在Windows服務中使用的IIS中承載的WCF服務的調用方法，但服務未啓動

Question

我是.net和WCF的新手。所以如果這個代碼或者這個問題看起來很傻，請和我一起裸照。 您能否請您指教爲什麼我無法啓動Windows服務。 一旦我開始它立即停止給我的錯誤，沒有工作要做。

下面是代碼：

namespace BulkEmailWindowsService 
{ 
    public class EmailService : ServiceBase 
    {  
     public ServiceHost serviceHost = null; 

     public EmailService() 
     { 
      // Name the Windows Service 
      ServiceName = "WCFWindowsBulkEmailService"; 
     } 

     public static void Main() 
     { 
      ServiceBase.Run(new EmailService()); //-------- Stops right here.. 
     } 


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

      try 
      { 
       Console.WriteLine("Testing 1"); 
       System.Diagnostics.Debugger.Break(); 
       serviceHost = new ServiceHost(typeof(TestBulkEmailService.IBulkEmailService)); 

       serviceHost.Open(); 

       Console.WriteLine("Testing 1"); 
       string logBaseDirectory = "C:\\BulkEmailPrototype\\BulkEmailWindowsService\\BulkEmailWindowsService\\Logs\\BulkEmailWindowsService"; 
       int loggingLevel = int.Parse("5"); 
       int maximumLogFileSize = int.Parse("2"); 
       AppLogger.TraceInfo("Initialization(): Reading configuration settings from config file..."); 
       AppLogger.Init(logBaseDirectory, 0, loggingLevel, "WCFBulkEmail.log", maximumLogFileSize); 
       AppLogger.TraceInfo("Bulk Email Processing Service is starting...."); 

       using (BulkEmailWindowsService.TestBulkEmailService.BulkEmailServiceClient wfc1 = new BulkEmailWindowsService.TestBulkEmailService.BulkEmailServiceClient()) 
       { 
        try 
        { 
         AppLogger.TraceInfo("Database and Email Processing starting...."); 
         BulkEmailDTOList result1 = new BulkEmailDTOList(); 
         result1 = wfc1.GetBulkEmailInfo(1); 
         AppLogger.TraceInfo("Database and Email Processing done...."); 
        } 
        catch 
        { 
         AppLogger.TraceInfo("Error in processing Database and Email...."); 
        } 

       } 

       serviceHost.Close(); 
       serviceHost = null; 
      } 
      catch (Exception ex) 
      { 
       // Log the exception. 
       Console.WriteLine("Error in ONStart "); 
       AppLogger.TraceInfo("Error in OnStart of Bulk Email Processing Service...."); 
      } 

     } 

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

    } 
} 

這裏是我的app.config文件：

<system.serviceModel> 
    <bindings> 
     <basicHttpBinding> 
     <binding name="BasicHttpBinding_IBulkEmailService" closeTimeout="00:01:00" 
      openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" 
      allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" 
      maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" 
      messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" 
      useDefaultWebProxy="true"> 
      <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" 
      maxBytesPerRead="4096" maxNameTableCharCount="16384" /> 
      <security mode="TransportCredentialOnly"> 
      <transport clientCredentialType="Windows" proxyCredentialType="None" 
       realm="" /> 
      <message clientCredentialType="UserName" algorithmSuite="Default" /> 
      </security> 
     </binding> 
     </basicHttpBinding> 
    </bindings> 
    <client> 
     <endpoint address="http://localhost/TestBulkEmailService/TestBulkEmailService.svc/BulkEmailService" 
     binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IBulkEmailService" 
     contract="TestBulkEmailService.IBulkEmailService" name="BasicHttpBinding_IBulkEmailService" /> 
    </client> 
    </system.serviceModel> 
    <startup> 
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/> 
    </startup> 
</configuration> 

請注意，在IIS上承載的WCF服務運行正常，我用它測試一個Web App客戶端。由於我需要不斷自行運行此服務（從db發送一堆行的電子郵件），因此我試圖將它放入Windows服務中，並使用「啓動」和「停止」。如果你知道任何其他方法更簡單，並可以做同樣的事情，請讓我知道。

這是我在我的安裝程序

namespace BulkEmailWindowsService 
{ 

    // 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 = "WCFWindowsBulkEmailService"; 
     Installers.Add(process); 
     Installers.Add(service); 
    } 
    } 
} 

因此，這是不正確的？我很困惑主要會在哪裏。

試試這個在你的主要方法。

private static void Main() 
{ 
    try 
    { 
     ServiceBase[] ServicesToRun; 
     ServicesToRun = new ServiceBase[] 
     { 
      new WindowsService() 
     }; 
     ServiceBase.Run(ServicesToRun); 
    } 
    catch (Exception ex) 
    { 
     Logger.Error(ex.Message)); // if you have a logger? 
    } 
} 

窗口服務的實施應該是這個樣子：

public partial class WindowsService : ServiceBase 
{ 
    internal static ServiceHost myServiceHost = null; 

    public WindowsService() 
    { 
     InitializeComponent(); 
    } 

    protected override void OnStart(string[] args) 
    { 
     if (myServiceHost != null) 
     { 
      myServiceHost.Close(); 
     } 
     myServiceHost = new ServiceHost(typeof (EmailService)); 
     myServiceHost.Open(); 
    } 

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

祝你好運！
