ASP. NET exception: "The expression value cannot be calculated because the code has been optimized or the local framework is located on the call stack." SOLUTION

Today, the project encountered an exception that we have never seen before.CodeI have been optimized or the local framework is located on the call stack and cannot calculate the expression value. "I checked the information and found that this exception was due to the use of" response. end. The solution is as follows:

Exception: The expression value cannot be calculated because the code has been optimized or the local framework is located on the call stack.

Cause:

If you use the response. End, response. Redirect, or server. transfer method, a threadabortexception exception occurs. You can use the try-catch statement to catch this exception.
The response. End method terminates the execution of the page and switches the execution to the application.ProgramApplication_endrequest event in the event pipeline. Do not execute the code line after response. End.
This problem occurs in the response. Redirect and server. transfer methods, because both methods are called internally.Response. End.
Solution:
To solve this problem, use one of the following methods:
• For response. End, call httpcontext. Current. applicationinstance. completerequest instead of response. End to skip the code execution of the application_endrequest event.
•For response. Redirect, use the overload response. Redirect (string URL, bool endresponse). This overload will pass false to the endresponse parameter to cancel internal calls to response. End. For example:
Response. Redirect ("nextpage. aspx", false );
