class Exceptions typically leave the current codepath right away and make use of automatic cleanup mechanisms (e.g. there is no need to manually clean up the stack). In order to throw an exception from the VM you usually only need to free the opcode operands and invoke HANDLE_EXCEPTION(). Exceptions have the additional advantage of providing a stack Raise an exception.

Exception handling is used to change the normal flow of the code execution if a specified error (exceptional) condition occurs. This condition is called an exception. This is what normally happens when an exception is triggered: Dim baseException As System.Exception = ex.GetBaseException() Dim baseExceptionMessage As String = "" If (Not baseException Is Nothing) Then baseExceptionMessage = baseException.Message End If WriteLine("Caught an expected exception:") WriteLine(entireException) WriteLine(vbCrLf + "Properties of the exception are as follows:") WriteLine("Message: " + message) WriteLine("Source 2020-06-17 · A Computer Science portal for geeks.
