Asp. NET in the general handler in the use of Session simple introduction _ Practical skills

Copy Code code as follows:

<%@ WebHandler language= "C #" class= "Changepwd"%>

Using System;
Using System.Web;
Using System.Web.SessionState;
public class Changepwd:ihttphandler, ireadonlysessionstate
{

public void ProcessRequest (HttpContext context)

{
Context. Response.ContentType = "Text/plain";
Operuser ou = new Operuser ();
if (OU. Changewspassword (context. session["Ws_user"]. ToString (), context. request.querystring["PWD"]. ToString ()))
{
Context. Response.Write ("true");
}
Else
{
Context. Response.Write ("Flase");
}

}

public bool IsReusable {
get {
return false;
}
}

}

Plus using System.Web.SessionState; and ireadonlysessionstate

If your handler accesses the session state value, it must implement the IRequiresSessionState interface, which does not contain a markup interface for any method.


Import using System.Web.SessionState;
Sure enough, just add a irequiressessionstate tag interface to your custom class, and you don't need to implement any methods.
With this, there is also another interface: The Ireadonlysessionstate interface, which indicates the HTTP handler, has read-only access to the session, and is an empty interface, without implementing any methods.
