ashx

问题 I have an ASP.net C# 4.0 website project. I am calling an ASHX handler using a jQuery AJAX postback.

No symbols have been loaded for this document." Sure enough, when I run the AJAX call to the handler, the breakpoint is not hit.

问题 This question is a following from another question I asked - Passing client data to server to create Excel or CSV File.

问题 I have a ashx file in a non web project in VS2008. The type of web project (stsdev that is used with Share Point) deploys the ashx file to the server. I can navigate to the file and it is there. In VS2008 when I try and put a break point in the ashx code it will not let me. This means when I connect to the WP3.exe process to remotely debug it nothing will be fired. What steps can I take to get this to debug? 回答1: The link here covers it well: http://www.myrocode.com/post/2009/06/03/Custom

问题 I'm using an ASHX handler, i want the handler to check if Session != null. if (context.Session["Username"] != null) And i get this error pointing this line: System.NullReferenceException: Object reference not set to an instance of an object. What's the problem? 回答1: if (context.Session["Username"] != null) Does your handler implement IRequiresSessionState? Otherwise Session might not be available.
