ErrorEventArgs contains the Exception that caused the FileSystemWatcher::Error event. This class provides the GetException method to retrieve the exception.

The following example creates a new instance of ErrorEventArgs and initializes it with an Exception. Then the example calls GetException to retrieve the Exception and display the error message. There is no form associated with this code.

int main()
{

   // Creates an exception with an error message.
   Exception^ myException = gcnew Exception( "This is an exception test" );

   // Creates an ErrorEventArgs with the exception.
   ErrorEventArgs^ myErrorEventArgs = gcnew ErrorEventArgs( myException );

   // Extracts the exception from the ErrorEventArgs and display it.
   Exception^ myReturnedException = myErrorEventArgs->GetException();
   MessageBox::Show( String::Concat( "The returned exception is: ", myReturnedException->Message ) );
}

The following example shows how to create a FileSystemWatcher to monitor file changes (creates, deletes, renames, changes) occurring on a disk drive. The example also shows how to properly receive error notifications.
