Sam Hobbs · Answer

An UnhandledException means that the exception was not handled; that there was not a single try/catch that could be used. So please read the documentation that Karthik provided. Also look for articles in this web site about exception handling. Also read the MSDN articles about exception handling. If you understand how exception handling works then you will easily understand how to prevent the UnhandledException exceptions.

It's not possible (or even desirable) to prevent an application from exiting when certain 'fatal' exceptions occur. You can usually log them and possibly take some remedial action enabling a more graceful exit but that's all. If an exception has corrupted the state of an application, then it wouldn't be a good idea to try and recover from it in any case.

Karthik, i have use try...catch...But my application still crash. In the event AppDomain.CurrentDomain.UnhandledException i can write log, but the application exits anyway.

Karthik Agarwal · Answer

in general try and catch block should solve the problem. But if you are a fresher to .Net sometimes you can't except when exception may occur. If you can expect when the exception can cause you can avoid the application from crashing.
