Brilliant exception handling I found in an app i had to work on

    If this is C# (and it looks like it is), this leads to you losing the original stack trace up until this point.

    The correct way to do this in C# is to just throw; after you’re done with whatever you wanted to do in the catch.

      wait what ?

      So you are saying that the following code will keep throwing e but if I used throw e; it would basically be the same except for the stack trace that would be missing the important root cause ?!

      try {
} catch (WhateverException e) {
    // stuff, or nothing, or whatever
    throw; 
}

        Exactly. Aside from deleting your already built stack trace, as a bonus you’ll get another stack trace building call, enjoy wasted CPU cycles.
