在运行时手动添加绑定

Question

由于与我的具体情况相关的原因，我尝试从 App.Config 文件中删除尽可能多的内容。我试图将其转移到代码中的项目之一是与 Web 服务相关的信息。我从 App.Config 中获取信息并创建了一个 BasicHttpBinding 类：

System.ServiceModel.BasicHttpBinding dss = new System.ServiceModel.BasicHttpBinding();
        dss.Security.Mode = System.ServiceModel.BasicHttpSecurityMode.None;
        dss.Security.Transport.ClientCredentialType = System.ServiceModel.HttpClientCredentialType.None;
        dss.Security.Transport.ProxyCredentialType = System.ServiceModel.HttpProxyCredentialType.None;
        dss.Security.Transport.Realm = "";

        dss.Security.Message.ClientCredentialType = System.ServiceModel.BasicHttpMessageCredentialType.UserName;

        dss.Name = "DataServiceSoap";
        dss.CloseTimeout = System.TimeSpan.Parse("00:01:00");
        dss.OpenTimeout = System.TimeSpan.Parse("00:01:00");
        dss.ReceiveTimeout = System.TimeSpan.Parse("00:10:00");
        dss.SendTimeout = System.TimeSpan.Parse("00:10:00");
        dss.AllowCookies = false;
        dss.BypassProxyOnLocal = false;
        dss.HostNameComparisonMode = System.ServiceModel.HostNameComparisonMode.StrongWildcard;
        dss.MaxBufferSize = 655360;
        dss.MaxBufferPoolSize = 524288;
        dss.MaxReceivedMessageSize = 655360;
        dss.MessageEncoding = System.ServiceModel.WSMessageEncoding.Text;
        dss.TextEncoding = new System.Text.UTF8Encoding();
        dss.TransferMode = System.ServiceModel.TransferMode.Buffered;
        dss.UseDefaultWebProxy = true;
        dss.ReaderQuotas.MaxDepth = 32;
        dss.ReaderQuotas.MaxStringContentLength = 8192;
        dss.ReaderQuotas.MaxArrayLength = 16384;
        dss.ReaderQuotas.MaxBytesPerRead = 4096;
        dss.ReaderQuotas.MaxNameTableCharCount = 16384;

之后，我创建了一个 Uri 来指向 Web 服务的地址：

Uri baseAddress = new Uri("http://localservice/dataservice.asmx");

最终如何添加客户端端点地址和绑定？我是否必须打开渠道，或者是否有一个更容易实现的类来解决这个问题？

这是使用 ChannelFactory 以编程方式执行此操作的简单方法。

        BasicHttpBinding binding = new BasicHttpBinding();
        EndpointAddress address = new EndpointAddress("Your uri here");

        ChannelFactory<IContract> factory = new ChannelFactory<IContract>(binding, address);
        IContract channel = factory.CreateChannel();
        channel.YourMethod();
        ((ICommunicationObject)channel).Close();
