Question

我尝试在MSDN中使用C＃更新WMI实例，但是我无法让它工作。它解雇了我一个System.Management.ManagementException＆＃39;这没有给我任何答案。如果我做错了，你能告诉我吗？

    public void UpdateInstance(string parametersJSON)
    {
        JavaScriptSerializer serializer = new JavaScriptSerializer();
        object result = serializer.Deserialize(parametersJSON, typeof(object));
        Dictionary<string, object> dic = (Dictionary<string, object>)result;

        PutOptions options = new PutOptions();
        options.Type = PutType.UpdateOnly;

        ManagementObject objHostSetting = new ManagementObject();
        objHostSetting.Scope = new ManagementScope("root\\onguard");
        objHostSetting.Path = new ManagementPath("Lnl_Cardholder.SSNO = '33263085'"); // This is the line that fires the exception

        foreach (KeyValuePair<string, object> value in dic)
        {
            objHostSetting[value.Key] = value.Value.ToString();
        }

        //update the ManagementObject
        objHostSetting.Put(options);
    }

我将代码更改为此代码，现在可以正常运行：

AccessToken accessToken =
   new DefaultFacebookClient().obtainExtendedAccessToken(MY_APP_ID,
     MY_APP_SECRET, MY_ACCESS_TOKEN);

WMI实例更新失败
