Question

我正在使用WMI（System.Managment）和C＃开发ASP.Net网站供应软件。

我正在尝试在我位于局域网某处的“目标服务器”上创建FTP站点，同时在我的主机上执行代码。创建后我无法启动FTP站点。

在以下行中报告的错误是“无效的类”：

ManagementObject site = new ManagementObject(
          new ManagementPath(string.Format(@"IIsFtpServer.Name='MSFTPSVC/{0}'", siteId)), null);
        **site.InvokeMethod("Start", null);**

这是我的完整功能。

public static String CreateFtpsite(String serverName,
    String ip,String ServerComment,int AccessFlags,
    String pathToRoot, String hostName, String domainName, int port)
{
    //ConnectionOptions options = new ConnectionOptions();
    //options.Authentication = AuthenticationLevel.Connect;
    //options.EnablePrivileges = true;
    //options.Impersonation = ImpersonationLevel.Impersonate;
    ConnectionOptions options = SetUpAuthorization();
    ManagementScope scope =
       new ManagementScope(string.Format(@"\\{0}\root\MicrosoftIISv2", serverName), options);
    scope.Connect();
    ManagementObject oW3SVC = new ManagementObject(scope,
    new ManagementPath(@"IIsFtpService='MSFTPSVC'"), null);

    ManagementBaseObject[] serverBindings = new ManagementBaseObject[3];
    /*serverBindings[0] = CreateServerBinding(scope, 
                        string.Format("{0}.{1}", hostName, domainName), ip, port);
    */
    serverBindings[0] = CreateServerBinding(scope,
                        string.Format("{0}", hostName, domainName), ip, port);
    serverBindings[1] = CreateServerBinding(scope,
                        string.Format(ip, hostName, domainName), ip, port);
    serverBindings[2] = CreateServerBinding(scope,
                        string.Format("127.0.0.1", hostName, domainName), ip, port);

    ManagementBaseObject inputParameters = oW3SVC.GetMethodParameters("CreateNewSite");

    inputParameters["ServerBindings"] = serverBindings;
    inputParameters["ServerComment"] = ServerComment;
    inputParameters["PathOfRootVirtualDir"] = pathToRoot;

    ManagementBaseObject outParameter =
      oW3SVC.InvokeMethod("CreateNewSite", inputParameters, null);

    string siteId = Convert.ToString(
     outParameter.Properties["ReturnValue"].Value).Replace(
     "IIsFtpServer='MSFTPSVC/", "").Replace("'", "");
    ManagementObject oFtpVirtDir = new ManagementObject(scope,
    new ManagementPath(string.Format(
        @"IIsFtpVirtualDirSetting.Name='MSFTPSVC/{0}/root'", siteId)), null);
    oFtpVirtDir.Properties["AccessFlags"].Value = AccessFlags ;
    oFtpVirtDir.Properties["Path"].Value = pathToRoot;

    ManagementObject oFtpVirtDirProperties = new ManagementObject(scope,
    new ManagementPath(string.Format(@"IIsFtpServerSetting.Name='MSFTPSVC/{0}'", siteId)), null);
    oFtpVirtDirProperties.Properties["AllowAnonymous"].Value  = true;
    oFtpVirtDirProperties.Properties["AnonymousOnly"].Value = true;
    oFtpVirtDirProperties.Properties["AnonymousUserName"].Value = @"DevIIS\Administrator";
    oFtpVirtDirProperties.Properties["AnonymousUserPass"].Value = "Passw0rd";
    oFtpVirtDirProperties.Properties["MaxConnections"].Value = 555;
    oFtpVirtDirProperties.Properties["ServerAutoStart"].Value = true;
    oFtpVirtDirProperties.Properties["UserIsolationMode"].Value = 1;
    oFtpVirtDirProperties.Properties["ConnectionTimeout"].Value = 1234 ;
    oFtpVirtDirProperties.Properties["LogFileTruncateSize"].Value = 54321;
    oFtpVirtDirProperties.Put();

    ManagementObject site = new ManagementObject(
      new ManagementPath(string.Format(@"IIsFtpServer.Name='MSFTPSVC/{0}'", siteId)), null);
    site.InvokeMethod("Start", null); //Error occurs Here (Invalid Class)
    return siteId;
}

public static ConnectionOptions SetUpAuthorization()
    {
        ConnectionOptions options = new ConnectionOptions();

        options.Authentication = AuthenticationLevel.PacketPrivacy;
        options.EnablePrivileges = true;
        options.Impersonation = ImpersonationLevel.Impersonate;
        options.Username = @"DevIIS\Administrator";
        options.Password = "Passw0rd";
        return options;
    }

在分析代码时，我发现“site”对象在"site.ClassPath".

上抛出了“无效类”的异常

我也尝试使用以下行，但同样的错误就在那里。

ManagementObject site = new ManagementObject(scope, 
      new ManagementPath(Convert.ToString(
      outParameter.Properties["ReturnValue"].Value)), null);

        site.InvokeMethod("Start", null);

但是FTP站点已创建且其所有属性都已设置，但它不是通过代码启动的。可以通过转到IIS管理器手动启动它。

代码在IIS 6.0上工作得很好，并且（因为我使用的是WMI）我希望它在IIS 7.0或更高版本上运行正常。

我做错了什么但无法猜到哪里。请帮助。感谢。

Answer 1

在iis7中，它不会在元数据库中创建“MSFTPSVC”文件夹。它将ftpsite放在数据库的网站容器中。所以答案是：使用@“IIsWebService ='W3SVC'”作为管理路径，而不是您正在使用的路径。

Answer 2

我自己想到了这个问题，因为我在错误的班级上调用了这个函数。必须在服务器类上调用“Start”方法。即IIsWebServer.Start（）或IIsFtpServer.Start（）

使用WMI和ASP.Net C＃在IIS 7.0中启动FTp站点时出现“无效类”错误（Windows Server 2008）
