What is difference between "throw" and "throw e"

Hello Dilshad, 

 

"throw" maintains the full hierarchy in the stack trace and gives complete information about the exception occurred in the code. Whereas "throw ex" pretends that exceptions occurred on the line where "throw ex" was written and removes all the hierarchy above the method containing the "throw ex" expression.

Hi,

 

Whenever we write "throw e", we add the exception details to stack trace from new point. 

When we just "throw", we preserve the raw stack trace.

 

Here are few references for clarity
