如何在windows服务中寄宿wcf服务的例子

Posted 2023-03-14

参考技术A 在windows服务中寄宿wcf服务,需要继承ServiceBase,此外,还须要继承Installer以安装服务.以下为具体实现步骤:
1.创建文件winservice.cs,输入代码
namespace windowswcfservice

using System.ServiceProcess;
using System.ServiceModel;
using System.Configuration.Install;
using System.Configuration;
using System.ComponentModel;
[ServiceContract(Namespace="http://mysample")]
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);

public class CalculatorService : ICalculator

public double Add(double n1, double n2)

return n1 + n2;

public double Subtract(double n1, double n2)

return n1 - n2;

public double Multiply(double n1, double n2)

return n1 * n2;

public double Divide(double n1, double n2)

return n1 / n2;


[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);


public class WindowsCalculatorService : ServiceBase

public ServiceHost serviceHost = null;
public static void Main()

ServiceBase.Run(new WindowsCalculatorService());

protected override void OnStart(string[] args)

if (serviceHost != null)

serviceHost.Close();

try

serviceHost = new ServiceHost(typeof(CalculatorService));
serviceHost.Open();

catch(System.Exception err)

System.Diagnostics.EventLog.WriteEntry("Application", err.Message);


protected override void OnStop()

if (serviceHost != null)

serviceHost.Close();
serviceHost = null;





2.用csc编译文件winservice.cs
csc /t:exe winservice.cs /r:"C:/WINDOWS/Microsoft.NET/Framework/v3.0/Windows Communication Foundation/System.ServiceModel.dll" /r:C:/WINDOWS/Microsoft.NET/Framework/v2.0.50727/System.ServiceProcess.dll /r:System.Configuration.Install.dll

3.创建winservice.exe.config,内容如下:
<?xml version="1.0"?>
<configuration>
<system.serviceModel>
<services>
<service name="windowswcfservice.CalculatorService" behaviorConfiguration="Metadata" >
<host>
<baseAddresses>
<add baseAddress="http://localhost:8000/service"/>
</baseAddresses>
</host>
<endpoint address="*" binding="wsHttpBinding" contract="windowswcfservice.ICalculator" />
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="Metadata">
<serviceMetadata httpGetEnabled="true" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
4.利用工具C:/WINDOWS/Microsoft.NET/Framework/v2.0.50727/installutil.exe安装windows 服务.
installutil.exe winservice.exe
5.启动服务:net start WCFWindowsServiceSample
如果服务不能启动,可查看事件日志以定位错误.
6.访问wcf服务:http://localhost:8000/service
7.停止wcf服务:net stop WCFWindowsServiceSample
8.卸载windows服务:installutil.exe /u winservice.exe
