我的任务是将数十个 WCF 服务转移到单个 Windows 服务。我使用 Windows 服务模板创建了一个 Windows 服务,并将以下代码添加到 ServiceHostController:

public partial class ServiceHostController : ServiceBase
{
    private List<ServiceHost> serviceHosts;

    public ServiceHostController()
    {
        InitializeComponent();
        this.ServiceName = "WCFServices";
        this.CanStop = true;
        this.AutoLog = true;
    }

    protected override void OnStart(string[] args)
    {
        if (serviceHosts != null)
        {
            foreach (var service in serviceHosts)
            {
                service.Close();
            }
        }

        InitializeServices();
        foreach (var service in serviceHosts)
        {
            service.Open();
        }
    }

    protected override void OnStop()
    {
        if (serviceHosts != null)
        {
            foreach (var service in serviceHosts)
            {
                service.Close();
            }
            serviceHosts.Close(); = null;
        }

        foreach (var service in serviceHosts)
        {
            service.Close();
        }
    }

    private void InitializeServices()
    {
        serviceHosts = new List<ServiceHost>()
        {
            new ServiceHost(typeof(WCFService1)),
            new ServiceHost(typeof(WCFService2)),
            // add dozens of services here
        };
    }
}

除了不遵循此处不要重复自己的规则(实际代码不同)之外,我应该如何在 Windows 服务代码中托管这些 WCF 服务?

汉斯,你做对了,但我会替换你的 InitializeServices(); 使用以下代码。它是伪代码,因此您需要替换这些位:)

1) 在 app.config 中配置您的端点

2) 从您的服务项目\程序集中获取您的服务类型

  Dictionary<Type, Type> mappings = new Dictionary<Type,Type>();

   foreach (Type t in MyServiceAssembly.GetTypes())
  {
    if (t.GetInterfaces().Length > 0)
    {
      foreach (Type ti in t.GetInterfaces())

        {
          if (mapping.ContainsKey(ti))
            System.Diagnostics.Debug.WriteLine("Class {0} implements more than one interface {1}", t.FullName, ti.FullName);
          else
            mapping.Add(ti, t);

          // System.Diagnostics.Debug.WriteLine("Class {0} implements {1}", t.FullName, ti.FullName);
        }
    }
  }

4)如果你想从 app.config 控制端点现在迭代你的端点并获得相应的服务实现然后创建你的主机

//在你的服务启动中读取你的端点

 List<ServiceHost> serviceHosts = new List<ServiceHost>();

     ServicesSection servicesSection = (ServicesSection)WebConfigurationManager.GetSection("system.serviceModel/services");  

    for(int i = 0;i<servicesSection.Services.Count;i++)
    {
    ServiceEndpointElement endpoint = servicesSection.Services[i].Endpoints[0];  
    string url = string.Format("net.tcp://{0}:{1}/YouNameSpace_service_Name_From_EndPoint/{2}.svc","YourHost","YourPort");
      ServiceHost serviceHost = new ServiceHost(mappings[endpoint.Contract] , new Uri(url));

              serviceHost.Open();

              mServiceHosts.Add(serviceHost);
    }

5) 如果您不想从 app.config 控制端点, 请遍历您的映射列表。

//在您的服务启动中执行此操作

 List<ServiceHost> serviceHosts = new List<ServiceHost>();

     foreach(type t in mappings.Keys)
    {
            string url = string.Format("net.tcp://{0}:{1}/YouNameSpace_{2}.svc","YourHost","YourPort",t.name);
      ServiceHost serviceHost = new ServiceHost(mappings[t] , new Uri(url));

              serviceHost.Open();

              mServiceHosts.Add(serviceHost);
    }
