What does catch { throw; } do?

Question

I just found this gem in the pile of spaghetti I have to maintain:

try { Foo(); }
catch { throw; }

Is it safe to replace it with

Foo();

?

Yes, those two statements are equal in what they do. However 1st one does one extra throw if exception occurs. — Aurimas Neverauskas, Nov 07 '14 at 14:07

Yes. It's exactly the same. Maybe someone used it to put a breakpoint in the catch block.

Yes, it is safe to delete try/catch here. Often such code created in iterations: initially it was exceptions processing there, but later it was lazily removed.
