如果不需要IoC或使用自动生成的客户端(服务引用)，那么可以简单地使用包装器来管理关闭，并在客户端处于安全状态(不会抛出任何异常)时让GC接管客户端。GC将在serviceclient中调用Dispose，而这个将调用Close。因为它已经关闭了，所以不会造成任何损害。我使用这个没有问题的生产代码。

public class AutoCloseWcf : IDisposable
{

    private ICommunicationObject CommunicationObject;

    public AutoDisconnect(ICommunicationObject CommunicationObject)
    {
        this.CommunicationObject = CommunicationObject;
    }

    public void Dispose()
    {
        if (CommunicationObject == null)
            return;
        try {
            if (CommunicationObject.State != CommunicationState.Faulted) {
                CommunicationObject.Close();
            } else {
                CommunicationObject.Abort();
            }
        } catch (CommunicationException ce) {
            CommunicationObject.Abort();
        } catch (TimeoutException toe) {
            CommunicationObject.Abort();
        } catch (Exception e) {
            CommunicationObject.Abort();
            //Perhaps log this

        } finally {
            CommunicationObject = null;
        }
    }
}

然后，当你访问服务器时，你创建客户端，并在autodisconnect中使用using:

var Ws = new ServiceClient("netTcpEndPointName");
using (new AutoCloseWcf(Ws)) {

    Ws.Open();

    Ws.Test();
}

您还可以使用DynamicProxy来扩展Dispose()方法。你可以这样做:

using (var wrapperdProxy = new Proxy<yourProxy>())
{
   // Do whatever and dispose of Proxy<yourProxy> will be called and work properly.
}

我使用Castle动态代理来解决Dispose()问题，并在通道处于不可用状态时实现自动刷新。要使用此功能，必须创建一个继承服务契约和IDisposable的新接口。动态代理实现了这个接口，并封装了一个WCF通道:

Func<object> createChannel = () =>
    ChannelFactory<IHelloWorldService>
        .CreateChannel(new NetTcpBinding(), new EndpointAddress(uri));
var factory = new WcfProxyFactory();
var proxy = factory.Create<IDisposableHelloWorldService>(createChannel);
proxy.HelloWorld();

我喜欢这样做，因为您可以注入WCF服务，而使用者无需担心WCF的任何细节。它不像其他解那样有额外的麻烦。

看一下代码，其实很简单: WCF动态代理

重写客户端的Dispose()，而不需要基于ClientBase生成代理类，也不需要管理通道创建和缓存!(注意WcfClient不是一个ABSTRACT类，而是基于ClientBase)

// No need for a generated proxy class
//using (WcfClient<IOrderService> orderService = new WcfClient<IOrderService>())
//{
//    results = orderService.GetProxy().PlaceOrder(input);
//}

public class WcfClient<TService> : ClientBase<TService>, IDisposable
    where TService : class
{
    public WcfClient()
    {
    }

    public WcfClient(string endpointConfigurationName) :
        base(endpointConfigurationName)
    {
    }

    public WcfClient(string endpointConfigurationName, string remoteAddress) :
        base(endpointConfigurationName, remoteAddress)
    {
    }

    public WcfClient(string endpointConfigurationName, System.ServiceModel.EndpointAddress remoteAddress) :
        base(endpointConfigurationName, remoteAddress)
    {
    }

    public WcfClient(System.ServiceModel.Channels.Binding binding, System.ServiceModel.EndpointAddress remoteAddress) :
        base(binding, remoteAddress)
    {
    }

    protected virtual void OnDispose()
    {
        bool success = false;

        if ((base.Channel as IClientChannel) != null)
        {
            try
            {
                if ((base.Channel as IClientChannel).State != CommunicationState.Faulted)
                {
                    (base.Channel as IClientChannel).Close();
                    success = true;
                }
            }
            finally
            {
                if (!success)
                {
                    (base.Channel as IClientChannel).Abort();
                }
            }
        }
    }

    public TService GetProxy()
    {
        return this.Channel as TService;
    }

    public void Dispose()
    {
        OnDispose();
    }
}

像这样的包装器可以工作:

public class ServiceClientWrapper<ServiceType> : IDisposable
{
    private ServiceType _channel;
    public ServiceType Channel
    {
        get { return _channel; }
    }

    private static ChannelFactory<ServiceType> _channelFactory;

    public ServiceClientWrapper()
    {
        if(_channelFactory == null)
             // Given that the endpoint name is the same as FullName of contract.
            _channelFactory = new ChannelFactory<ServiceType>(typeof(T).FullName);
        _channel = _channelFactory.CreateChannel();
        ((IChannel)_channel).Open();
    }

    public void Dispose()
    {
        try
        {
            ((IChannel)_channel).Close();
        }
        catch (Exception e)
        {
            ((IChannel)_channel).Abort();
            // TODO: Insert logging
        }
    }
}

这应该使您能够编写如下代码:

ResponseType response = null;
using(var clientWrapper = new ServiceClientWrapper<IService>())
{
    var request = ...
    response = clientWrapper.Channel.MyServiceCall(request);
}
// Use your response object.

如果需要的话，包装器当然可以捕获更多的异常，但原理是一样的。

我在这篇文章中提到了一些答案，并根据我的需要定制了它。

我想在使用WCF客户端之前做一些事情，所以使用DoSomethingWithClient()方法。

public interface IServiceClientFactory<T>
{
    T DoSomethingWithClient();
}
public partial class ServiceClient : IServiceClientFactory<ServiceClient>
{
    public ServiceClient DoSomethingWithClient()
    {
        var client = this;
        // do somthing here as set client credentials, etc.
        //client.ClientCredentials = ... ;
        return client;
    }
}

下面是helper类:

public static class Service<TClient>
    where TClient : class, ICommunicationObject, IServiceClientFactory<TClient>, new()
{
    public static TReturn Use<TReturn>(Func<TClient, TReturn> codeBlock)
    {
        TClient client = default(TClient);
        bool success = false;
        try
        {
            client = new TClient().DoSomethingWithClient();
            TReturn result = codeBlock(client);
            client.Close();
            success = true;
            return result;
        }
        finally
        {
            if (!success && client != null)
            {
                client.Abort();
            }
        }
    }
}

我可以把它用作:

string data = Service<ServiceClient>.Use(x => x.GetData(7));
