使用单个合约运行 ServiceHost 工作正常，如下所示:

Running a ServiceHost with a single contract is working fine like this:

servicehost = new ServiceHost(typeof(MyService1));
servicehost.AddServiceEndpoint(typeof(IMyService1), new NetTcpBinding(), "net.tcp://127.0.0.1:800/MyApp/MyService1");
servicehost.Open();

现在我想添加第二份(第 3、第 4、...)份合同.我的第一个猜测是添加更多这样的端点:

Now I'd like to add a second (3rd, 4th, ...) contract. My first guess would be to just add more endpoints like this:

servicehost = new ServiceHost(typeof(MyService1));
servicehost.AddServiceEndpoint(typeof(IMyService1), new NetTcpBinding(), "net.tcp://127.0.0.1:800/MyApp/MyService1");
servicehost.AddServiceEndpoint(typeof(IMyService2), new NetTcpBinding(), "net.tcp://127.0.0.1:800/MyApp/MyService2");
servicehost.Open();

但这当然不起作用，因为在创建 ServiceHost 时，我可以将 MyService1 作为参数或 MyService2 传递 - 所以我可以向我的服务添加很多端点，但都必须使用相同的合同，因为我只能提供一种实现吗?
我觉得我错过了重点，在这里.确定必须有某种方法为我添加的每个端点合同提供实现吗?

But of course this does not work, since in the creation of ServiceHost I can either pass MyService1 as parameter or MyService2 - so I can add a lot of endpoints to my service, but all have to use the same contract, since I only can provide one implementation?
I got the feeling I'm missing the point, here. Sure there must be some way to provide an implementation for every endpoint-contract I add, or not?

推荐答案

您需要在同一个类中实现两个服务(接口).

You need to implement both services (interfaces) in the same class.

servicehost = new ServiceHost(typeof(WcfEntryPoint));
servicehost.Open(); 

public class WcfEntryPoint : IMyService1, IMyService2
{
    #region IMyService1
    #endregion

    #region IMyService2
    #endregion
}

仅供参考:我经常使用部分类来使我的宿主类代码更易于阅读:

FYI: I frequently use partial classes to make my host class code easier to read:

// WcfEntryPoint.IMyService1.cs
public partial class WcfEntryPoint : IMyService1
{
    // IMyService1 methods
}

// WcfEntryPoint.IMyService2.cs
public partial class WcfEntryPoint : IMyService2
{
    // IMyService2 methods
}
