Question

我有一个使用WMIC（以及C＃）调用SetBiosSetting方法的问题

wmic / namespace：\ root \ wmi path Lenovo_SetBiosSetting call SetBiosSetting“SecurityChip，Active”

wmic / namespace：\ root \ wmi path Lenovo_SetBiosSetting call SetBiosSetting SecurityChip，Active

wmic / namespace：\ root \ wmi path Lenovo_SetBiosSetting call SetBiosSetting（“SecurityChip，Active”）

表示“参数数量无效”。错误，但为什么？

Lenovo BIOS部署指南：http://download.lenovo.com/ibmdl/pub/pc/pccbbs/thinkcentre_pdf/hrdeploy_en.pdf

任何想法？我不能使用VBS或PowerShell ......

谢谢，马丁

在C＃中尝试：

        ManagementScope scope = new ManagementScope(@"\\.\root\wmi");


        //
        // Make change(s)
        //
        SelectQuery queryRead = new SelectQuery("SELECT * from Lenovo_SetBiosSetting");
        using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, queryRead))
        {
            using (ManagementObjectCollection queryCollection = searcher.Get())
            {
                foreach (ManagementObject queryItem in queryCollection)
                {
                    ManagementBaseObject inParams = queryItem.GetMethodParameters("SetBiosSetting");
                    inParams["parameter"] = "WakeOnLAN,Disable";

                    ManagementBaseObject outParams = queryItem.InvokeMethod("SetBiosSetting", inParams, null);
                    string result = outParams["return"] as string; // "Success"
                }
            }
        }


        //
        // Commit to BIOS
        //
        queryRead = new SelectQuery("SELECT * from Lenovo_SaveBiosSettings");
        using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, queryRead))
        {
            using (ManagementObjectCollection queryCollection = searcher.Get())
            {
                foreach (ManagementObject queryItem in queryCollection)
                {
                    ManagementBaseObject inParams = queryItem.GetMethodParameters("SaveBiosSettings");
                    inParams["parameter"] = "";

                    ManagementBaseObject outParams = queryItem.InvokeMethod("SaveBiosSettings", inParams, null);
                    string result = outParams["return"] as string; // "Success"
                }
            }
        }

PowerShell就是：

(gwmi -class Lenovo_SetBiosSetting -namespace root\wmi).SetBiosSetting("WakeOnLAN,Disable")

我到达这篇文章试图找到一种方法来使用WMIC来获取Lenovo_BiosSetting类中的所有对象。你的语法让我走上正轨。我不得不将你的WMIC查询更改为：

wmic /namespace:\\root\wmi path Lenovo_BiosSetting get
