I've always thought the difference between "throw" and "throw ex" was that throw alone wasn't resetting the stacktrace of the exception.
Unfortunately, that's not the behavior I'm experiencing ; here is a simple sample reproducing my issue :
using System;
using System.Text;
namespace testthrow2
{
class Program
{
static void Main(string[] args)
{
try
{
try
{
throw new Exception("line 14");
}
catch (Exception)
{
throw; // line 18
}
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
Console.ReadLine();
}
}
}
I would expect this code to print a callstack starting at line 14 ; however the callstack starts at line 18. Of course it's no big deal in the sample, but in my real life application, losing the initial error information is quite painful.
Am I missing something obvious? Is there another way to achieve what I want (ie re throwing an exception without losing the stack information?)
I'm using .net 3.5
