            }
            catch (Exception ex)
            {
                Console.WriteLine("\n在Level1中执行Exception,注意是Exception ");
                Console.WriteLine(ex);
            }
            finally
            {
                Console.WriteLine("\n在Level1中执行finally ");
            }
            Console.ReadKey();//程序暂停
        }
    }
    class Exception1 : Exception
    {
    }
    class Exception2 : Exception
    {
    }
    class Exception3 : Exception
    {
    }
}

以上是一个测试try-catch-finally语句的C#代码,Let”s 玩!
