C# Throw Semantics

Question

Are the following code snippets essentially equivalent?

catch(Exception E) {
  ...
  throw E;  //Explicitly rethrow the exception
}

and

catch(Exception E) {
  ...
  throw;    //Implicitly rethrow the exception
}

Answer 2

NO.

catch(Exception E) 
{
  ...
  throw E;  //Explicitly rethrow the exception
}

This one restarts the stack trace, while throw keeps the stack trace and adds to it.

IF you are going to rethrow the exception use throw.
