远程wmi连接c# - 参数错误无效

Question

当我运行以下代码时

ConnectionOptions options = new ConnectionOptions();
        options.EnablePrivileges = true;
        options.Impersonation = ImpersonationLevel.Impersonate;
        options.Authentication = AuthenticationLevel.Packet;
        options.Authority = "ntdlmdomain:InsTIL.com";
        options.Username = "instil" + @"\" + "admin";
        options.Password = "Pwd";

        ManagementScope scope= new ManagementScope(string.Format(@"\\172.16.2.171\root\cimv2"),options);
        scope.Connect();
        if (scope.IsConnected == true)
        {
           Console.WriteLine("Connection Succeeded");
        }
        else
        {
            Console.WriteLine("Connection Failed");
        }


        ObjectQuery query = new ObjectQuery("Select * from win32_operatingsystem");
        ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);

        ManagementObjectCollection querycollection = searcher.Get();
        foreach (ManagementObject mobj in querycollection)
        {
            Console.WriteLine("Computer name: {0}", mobj["csname"]);
            Console.WriteLine("Windows Directory : {0}", mobj["WindowsDirectory"]);
            Console.WriteLine("Operating System: {0}", mobj["Caption"]);
            Console.WriteLine("Version: {0}", mobj["Version"]);
            Console.WriteLine("Manufacturer : {0}", mobj["Manufacturer"]);
        }

我得到以下错误

  Unhandled Exception: System.Management.ManagementException: Invalid parameter
   at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode)
    at System.Management.ManagementScope.InitializeGuts(Object o)
   at System.Management.ManagementScope.Initialize()
  at remote_wmi.Program.Main(String[] args) in E:\.net prep\.net examples\remote wmi\remote wmi\Program.cs:line 21

请帮我理解为什么会发生这种情况.这段代码有什么问题？我们需要在执行此代码之前做任何事情吗？如果是,请说明.

提前致谢.

Answer 1

我做了以下更改,然后我得到了答案.

1)我没有用用户名指定域名. options.Username = "admin";代替 options.Username = "instil" + @"\" + "admin";

2) options.Authority = "ntlmdomain:InsTIL.com";而不是options.Authority = "ntdlmdomain:InsTIL.com";
