This code will return 2 (exception occured) if you call the method.

int testException() { try { int a = 0; int b = 0; return a / b; //return 1; } catch (System.Exception ex) { return 2; } }

Try Catch is a way of handling errors in your code that cause you to need to leave the normal flow of the program. Many .net system components throw errors to indicate a condition that is not expected any code can be put in a catch block;

object x; try { x = Func(); } catch(Exception e) { //Set some default Value x = new Object(); //Send an email error SendErrorMail(); } return x;

If you just need to return inside of a catch you can use a return statement just like you would anywhere else in your code.

sorry if my statement is confusing you actually i want to return some values in try cage.

Returning an error code from a catch block somewhat defeats the purpose of exceptions.
