is not shown.

I have a class with properties for stuff like FileNumber, OpenedDate, ClosedDate etc.When I Initialise the class I set the datetime variables to Date.MinValue.Then when I populate my textboxes I check if the value of the date variables are Date.Minvalue and I set the textbox text to an empty string.
Code:
If(File.OpenedDate = Date.MinValue, String.Empty, File.OpenedDate.ToString("yyyy/MM/dd"))
However whe I try to save the data to my sql server db I get a datetime out of range error. What is the correct way to handle these null values in my date columns?

I am converting my datatable to LISt using LINQ how do I handle nulls coming from database
List<Port> portDetails = new List<Port>();
DataTable dt = ds.Tables[0];
portDetails = (from q in dt.AsEnumerable()
select new Port
{
PortCode = q.Field<string>("Code"),
ExtCode = q.Field<string>("Nb"),
Name = q.Field<string>("Name"))
}).ToList();
In the above query if Code is null I do not want property portcode to be set to the value it should only set if it is not null or not blank
PortCode = q.Field<string>("Code"),

I am using the DetailsView Control to read a LastUpdatedDate field (which can be null until an update is performed) from the database. The LastUpdatedDate is of type DateTime saved in UTC. With the DetailsView control, I can use the NullDisplayText property of the boundfield to safely display an custom message. However, once converted to a template field, that property is lost. Now, how would I display that message if the field is null as I am also formatting the date for display to show in local time.

I've got a detailsview control on a page. The table that it interacts with has a DateTime column in it. This column is nullable, and a lot of the records have null for that value. In the EditItemTemplate I've got a calendar control. When I try to put the DetailsView into edit mode, I get the following error message:
System.InvalidCastException was unhandled by user code
Message=Specified cast is not valid.
Source=App_Web_srpmlyjd
StackTrace:
at ASP.entries_aspx.__DataBinding__control44(Object sender, EventArgs e) in c:inetpubwwwrootMediaLibraryEntries.aspx:line 103
at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding)
at System.Web.UI.Control.DataBindChildren()
I am convinced that the problem is the null values in the DateTime column of the table. I've done some web searches on this, and some have suggested placing some dummy values into that column, but that seems more like a kludge, rather than a solution. How do I keep nulls in the table, and yet not have that preceeding error come up when a user tries to edit the selected record?

I am building a Asp.net Application. I need to save a HashTable in a session.
At page load i am writing
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
Session["AttemptCount"]=new Hashtable(); //Because of this line.
}
}
Here problem is, when a user refresh the page, session["AttemptCount"] also get refreshed.
I want to know where should I declare
Session["AttemptCount"]=new Hashtable();
So that my seesion do not get refeshed.
EDIT In Global.asax, this session will get started, as soon as user opens the website. I want to creat this session only if user go to a particular page. i.e Login.aspx

reasking some basics to clear out from this messed up things
1) difference between using normal array & using hashtable in terms of storage, access speed
2) is it possible to store values from serverside controls in javascript on client side in a normal array variable ( values can be of different types) even on postback??.
if yes how
3) currently i have hidden fields which stores values on client side and on postback saves in hashtable ie saving data on server & not on client.

1) As per my understanding, Session variables like HashTable and another variable in Session must be initialized. The best place as per my knowledge is Sesson_Start Event. But at some post its written that we must do that in Application_Start. I think it is not true, as that could lead to problems with different user sessions. Reference is this [URL] Let me know about the concept.
2) Storing variables like string, boolean and etc in Session is slower than storing objects in Session like HashTable, Arrays etc.. becuase they dont require boxing and unboxing. Is that true? Reference. [URL]
