            Type type = a.GetType("domain.UI.News.Controls.TestAssembly");//此处必须为类的完整名称

            }
            MethodInfo method_add = type.GetMethod("add");//得到方法的信息
            string i = (string)method_add.Invoke(o, new object[] { 1, new int[] { 2, 6 }, new SqlParameter("@C_ID", "wangdetian"), new string[] { "12","11"} });//实现方法
