在使用C#操作IIS創(chuàng)建應(yīng)用程序池出現(xiàn)異常：無效索引（Exception from HRESULT:0x80070585）

相關(guān)代碼：

public static string CreateAppPool(string appPoolName, string frameworkVersion, string managedPipelineMode)
{
   DirectoryEntry rootfolder = new DirectoryEntry("IIS://localhost/W3SVC/APPPOOLS");
   try
   {
       DirectoryEntry appPool = rootfolder.Children.Add(appPoolName, "IIsApplicationPool");
       if (appPool.Properties.Contains("AppPoolCommand"))
       {
           appPool.Properties["AppPoolCommand"][0] = "1";
       }
       if (appPool.Properties.Contains("ManagedRuntimeVersion"))
       {
           appPool.Properties["ManagedRuntimeVersion"][0] = "v4.0";
       }
       //以下代碼在WindowsServer2008版本為6.0的系統(tǒng)上會(huì)出現(xiàn)異常：
       //無效索引（Exception from HRESULT:0x80070585）
       //if (appPool.Properties.Contains("AppPoolIdentityType"))
       //{
       //    appPool.Properties["AppPoolIdentityType"][0] = "4";
       //}
       if (appPool.Properties.Contains("Enable32BitAppOnWin64"))
       {
           appPool.Properties["Enable32BitAppOnWin64"][0] = true;
       }
       appPool.CommitChanges();
       return null;
   }
   catch (System.Exception ex)
   {
       LogToFile.Save(ex, "CreateAppPool");
       return ex.Message;
   }
}

將相關(guān)代碼注釋以后，未見對(duì)Web應(yīng)用程序帶來任何影響。
