c# - 如何以编程方式创建 BasicHttpBinding？

Question

我必须遵循以下代码:

BasicHttpBinding binding = new BasicHttpBinding ();

Uri baseAddress = new Uri ("URL.svc");

EndpointAddress endpointAddress = new EndpointAddress (baseAddress);

var myChannelFactory = new ChannelFactory<IMyInterface> (binding, endpointAddress);

IMyInterface client = null;

try
{
    client = myChannelFactory.CreateChannel ();
    var a = client.WsFunction ("XXXXXX");                    
    ((ICommunicationObject)client).Close ();
}
catch
{
    if (client != null)
    {
        ((ICommunicationObject)client).Abort ();
    }
}

“IMyInterface”是我的 WS 实现的接口(interface)。例如:

[ServiceContract]
public interface IMyInterface
{
    [OperationContract]
    Result WsFunction1 (string param);

    [OperationContract]
    Result WsFunction2 (string param);

    [OperationContract]
    Result WsFunction3 (string param);
}

它返回这样的东西:

[DataContract]
public class Result
{
    string a = "";
    string b = "";

    [DataMember]
    public string A
    {
        get { return a; }
        set { a = value; }
    }

    [DataMember]
    public string B
    {
        get { return b; }
        set { b = value; }
    }
}

当我运行这段代码时，我可以到达 WS，但我永远无法填写结果。

我做错了什么？

提前致谢!

通过 BasicHttpBinding 访问服务的最简单方法是从 SlSvcUtil.exe 生成客户端代码，这是一个 silverlight 实用程序。

SLsvcUtil.exe /directory:C:\users\me\Desktop http://URL.svc

这应该在它生成的文件中创建一个 MyInterfaceClient 类。

然后在您的代码中您可以:

var binding = new BasicHttpBinding() {
    Name = "BindingName",
    MaxBufferSize = 2147483647,
    MaxReceivedMessageSize = 2147483647
};

var endpoint = new EndpointAddress("URL.svc");

MyInterfaceClient client = new MyInterfaceClient(binding, endpoint);

client.WSFunctionCompleted += (object sender, WSFunctionCompletedEventArgs e) => {
    //access e.Result here
};

client.WSFunctionAsync("XXXXXX");

您的里程可能会有所不同。让我知道这个是否奏效。
