I am trying to access开发者_运维百科 the Session variable in Asp.Net ashx handler as shown below.
public void ProcessRequest (HttpContext context) {
context.Session["VariableName"] = Id;
}
But the context.Session is always Null inside the above method. How do I access Session objects in ashx file?
You have to "implement" either IRequiresSessionState or IReadOnlySessionState, with former providing full access to session, and the latter providing read-only access.
I'm quoting "implement" here because these two are so-called "marker interfaces", which means they have no members.
In VB, implement the interfaces mentioned by Anton (IRequiresSessionState or IReadOnlySessionState) like this:
Public Class MyAshxFile
Implements System.Web.IHttpHandler
Implements System.Web.SessionState.IRequiresSessionState ''need this for session variables
Implements System.Web.SessionState.IReadOnlySessionState ''need this for session variables
