"ASP. shorttopmodules_flashimageshow_editflashimagerotator_ascx.frameworkinitialize ()": no suitable method is found for rewriting.

This error was found when I wrote the dnn module today.
Error cs0115:
"ASP. shorttopmodules_flashimageshow_editflashimagerotator_ascx.frameworkinitialize ()": no suitable method is found for rewriting.
It turns out to be a spelling mistake. The inherits = "myclass" in my ascx file is different from the myclass name in the CS file. In ascx, I wrote "myclass ".

However, if you make this error in dnn, the error message does not contain this error message due to the error handling mechanism of dnn.
So I can find the answer. Dnn debugging tool dnndebug. aspx-how to debug program errors with unspecified error information
