Throw
In Throw, the original exception stack trace will be retained. To keep the original stack trace information, the correct syntax is 'throw' without specifying an exception.
Declaration of throw
try
{
// do some operation that can fail
}
catch (Exception ex)
{
// do some local cleanup
throw;
}
|
Throw ex
In Throw ex, the original stack trace information will get override and you will lose the original exception stack trace. I.e. 'throw ex' resets the stack trace.
Declaration of throw ex
try
{
// do some operation that can fail
}
catch (Exception ex)
{
// do some local cleanup
throw ex;
}
}
