Question

Is it possible to use return statement in try block?.How,What is the use of the statement.

Answer 1

You can return from within a try block, but keep in mind that the code in the finally clause will be executed before returning from the method. For example, calling MessageBox.Show(test().ToString()); using the method below will cause two message boxes to appear (the first displaying "3" and the second displaying "1").

    int test()
    {
        try
        {
            return 1;
            throw new Exception();
        }
        catch (Exception e)
        {
            return 2;
        }
        finally
        {
            MessageBox.Show("3");
        }
    }

Answer 2

Sure, you can use return in a try block, and the syntax is just like everywhere else.

try
{
    return 0;
}
catch (Exception e)
{
    // handle exception
}

Answer 3

Yes.

I can use local variables without having to widen their scope, for example.

int Foo(string bar) {
    try {
        int biz = int.Parse(bar);

        return biz;
    } catch(...) {
        // Handle bad `bar`
    }
}

    {
       throw;
       //or return here
    }
}
