我正在使用WMI(System.Managment)和C#編寫ASP.Net網站配置軟件。使用WMI和ASP.Net在IIS 7.0中啓動FTp站點時出現「Invalid Class」錯誤
我想在位於局域網某處的「目標服務器」上創建FTP站點,同時在主機上執行代碼。創建FTP後,我無法啓動FTP站點。
所報告的錯誤是「無效類」以下行:
ManagementObject site = new ManagementObject(
new ManagementPath(string.Format(@"IIsFtpServer.Name='MSFTPSVC/{0}'", siteId)), null);
**site.InvokeMethod("Start", null);**
這裏是我的完整功能。
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;
}
在分析代碼,我發現「網站」對象拋出「無效類」的例外,在"site.ClassPath".
我也曾嘗試使用下面的行,但同樣的錯誤是存在的。
ManagementObject site = new ManagementObject(scope,
new ManagementPath(Convert.ToString(
outParameter.Properties["ReturnValue"].Value)), null);
site.InvokeMethod("Start", null);
但FTP站點已創建並且其所有屬性都已設置,但它不通過代碼啓動。可以通過轉到IIS管理器來手動啓動它。
該代碼在IIS 6.0上工作得非常好(因爲我使用的是WMI),我希望它能在IIS 7.0或更高版本上正常運行。
我做錯了什麼,但不知道在哪裏。請幫助。謝謝。
感謝
我自己想到了這個問題,因爲我在錯誤的類上調用函數。必須在服務器類上調用「開始」方法。即IIsWebServer.Start()或IIsFtpServer.Start() – 2010-02-15 09:24:42
