C#异常

        private void Sub()
        {
            int n = 10;
            int m = 0;
            int d = n / m;
        }

        private void button3_Click(object sender, EventArgs e)
        {
            try
            {
                Sub();
            }
            catch (System.Exception ex)
            {
                Debug.WriteLine(ex.Message + ex.StackTrace.ToString());
            }
        }

ex.Message和ex.StackTrace.ToString()对于调试非常有帮助.
