寄宿WCF服务相关实现方法解析

WCF是一款由微软公司研发的.NET Framework 3.5重要组成部件。它的功能优势突出，比如在兼容性，安全性方面尤其突出。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:

寄宿WCF服务步骤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;  
}  
}  
}  
} 

寄宿WCF服务步骤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

寄宿WCF服务步骤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> 

寄宿WCF服务步骤4.利用工具C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\installutil.exe安装windows 服务.installutil.exe winservice.exe

#t#

寄宿WCF服务步骤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.

寄宿WCF服务步骤6.访问wcf服务:http://localhost:8000/service

寄宿WCF服务步骤7.停止wcf服务:net stop WCFWindowsServiceSample

寄宿WCF服务步骤8.卸载windows服务:installutil.exe /u winservice.exe
