WCF - 消息和消息緩衝區關閉

Question

Msdn says： 消息還處置用於構建物體時使用的對象。

從這我推斷是關閉消息也關閉它創建的MessageBuffer。但在實際的代碼中，情況並非如此。關閉消息會將messagebuffer.closed留爲false。

應如何關閉從該緩衝區創建的消息緩衝區和消息？

下面的源代碼將幫助您瞭解如何使用從消息緩衝區創建的消息。

using System; 
using System.Collections.Generic; 
using System.Text; 
using System.ServiceModel; 
using System.ServiceModel.Channels; 

namespace _22756512 { 
    class Program { 
     static void Main(string[] args) { 
      Order order = new Order() { Id = 1, CustomerName = "Smith" }; 
      var message = Message.CreateMessage(MessageVersion.Default, "http://127.0.0.1/someaction", order); 
      Console.WriteLine("message.state after creation: " + message.State.ToString()); 

      using (MessageBuffer buffer = message.CreateBufferedCopy(int.MaxValue)) { 
       Console.WriteLine("message.state after create bufferedcopy: " + message.State.ToString()); 

       using (var anotherMessage = buffer.CreateMessage()) { 
        var anotherOrder = anotherMessage.GetBody<Order>(); 
        Console.WriteLine("anotherOrder.Id = " + anotherOrder.Id); 
        Console.WriteLine("antherOrder.customername = " + anotherOrder.CustomerName); 
       } 

       using (var the3rdMessage = buffer.CreateMessage()) { 
        var the3rdOrder = the3rdMessage.GetBody<Order>(); 
        Console.WriteLine("3rd order.id = " + the3rdOrder.Id); 
        Console.WriteLine("3rd order.customer name = " + the3rdOrder.CustomerName); 
       } 
      } 

      message.Close(); 
      Console.WriteLine("message.state after close: " + message.State.ToString()); 
      Console.Read(); 
     } 
    } 

    public class Order { 
     public Int32 Id { get; set; } 
     public String CustomerName { get; set; } 
    } 
}
