動態調用WCF服務

Question

我已經創建了ASP.NET應用程序並向其添加了簡單的WCF服務。 ASP.NET應用程序是WCF服務的主機。該服務正在運行。

服務如下所示：

[ServiceContract] 
public interface IService1 
{ 
    [OperationContract] 
    string DoWork(string text); 
} 

public class Service1 : IService1 
{ 
    public string DoWork(string text) 
    { 
     return text.ToUpper(); 
    } 
} 

在客戶端是應該動態地調用WCF服務的控制檯應用程序。我用下面的代碼：

WSHttpBinding binding = new WSHttpBinding(SecurityMode.None); 
IChannelFactory<IRequestChannel> factory = binding.BuildChannelFactory<IRequestChannel>(
    new BindingParameterCollection()); 
factory.Open(); 

EndpointAddress address = new EndpointAddress("http://localhost:3929/Service1.svc"); 
IRequestChannel irc = factory.CreateChannel(address); 
using (irc as IDisposable) 
{ 
    irc.Open(); 

    XmlReader reader = XmlReader.Create(new StringReader(
     @"<DoWork xmlns='http://tempuri.org/'> 
     <composite xmlns:a='http://www.w3.org/2005/08/addressing' 
     xmlns:i='http://www.w3.org/2001/XMLSchema-instance'> 
     <a:StringValue>aaaa</a:StringValue> 
     </composite> 
     </DoWork>")); 

    Message m = Message.CreateMessage(MessageVersion.Soap12, 
       "http://tempuri.org/IService1/DoWork", reader); 

    Message ret = irc.Request(m); 
    reader.Close(); 

    Console.WriteLine(ret); 
} 

//close the factory 
factory.Close(); 

但是，它崩潰這一行：

Message ret = irc.Request(m); 

與以下錯誤：

The message version of the outgoing message (Soap12 (http://www.w3.org/2003/05/soap-envelope) AddressingNone (http://schemas.microsoft.com/ws/2005/05/addressing/none)) does not match that of the encoder (Soap12 (http://www.w3.org/2003/05/soap-envelope) Addressing10 (http://www.w3.org/2005/08/addressing)). Make sure the binding is configured with the same version as the message.

有誰知道我做錯了嗎？

預先感謝您。

Answer 1

Message.CreateMessage(MessageVersion.Soap12, 

取而代之的是MessageVersion枚舉值Soap12，你需要指定Soap12Addressing10以配合您的約束力。
