Some people asked me the different between those two following code:
Code 1
try
{
...
}
catch (Exception ex)
{
throw ex;
}
Code 2
try
{
...
}
catch (Exception ex)
{
throw;
}
I don’t think there is ever a good reason to write catch (Exception e) { throw e; }. This loses the original stacktrace. When you use throw; the original stacktrace is preserved. This is good because it means that the cause of the error is easier to find.
