Wmi ( windows management instrument ) 研究
一、初始化 (1)加入參考System.manegement (2) using System.management
二、首先在連線的部分：
(1)本機：new ManagementClass(path) ex: path = “Win32_Process”
(2)遠端：new ManagementClass(Scope,Path, null)
其中Scope=new managementScope(@\\192.168.1.1\root\cimv2,options)
其中options=new connectionOptions()
且options.Username .password是遠端登入帳密
三、範例：
(1)查本機所有進程
ManagementObjectSearcher mos = new ManagementObjectSearcher(@"\\.\root\CIMV2", "SELECT * FROM Win32_Process");
ManagementObjectCollection moc = mos.Get();
foreach (ManagementObject mo in moc) {
MessageBox.Show(mo.GetText(new TextFormat()));
}
(2)查遠端所有進程
ManagementScope MS_Conn;
System.Management.ConnectionOptions options;
options = new ConnectionOptions();
options.Username = “帳號”;
options.Password = “密碼”;
MS_Conn = new ManagementScope(@"\\" + ip + @"\root\cimv2", options);
MS_Conn.Connect();
ManagementObjectSearcher mos = new ManagementObjectSearcher(MS_Conn, new ObjectQuery("SELECT * FROM Win32_Process"));
ManagementObjectCollection moc = mos.Get();
foreach (ManagementObject mo in moc) {}
*注意幾個地方 若登入的使用者號為本機 則 \\帳號 若有網域的就直接打帳號
*另外 遠端使用Win32_Process類別的Create來執行程式時，會背景執行
*本機程式若要背景執行…相關執行設定請參考Win32_ProcessStartup類別 設定好後可放入Win32_Process開檔時使用 InvokeMethod(“Create”,method參數,win32_processstartup)
