WMI使用集锦

發布時間：2023/11/27 生活经验 19 豆豆

生活随笔收集整理的這篇文章主要介紹了 WMI使用集锦小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

1.WMI簡介
WMI是英文Windows?Management?Instrumentation的簡寫，它的功能主要是：訪問本地主機的一些信息和服務，可以管理遠程計算機（當然你必須要擁有足夠的權限），比如：重啟，關機，關閉進程，創建進程等。
2.使用時首先添加System.Management.dll，然后引用

using?System.Management;
using?System.Threading;? 3.示例代碼
3.1 html代碼
