C# 模拟测试时找不到合同名称。

我在兜圈子，试图找出这个错误。我正在使用moq框架执行模拟测试。测试代码是

[TestFixture]
[ServiceContract]
public class UnitTest1
{

    private ServiceHost host;
    [Test]
    public void TestMethod()
    {
        Mock mk = new Mock<ChatInterfaces.IChatService>();
        host = new ServiceHost(mk);
        host.AddServiceEndpoint(typeof(IChatService), new NetTcpBinding()
            , "net.tcp://localhost:8080/ChatService");
        host.Open();
        Console.WriteLine("Testing");

---

我在这里做错了什么？如何修复它？谢谢

尝试使用

mk.Object

来实际获取

IChatService

实现，而不是

Mock

对象

Mock<ChatInterfaces.IChatService> mk = new Mock<ChatInterfaces.IChatService>();
host = new ServiceHost(mk.Object);

Mock mk=new Mock（）；
主机=新服务主机（mk.Object）；

Result Message: System.InvalidOperationException : The contract name     'ChatInterfaces.IChatService' could not be found in the list of contracts implemented by the service 'Moq.Mock`1[[ChatInterfaces.IChatService, ChatInterfaces, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]'.

Mock<ChatInterfaces.IChatService> mk = new Mock<ChatInterfaces.IChatService>();
host = new ServiceHost(mk.Object);
