WMI使用集锦

1.WMI简介WMI是英文Windows Management Instrumentation的简写运维
强烈推介IDEA2020.2破解激活,IntelliJ IDEA 注册码,2020.2 IDEA 激活码

1.WMI简介
WMI是英文Windows Management Instrumentation的简写,它的功能主要是:访问本地主机的一些信息和服务,可以管理远程计算机(当然你必须要拥有足够的权限),比如:重启,关机,关闭进程,创建进程等。
2.使用时首先添加System.Management.dll,然后引用


using
 System.Management;

using
 System.Threading;
