Type InvokeMember()用法简介

 举例：
   Type tDate = typeof(System.DateTime);
    Object result = tDate.InvokeMember("Now", 
            BindingFlags.GetProperty, null, null, new Object[0]);
    Console.WriteLine(result.ToString());

   例2：  /*注意：下面备注的方法都是其他类的方法，比如：TestClass类方法*/
   TestClass tc = new TestClass (); //AddUp为tc的方法
   tc.GetType().InvokeMember ("AddUp", BindingFlags.Public |
                BindingFlags.Instance | BindingFlags.CreateInstance,
                null, tc, new object [] {});
	/*
	    public void AddUp ()
        {
            methodCalled++;
            Console.WriteLine ("AddUp Called {0} times", methodCalled);
        }
	*/
	//----------------------------下面传参数 执行ComputeSum方法 带有两个参数
	Type t = typeof (TestClass);
   object [] args = new object [] {100.09, 184.45};
   object result = t.InvokeMember ("ComputeSum", BindingFlags.InvokeMethod, null, null, args);
    /*
	    public static double ComputeSum (double d1, double d2)
        {
            return d1 + d2;
        }
	*/
   //-----------SayHello为静态方法调用
    t.InvokeMember ("SayHello", BindingFlags.InvokeMethod | BindingFlags.Public | BindingFlags.Static, null, null, new object [] {});
   //-----------实例方法调用
    TestClass c = new TestClass ();
   c.GetType().InvokeMember ("AddUp", BindingFlags.InvokeMethod, null, c, new object [] {});

   c.GetType().InvokeMember ("AddUp", BindingFlags.Public |
                BindingFlags.Instance | BindingFlags.CreateInstance,
                null, c, new object [] {});

   //----------获取字段
    result = t.InvokeMember ("Name", BindingFlags.GetField | BindingFlags.GetProperty, null, c, new object [] {});
    result = t.InvokeMember ("Value", BindingFlags.GetField | BindingFlags.GetProperty, null, c, new object [] {}); 
	/*
	    public String Name;
	    public Object Value
        {
            get
            {
                return "the value";
            }
        }
	*/
    result = t.InvokeMember ("Name", BindingFlags.GetField, null, c, new object [] {});
   //---------设置字段
    t.InvokeMember ("Name", BindingFlags.SetField, null, c, new object [] {"NewName"}); //NewName设置的属性值
   //---------调用类方法 带参数
    object[] argValues = new object [] {"Mouse", "Micky"};
    String [] argNames = new String [] {"lastName", "firstName"};
    t.InvokeMember ("PrintName", BindingFlags.InvokeMethod, null, null, argValues, null, null, argNames);
    /*
	    public static void PrintName (String firstName, String lastName)
        {
            Console.WriteLine ("{0},{1}", lastName,firstName);
        }

	TestClass obj = new TestClass();
	System.Reflection.MethodInfo methInfo =
                obj.GetType().GetMethod("PrintName");

	/*
