wmic - WMIC - 如何使用联想 SetBiosSetting 方法

Question

我有一个使用 WMIC（以及 C#）调用 SetBiosSetting 方法的问题

wmic /namespace:\root\wmi 路径 Lenovo_SetBiosSetting 调用 SetBiosSetting "SecurityChip,Active"

wmic /namespace:\root\wmi 路径 Lenovo_SetBiosSetting 调用 SetBiosSetting SecurityChip,Active

wmic /namespace:\root\wmi 路径 Lenovo_SetBiosSetting 调用 SetBiosSetting ("SecurityChip,Active")

给出“无效的参数数量”。错误，但为什么？

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

任何的想法 ？我不能使用 VBS 或 PowerShell ...

谢谢，马丁

在 C# 中试试这个：

        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"
                }
            }
        }

用于此的 PowerShell 是：

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

我来到这篇文章试图找到一种使用 WMIC 获取Lenovo_BiosSetting类中所有对象的方法。你的语法让我走上了正确的轨道。我不得不将您的 WMIC 查询更改为：

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

（注意双反斜杠）
