        static void Main(string[] args)
        {
            System.Reflection.Assembly ass = System.Reflection.Assembly.LoadFile(@"C:\testclass.dll");
            Type type;
            object obj;
            type = ass.GetType("testclass.Class1");//必须使用名称空间+类名称
            obj = ass.CreateInstance("testclass.Class1");//必须使用名称空间+类名称

           
            System.Reflection.MethodInfo method = type.GetMethod("GetName1");//方法的名称
            string s = (string)method.Invoke(obj, null); //实例方法的调
            Console.WriteLine(s);

            method = type.GetMethod("GetName2");
            s = (string)method.Invoke(obj, new string[] { "你好!" });
            Console.WriteLine(s);
        }
