How to assign value to a static variable in a non-static function?

Question

Basically, ajax in aspx is polling the value return from .cs every 1000 ms from a WebMethod in .cs which is static GetData(). A property i

Answer 1

Prefix your call to the static method with the class name.

Downloader.PERCENT = library.returnValue();

However as John points out, unless you can guarantee that you would only have one concurrent user for your application, then you shouldn't be using a static member for this task.

A better approach might be to store your PERCENT data in a session variable. That way it's only scoped per session, and not for the entire application.

Session["Percent"] = library.returnValue();

Then change your webmethod like this:

[WebMethod]
public static string GetData()
{
     return (string)Session["Percent"];
}
