Is it safe to access asp.net session variables through static properties of a static object?Here is what I mean:
public static class SessionHelper
{
public static int Age
{
get
{

Is it possible that userA could access userB's session data this way?

this is the stack trace error I am getting. At this point, I'm a little clueless how to resolve it.

I've set up a strongly-typed View and a controller method to save the object represented in that View. The object in question is from a class that uses named parameters with default values. This is not a database object, but rather is the intermediate object that is used for the display and user input. It gets translated into a database object in the service class. Anyway, when I attempt to save the object, I get the following error:
System.MissingMethodException: No parameterless constructor defined for this object.
This is kind of aggravating. I can add a parameterless constructor to the class, and then everything works just fine. I just don't understand why it is necessary. I'm new to named parameters with default values, but the reading and such that I've done has described that method calls with default values do not have to have a 'no-parameter' implementation. You can just call the method with any or none of the parameters specified and everything works as expected. If there is a 'no-parameter' implementation and no params are passed, then that one is used, since it is more specific than the one with default values. Is the behavior somehow different when this is used in the constructor of a class? Why would I have to include a parameterless constructor when I have all the values accounted for? Is the runtime creating an object on the fly as the save method executes, which requires this? The method is like this:
[Code]....
I'm wondering if the object is instantiated by the runtime in order to populate the method parameter, and then assigned values from the form collection. I suppose that would make sense, but I do not understand why this causes an exception. For what reason would a parameterless constructor be required?

Does anyone have any good examples of how to make Unity 1.2 or 2.0 work with ASP.NET WebForms?
I thought I had this figured out, but evidently I'm missing something. Now I'm getting the error; "No parameterless constructor defined for this object". I remember getting this error a couple years ago, I and just don't remember what I did.
Obviously Unity isn't working as it should because somewhere along the way I've forgotten something.
Here's some of my code:

From client side, I need to call a server method that is not static. For example, I got the following user control ucData (private instance of code-behind) that is Databind in the load event. The server method I need should return ucData.IsValid(). So it can't be static

I am creating a static variable and adding to session.This variable has value that is user specific. Now I am getting a problem with this users are complaining that they are getting values that should be another users. It's like a mix up with session. Could this be because of static variable declaration?

I am using jQuery to call PageMethods. For certain operations, the current user credentials must be validated and for other operations, I need to call other static methods. Here is some sample code:
Sample #1
[WebMethod]
public static void PostComment(string comment)
{
UserAuth auth = new UserAuth();
if (auth.isAuthenticated)
{
//Post comment here...
}
}
Sample #2
[WebMethod]
public static string GetComment(int commentId)
{
commentDto comment = //get comment data from the database...
string friendlyDate = ConvertFriendlyDate(comment.commentDate);
return friendlyDate + " " + comment.text;
}
public static string ConvertFriendlyDate(DateTime commentDate)
{
string friendlyDate = //call static utility method to convert date to friendly format
return friendlyDate;
}
Will I be safe using these kinds of operations? Am I better to drop page methods and just call a separate ASPX page for my AJAX requests?

I hate to see the name of the class used as a string parameter like "FileDownloader" in the code, and I would like to use something like this FileDownloader.Name(), where FileDownloader is name of the class.
Only problem is that I can't find out how to do that without instantiating object or creating a static method...
Is there a way to get a class name in .net without having the object instance and without creating a static method that returns the name of the class?

We have a Static class that 's called CData in our asp.net c# app.It handles all the data layer CRUD functionality on our pages.
Problem is, were are losing the intellisense reference in our pages to it.For example: we would expect to type CData.(dot) and have a list of methods and properties available to us.
Nope. Not there.
I kind of thought it was because the file was getting too long at 3000 lines of code, since some other static classes were working ok.
So then I thought that I'd try wrapping the CData Class in a namespace. That worked, but of course I had to put an include statement of the top of each page that's using CDATA, also, now some of the other developers are getting errors in there pages complaining about missing methods that are in CDATA, but their pages are not seeing.
