Keeping Exception.StackTrace Intact when Rethrowing an Exception
Nick Weinholt (.Net Performance guru and MVP) has an article on the correct method for rethrowing an exception in C# so that the Exception.StackTrace actually points to the root problem.
In C# the correct method for rethowing an exception is using throw; without any arguments within the catch block:
try {
// code
}
catch (Exception ex) {
throw; // Rethrow exception without resetting StackTrace
}
// code
}
catch (Exception ex) {
throw; // Rethrow exception without resetting StackTrace
}
In VB.Net the method is the same:
Try
' code
Catch ex As Exception
Throw ' Rethrow exception without resetting StackTrace
End Try
' code
Catch ex As Exception
Throw ' Rethrow exception without resetting StackTrace
End Try
Using this method the stack trace will go all the way down to the original exception, and not just to your catch block.
