坚强的Finally

finally()很坚强，就算在try{}或者catch{}中已经返回了，但是finally()中的代码依旧会执行!

        public bool testFinallly()
        {

            int a = 0;

            try
            {
                a = 10;
                Console.WriteLine("Try");
                return true;

            }

            catch
            {
                Console.WriteLine("Catch");
                return false;

            }

            finally
            {
                a = 99;
                Console.WriteLine("finally , a={0}",a.ToString());
                //return true;//编译错误：控制不能离开finally子句主体

            }

            Console.WriteLine("out of finally");

        }

最后会输出：

Try

finally ,a=99
