Question

The ReportInfo is a structure. The structure works fine on one web page but I am trying to use it on another web-page. Here is where I saved the ReportInfo structure to the Session Variable

Session[“ReportInfo”] = reportInfo;

On the other web-page, I re-created the Structure and then assign the session variable to it, like this…

reportInfo = (ReportInfo)(Session[“ReportInfo”]);

I get the following run-time error:

System.InvalidCastException was unhandled by user code
Message=”Specified cast is not valid.”
Source=”App_Web_-s8b_dtf”

How do I get the ReportInfo structure out of the Session variable to use again?

Answer 1

Have you checked the value of Session["ReportInfo"]? Perhaps it’s null or some other unsavory value? Also, I assume reportInfo in the second page is of type ReportInfo?
