动态调用WCF服务

Question

我已经创建了ASP.NET应用程序并向其添加了简单的WCF服务。 ASP.NET应用程序是WCF服务的主机。该服务正在运行。

服务如下所示：

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

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

在客户端是应该动态地调用WCF服务的控制台应用程序。我用下面的代码：

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，它崩溃这一行：

Message ret = irc.Request(m); 

与以下错误：

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.

有谁知道我做错了吗？

预先感谢您。

Answer 1

Message.CreateMessage(MessageVersion.Soap12, 

取而代之的是MessageVersion枚举值Soap12，你需要指定Soap12Addressing10以配合您的约束力。
