Windows 服务中托管的 WCF 服务

Question

我已经创建了一个 windows 服务托管。此 windows 服务正在托管一个简单的 wcf 服务。之后我安装了服务。但是我在 services.msc.

中看不到它

namespace Microsoft.ServiceModel.Samples
{
    // Define a service contract.
    [ServiceContract(Namespace = "http://Microsoft.ServiceModel.Samples")]
    public interface ICalculator
    {
        [OperationContract]
        double Add(double n1, double n2);
        [OperationContract]
        double Subtract(double n1, double n2);
        [OperationContract]
        double Multiply(double n1, double n2);
        [OperationContract]
        double Divide(double n1, double n2);
    }

    // Implement the ICalculator service contract in a service class.
    public class CalculatorService : ICalculator
    {
        // Implement the ICalculator methods.
        public double Add(double n1, double n2)
        {
            double result = n1 + n2;
            return result;
        }

        public double Subtract(double n1, double n2)
        {
            double result = n1 - n2;
            return result;
        }

        public double Multiply(double n1, double n2)
        {
            double result = n1 * n2;
            return result;
        }

        public double Divide(double n1, double n2)
        {
            double result = n1 / n2;
            return result;
        }
    }

    public class CalculatorWindowsService : ServiceBase
    {
        public ServiceHost serviceHost = null;
        public CalculatorWindowsService()
        {
            // Name the Windows Service
            ServiceName = "WCFWindowsServiceSample";
        }

        public static void Main()
        {
            ServiceBase.Run(new CalculatorWindowsService());
        }

        // Start the Windows service.
        protected override void OnStart(string[] args)
        {
            if (serviceHost != null)
            {
                serviceHost.Close();
            }

            // Create a ServiceHost for the CalculatorService type and 
            // provide the base address.
            serviceHost = new ServiceHost(typeof(CalculatorService));

            // Open the ServiceHostBase to create listeners and start 
            // listening for messages.
            serviceHost.Open();
        }

        protected override void OnStop()
        {
            if (serviceHost != null)
            {
                serviceHost.Close();
                serviceHost = null;
            }
        }
    }

    // Provide the ProjectInstaller class which allows 
    // the service to be installed by the Installutil.exe tool
    [RunInstaller(true)]
    public class ProjectInstaller : Installer
    {
        private ServiceProcessInstaller process;
        private ServiceInstaller service;

        public ProjectInstaller()
        {
            process = new ServiceProcessInstaller();
            process.Account = ServiceAccount.LocalSystem;
            service = new ServiceInstaller();
            service.ServiceName = "WCFWindowsServiceSample";
            Installers.Add(process);
            Installers.Add(service);
        }
    }
}

谁能指出我做错了什么？

Answer 1

确保以管理员身份运行命令提示符，否则您将没有足够的权限使用 installutil 安装该服务，您将看到以下消息：

The Rollback phase completed successfully.

The transacted install has completed. The installation failed, and the rollback has been performed.

如果您运行作为管理员，您将看到以下消息：

The Commit phase completed successfully.

The transacted install has completed.

完成后，您应该能够在 services.msc

中看到 "WCFWindowsServiceSample"
