Exception Handling

Question

how we can return some value in try-catch for example

try
{
  return abc;
}
catch(Exception ex)
{
console.Writeline("Exception occur" + ex);
}

Answer 1

try 
   { 
        return abc; 
   } 
catch(Exception ex) 
   { 
        console.Writeline("Exception occur" + ex); 
        return some_value;
   }

Answer 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.

Answer 3

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;
    }
}

Answer 4

You can return from anywhere.
