Question

我无法将我的WCF客户端连接到Localhost网络上的WCF服务器。我得到的错误如下：

连接到Localhost服务器时出错：找不到默认值引用合同的端点元素＆＃39; MyServiceReference.IMyService＆＃39; 在ServiceModel客户端配置部分中。这可能是因为找不到您的应用程序的配置文件，或者没有找到匹配此合同的端点元素可以在客户端元素中找到。

服务器连接如下。这是代码：

 _host = new ServiceHost(typeof(MyService));

 //Create Metadata exchange for the service
 ServiceMetadataBehavior mexBehavior = new ServiceMetadataBehavior();
 _host.Description.Behaviors.Add(mexBehavior);

 //Add service endpoints for the service and mex
 _host.AddServiceEndpoint(typeof(IMyService), new NetNamedPipeBinding(), "net.pipe://localhost/WFC_Server/MyService.svc");
 _host.AddServiceEndpoint(typeof(IMetadataExchange), MetadataExchangeBindings.CreateMexNamedPipeBinding(), "net.pipe://localhost/WFC_Server/MyService.svc/mex");
 _host.Open();

我没有设置我的客户端以正确连接到服务器。有人知道为什么吗？这是代码：

 var callback = new MyServiceCallback();
 var instanceContext = new InstanceContext(callback);
 var client = new MyServiceReference.MyServiceClient(instanceContext);
 client.Endpoint.Address = new EndpointAddress("net.pipe://localhost/WFC_Server/MyService.svc");
            client.OpenSession();

有人知道为什么我的客户端没有连接到服务器吗？

我已经复制了问题并修复了问题。 1.在创建客户端时指定端点地址。

 var callback = new MyServiceCallback();
                var instanceContext = new InstanceContext(callback);
                EndpointAddress remoteAddress = new EndpointAddress("net.pipe://localhost/WFC_Server/MyService.svc");
                var client = new MyServiceClient(instanceContext,new NetNamedPipeBinding(),remoteAddress);
                client.Hello(); // call the function

在服务器中，您可以这样注册：

代码：

            Uri address1 = new Uri("http://localhost/WFC_Server/");
            Uri address2 = new Uri("net.pipe://localhost/WFC_Server/");
            ServiceHost _host = new ServiceHost(typeof(MyService), address1,address2);

            //Create Metadata exchange for the service
            ServiceMetadataBehavior mexBehavior = new ServiceMetadataBehavior();
            mexBehavior.HttpGetEnabled = true;
            _host.Description.Behaviors.Add(mexBehavior);


            //Add service endpoints for the service and mex
           _host.AddServiceEndpoint(typeof(IMyService), new NetNamedPipeBinding(), "MyService.svc");

            _host.AddServiceEndpoint(
              ServiceMetadataBehavior.MexContractName,
              MetadataExchangeBindings.CreateMexHttpBinding(),
              "mex"
            );
            _host.Open();

我使用以下接口作为示例：

  class MyService : IMyService
    {
        public void Hello()
        {
         Console.WriteLine("Hello From Server..");
        }
    }

    [ServiceContract(CallbackContract = typeof(ICallbackService))]
    internal interface IMyService
   {
        [OperationContract]
        void Hello();
    }


    [ServiceContract]
    public interface ICallbackService
    {
        [OperationContract]
        void CallClient();
    }

WCF客户端无法连接到错误
