C # How to capture unhandled exceptions

There are always some exceptions that we could not expect when writing code. What we need to do is to record them.

The following is a sample code:

// Catch the current unbound exception

AppDomain. CurrentDomain. UnhandledException + = new UnhandledExceptionEventHandler (CurrentDomain_UnhandledException );

// Capture thread exceptions

Application. ThreadException + = new ThreadExceptionEventHandler (Application_ThreadException );

Static void Application_ThreadException (object sender, ThreadExceptionEventArgs e)

{

Exception exp = e. Exception;

// Todo: The record is abnormal.

}
Static void CurrentDomain_UnhandledException (object sender, UnhandledExceptionEventArgs e)

{

Exception exp = (Exception) e. ExceptionObject;

// Todo: The record is abnormal.

}

It should be noted that the exception will be thrown, and the program will crash.
