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
};
}
}
除了不遵循这里不重复自己的规则(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,你说得对,但我会替换你的InitializeServices();使用以下代码。 它是伪代码,因此您需要替换位:)
1)在app.config中配置端点
2)从服务项目\程序集
获取服务类型 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终点并获得相应的服务实现然后创建你的主机
//在服务启动中读取您的终端
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,则迭代您的映射列表。
//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);
}
