一个WCF [MessageContract]

Question

类

的WPF数据绑定的问题我已经在服务器

[MessageContract] 
public class RemoteFileInfo : IDisposable, INotifyPropertyChanged 
{ 
    [MessageHeader(MustUnderstand = true)] 
    public string _FileName; 

    [MessageHeader(MustUnderstand = true)] 
    public string FileName 
    { 
     get { return _FileName; } 
     set { _FileName = value; } 
    } 


    [MessageBodyMember(Order = 1)] 
    public System.IO.Stream _FileByteStream; 

    [MessageHeader(MustUnderstand = true)] 
    public System.IO.Stream FileByteStream 
    { 
     get { return _FileByteStream; } 
     set { _FileByteStream = value; } 
    } 

    public void Dispose() 
    { 
     // close stream when the contract instance is disposed. 
     // this ensures that stream is closed when file download 
     // is complete, since download procedure is handled by the client 
     // and the stream must be closed on server. 
     if (_FileByteStream!=null) 
     { 
      _FileByteStream.Close(); 
      _FileByteStream = null; 
     } 
    } 

    #region INotifyPropertyChanged Members 

    public event PropertyChangedEventHandler PropertyChanged; 

    protected virtual void SendPropertyChanged(String propertyName) 
    { 
     if ((this.PropertyChanged != null)) 
     { 
      this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); 
     } 
    } 

    #endregion 
} 

我通过WCF我的服务器进行通信的一类。这个类应该是[MessageContract]，因为流式传输 - （我的所有其他类无论如何都使用[DataContract]）。

我的问题是，经过我产生在客户端与SvcUtil工具类我失去了inotify的... ...界面我得到这样的：

[System.Diagnostics.DebuggerStepThroughAttribute()] 
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0")] 
[System.ServiceModel.MessageContractAttribute(WrapperName="RemoteFileInfo", WrapperNamespace="http://tempuri.org/", IsWrapped=true)] 
public partial class RemoteFileInfo 
{ 
    [System.ServiceModel.MessageHeaderAttribute(Namespace="http://tempuri.org/")] 
    public System.IO.Stream FileByteStream; 

    [System.ServiceModel.MessageHeaderAttribute(Namespace="http://tempuri.org/")] 
    public string FileName; 

    [System.ServiceModel.MessageHeaderAttribute(Namespace="http://tempuri.org/")] 
    public string _FileName; 

    [System.ServiceModel.MessageBodyMemberAttribute(Namespace="http://tempuri.org/", Order=0)] 
    public System.IO.Stream _FileByteStream; 

    public RemoteFileInfo() 
    { 
    } 

    public RemoteFileInfo(
       System.IO.Stream FileByteStream, 
       string FileName, 
       string _FileName, 
       System.IO.Stream _FileByteStream) 
    { 
     this.FileByteStream = FileByteStream; 
     this.FileName = FileName; 
     this._FileName = _FileName; 
     this._FileByteStream = _FileByteStream; 
    } 
} 

没有INotifyPropertyChanged的数据绑定不工作，我知道但我可以在客户端添加它，因为我这样做：

public partial class RemoteFileInfo : System.ComponentModel.INotifyPropertyChanged 
{ 
    #region INotifyPropertyChanged Members 

    public event System.ComponentModel.PropertyChangedEventHandler PropertyChanged; 

    #endregion 
} 

但仍然数据绑定不起作用。你有什么主意吗？ 我无法使用[MessageContract]类的数据绑定？

感谢您的提前解答！

消息协定只规定消息的结构。服务器端的任何接口都不会出现在客户端，因为它们与消息的结构无关。

此外，如果您的客户端是用Java编写的，那么这些接口会有什么作用？
