Throw VS rethrow : same result?

Question

refering to a lot of documentation on the net, particularly on SO, eg : What is the proper way to re-throw an exception in C#? there should be a difference between \"throw e;\"

Answer 1

I can't replicate the problem -- using .NET 3.5 (32-bit) gives me the same results described in Bart's article.

My guess is that the .NET 4 compiler/jitter -- or maybe it's the 64-bit compiler/jitter if this is happening under 3.5 too -- is inlining the BadGuy method into the calling methods. Try adding the following MethodImpl attribute to BadGuy and see if that makes any difference:

[MethodImpl(MethodImplOptions.NoInlining | MethodImplOptions.NoOptimization)]
private static void BadGuy()
{
    //
    // Some nasty behavior.
    //
    throw new Exception();
}
