Question

Answer 1

You should always use "throw;" to rethrow the exceptions in .NET,

Refer this, http://weblogs.asp.net/bhouse/archive/2004/11/30/272297.aspx

Basically MSIL (CIL) has two instructions - "throw" and "rethrow":

• C#'s "throw ex;" gets compiled into MSIL's "throw"
• C#'s "throw;" - into MSIL "rethrow"!

Basically I can see the reason why "throw ex" overrides the stack trace.
