WMI使用集锦
转载：http://singlepine.cnblogs.com/articles/299457.html
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;
3.示例代码
#region 1.如何用WMI获得指定磁盘的容量 private string DriveType(string type) { string rtntype=""; switch (type) { case "1": rtntype="Not Type"; break; case "2": rtntype="Floppy disk"; break; case "3": rtntype="Hard disk"; break; case "4": rtntype="Removable drive or network drive"; break; case "5": rtntype="CD-ROM"; break; case "6": rtntype="RAM disk"; break; default : break; } return rtntype; } private void Button1_Click(object sender, System.EventArgs e) { SelectQuery query=new SelectQuery("Select * From Win32_LogicalDisk"); ManagementObjectSearcher searcher=new ManagementObjectSearcher(query); foreach(ManagementBaseObject disk in searcher.Get()) { Response.Write(disk["Name"] +" "+DriveType(disk["DriveType"].ToString()) + " " + disk["VolumeName"]+"<br>"); } } #endregion #region 2.如何用WMI获得指定磁盘的容量 private void Button2_Click(object sender, System.EventArgs e) { ManagementObject disk = new ManagementObject("win32_logicaldisk.deviceid=\"c:\""); disk.Get(); Response.Write("Logical Disk Size = " + disk["Size"] + " bytes"); } #endregion #region 3.如何列出机器中所有的共享资源 private void Button3_Click(object sender, System.EventArgs e) { ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_share"); foreach (ManagementObject share in searcher.Get()) { Response.Write(share.GetText(TextFormat.Mof)); } } #endregion #region 4.怎样写程控制让系统中的某个文件夹共享或取消共享 private void Button4_Click(object sender, System.EventArgs e) { /*首先，这需要以有相应权限的用户登录系统才行 将 object[] obj = {"C:\\Temp","我的共享",0,10,"Dot Net 实现的共享",""}; 改为 object[] obj = {"C:\\Temp","我的共享",0,null,"Dot Net 实现的共享",""}; 就可以实现授权给最多用户了。 */ ManagementClass _class = new ManagementClass(new ManagementPath("Win32_Share")); object[] obj = {"C:\\Temp","我的共享",0,10,"Dot Net 实现的共享",""}; _class.InvokeMethod("create",obj); } #endregion #region 5.如何获得系统服务的运行状态 private void Button5_Click(object sender, System.EventArgs e) { string[] lvData = new string[4]; ManagementObjectSearcher searcher =new ManagementObjectSearcher("SELECT * FROM Win32_Service"); foreach (ManagementObject mo in searcher.Get()) { lvData[0] = mo["Name"].ToString(); lvData[1] = mo["StartMode"].ToString(); if (mo["Started"].Equals(true)) lvData[2] = "Started"; else lvData[2] = "Stop"; lvData[3] = mo["StartName"].ToString(); Response.Write(lvData[0]+lvData[1]+lvData[2]+lvData[3]); } } #endregion #region 6.通过WMI修改IP，而实现不用重新启动 private void Button6_Click(object sender, System.EventArgs e) { ReportIP(); // SwitchToDHCP(); SwitchToprivate(); Thread.Sleep( 5000 ); ReportIP(); Response.Write( "end." ); } private void SwitchToDHCP() { ManagementBaseObject inPar = null; ManagementBaseObject outPar = null; ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration"); ManagementObjectCollection moc = mc.GetInstances(); foreach( ManagementObject mo in moc ) { if( !
