Wcf 什么'；这是ChannelFactory与lt；T>；和ClientBase<；T>；

你能给我解释一下ChannelFactory和ClientBase之间的区别吗？它们中哪一个更适合用于SelfHost客户机-服务器应用程序

using(ChannelFactory<MyInterface> cf = new ChannelFactory<MyInterface>("Endpoint From Web.Config")){} 

public class MyClient : ClientBase<MyInterface>, MyInterface {}

使用（ChannelFactory cf=newchannelfactory（“来自Web.Config的端点”）{}
公共类MyClient:ClientBase，MyInterface{}

谢谢

让我们有一个定义合同的界面：

[ServiceContract]
public interface TheInterface
{
    [OperationContract]
    string DoWork( string Work );
}

ChannelFactory

自动创建一个仅实现接口的代理

 var factory = new ChannelFactory<TheInterface>( new BasicHttpBinding() );
 var address = new EndpointAddress( "http://..." );
 var client = factory.CreateChannel( address );

 // there are no other methods on the "client" reference
 // than the interface's DoWork method
 client.DoWork( "foo" );

然后

var address = new EndpointAddress( "http://..." );

using ( var client = new TheInterfaceProxy( new BasicHttpBinding(), address ) )
{
     // DoWork is here
     // but multiple other members are there too
     // for example - applying a custom endpoint behavior:
     client.Endpoint.EndpointBehaviors.Add( new InspectorBehavior() );

     client.DoWork( "bar" );
}

其中，使用示例简单行为检查客户端的传入/传出消息

class InspectorBehavior : IEndpointBehavior
{
    #region IEndpointBehavior Members

    public void AddBindingParameters( ServiceEndpoint endpoint, System.ServiceModel.Channels.BindingParameterCollection bindingParameters )
    {
    }

    public void ApplyClientBehavior( ServiceEndpoint endpoint, System.ServiceModel.Dispatcher.ClientRuntime clientRuntime )
    {
        clientRuntime.ClientMessageInspectors.Add( new DispatchInspector() );
    }

    public void ApplyDispatchBehavior( ServiceEndpoint endpoint, System.ServiceModel.Dispatcher.EndpointDispatcher endpointDispatcher )
    {
    }

    public void Validate( ServiceEndpoint endpoint )
    {
    }

    #endregion
}

class DispatchInspector : IClientMessageInspector
{
    #region IClientMessageInspector Members

    public void AfterReceiveReply( ref Message reply, object correlationState )
    {
        MessageBuffer buffer = reply.CreateBufferedCopy( Int32.MaxValue );
        reply = buffer.CreateMessage();
        Console.WriteLine( "Receiving:\n{0}", buffer.CreateMessage().ToString() );
    }

    public object BeforeSendRequest( ref Message request, IClientChannel channel )
    {
        MessageBuffer buffer = request.CreateBufferedCopy( Int32.MaxValue );
        request = buffer.CreateMessage();
        Console.WriteLine( "Sending:\n{0}", buffer.CreateMessage().ToString() );

        return null;
    }

    #endregion
}

但是，没有哪个答案更好：

• 如果您不需要任何东西，只需要默认行为-您可以坚持使用

  ChannelFactory

  ，这是两种方法中最简单的一种
• 对于任何额外的内容，请使用

  ClientBase

  ，但它需要一个额外的类

您好，Wiktor，非常感谢您的回复。检查InspectorBehavior和DispatchInspector在客户端计算InterfaceProxy类的行为还是什么？如果是，这两个类与InterfaceProxy类之间的连接如何。您似乎错过了这行代码

client.Endpoint.EndpointBehaviors.Add（new-InspectorBehavior（））

将检查器添加到交互代理的行为中。使用channel factory创建的代理无法执行此操作。您好，谢谢。我现在知道ChannelFactory和ClientBase编程的区别了。但是，异步运行、切换、资源消耗和速度等其他差异又如何呢？这两个类是基于Rest还是SOAP的？在我看来，这些附加问题远远超出了原始问题的范围。考虑接受这个答案，并提出另外一些具体的问题来解决你的担忧。请注意，被认为“过于宽泛”的问题可能会被社区搁置。您好，Wiktor，对不起，但这些是我关于ChannelFactory和ClientBase之间差异的真正问题。当做

class InspectorBehavior : IEndpointBehavior
{
    #region IEndpointBehavior Members

    public void AddBindingParameters( ServiceEndpoint endpoint, System.ServiceModel.Channels.BindingParameterCollection bindingParameters )

    public void ApplyClientBehavior( ServiceEndpoint endpoint, System.ServiceModel.Dispatcher.ClientRuntime clientRuntime )
    {
        clientRuntime.ClientMessageInspectors.Add( new DispatchInspector() );
    }

    public void ApplyDispatchBehavior( ServiceEndpoint endpoint, System.ServiceModel.Dispatcher.EndpointDispatcher endpointDispatcher )
    {
    }

    public void Validate( ServiceEndpoint endpoint )
