1、 什么是WMI 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(wù)，可以管理遠程計算機（當(dāng)然你必須要擁有足夠的權(quán)限），比如：重啟，關(guān)機，關(guān)閉進程，創(chuàng)建進程等。 2、 如何用WMI獲得本地磁盤的信息？ 首先要在VS.NET中創(chuàng)建一個項目，然后在添加引用中引用一個.net的裝配件：System.Management.dll,這樣你的項目才能使用WMI。代碼如下： using System; using System.Management;
class Sample_ManagementObject { public static int Main(string[] args) { SelectQuery query=new SelectQuery("Select * From Win32_LogicalDisk"); ManagementObjectSearcher searcher=new ManagementObjectSearcher(query); foreach(ManagementBaseObject disk in searcher.Get()) { Console.WriteLine("/r/n"+disk["Name"] +" "+disk["DriveType"] + " " + disk["VolumeName"]); }
Console.ReadLine();
return 0;
}
}
disk["DriveType"] 的返回值意義如下:
1 No type 2 Floppy disk 3 Hard disk 4 Removable drive or network drive 5 CD-ROM 6 RAM disk
3、如何用WMI獲得指定磁盤的容量？ using System; using System.Management;
// This example demonstrates reading a property of a ManagementObject. class Sample_ManagementObject { public static int Main(string[] args) { ManagementObject disk = new ManagementObject( "win32_logicaldisk.deviceid=/"c:/""); disk.Get(); Console.WriteLine("Logical Disk Size = " + disk["Size"] + " bytes"); Console.ReadLine(); return 0; } }
4、 如何列出機器中所有的共享資源？ using System; using System.Management;
class TestApp { [STAThread] static void Main() { ManagementObjectSearcher searcher = new ManagementObjectSearcher( "SELECT * FROM Win32_share"); foreach (ManagementObject share in searcher.Get()) { Console.WriteLine(share.GetText(TextFormat.Mof)); } }
} 別忘記在引用中把System.Management添加進來。
5、 怎樣寫程控制讓系統(tǒng)中的某個文件夾共享或取消共享.？ 首先，這需要以有相應(yīng)權(quán)限的用戶登錄系統(tǒng)才行。然后，試試下面的代碼： using System; using System.Management;
class CreateShare { public static void Main(string[] args) { ManagementClass _class = new ManagementClass(new ManagementPath("Win32_Share"));
object[] obj = {"C://Temp","我的共享",0,10,"Dot Net 實現(xiàn)的共享",""};
_class.InvokeMethod("create",obj); } } 將 object[] obj = {"C://Temp","我的共享",0,10,"Dot Net 實現(xiàn)的共享",""}; 改為 object[] obj = {"C://Temp","我的共享",0,null,"Dot Net 實現(xiàn)的共享",""}; 就可以實現(xiàn)授權(quán)給最多用戶了。
static void ReportIP() { Console.WriteLine( "****** Current IP addresses:" ); ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration"); ManagementObjectCollection moc = mc.GetInstances(); foreach( ManagementObject mo in moc ) { if( ! (bool) mo[ "IPEnabled" ] ) continue;
Console.WriteLine( " Addresses :" ); foreach(string sad in addresses) Console.WriteLine( "/t'{0}'", sad );
Console.WriteLine( " Subnets :" ); foreach(string sub in subnets ) Console.WriteLine( "/t'{0}'", sub ); } } } }
8、 如何利用WMI遠程重啟遠程計算機？ using System; using System.Management; namespace WMI3 { /// <summary> /// Summary description for Class1. /// </summary> class Class1 { static void Main(string[] args) { Console.WriteLine("Computer details retrieved using Windows Management Instrumentation (WMI)"); Console.WriteLine("mailto:Written%2002/01/02%20By%20John%20O'Donnell%20-%20csharpconsulting@hotmail.com"); Console.WriteLine("======================================== ================================="); //連接遠程計算機 ConnectionOptions co = new ConnectionOptions(); co.Username = "john"; co.Password = "john"; System.Management.ManagementScope ms = new System.Management.ManagementScope("http:////192.168.1.2//root//cimv2", co); //查詢遠程計算機 System.Management.ObjectQuery oq = new System.Management.ObjectQuery("SELECT * FROM Win32_OperatingSystem");
ManagementObjectSearcher query1 = new ManagementObjectSearcher(ms,oq); ManagementObjectCollection queryCollection1 = query1.Get(); foreach( ManagementObject mo in queryCollection1 ) { string[] ss={""}; mo.InvokeMethod("Reboot",ss); Console.WriteLine(mo.ToString()); } } } }
9、 利用WMI創(chuàng)建一個新的進程？ using System; using System.Management;
// This sample demonstrates invoking a WMI method using parameter objects public class InvokeMethod { public static void Main() {
//Get the object on which the method will be invoked ManagementClass processClass = new ManagementClass("Win32_Process");
//Get an input parameters object for this method ManagementBaseObject inParams = processClass.GetMethodParameters("Create");
//Fill in input parameter values inParams["CommandLine"] = "calc.exe";
//Execute the method ManagementBaseObject outParams = processClass.InvokeMethod ("Create", inParams, null);
//Display results //Note: The return code of the method is provided in the "returnvalue" property of the outParams object Console.WriteLine("Creation of calculator process returned: " + outParams["returnvalue"]); Console.WriteLine("Process ID: " + outParams["processId"]); } }
10、 如何通過WMI終止一個進程？ using System; using System.Management;
// This example demonstrates how to stop a system service. class Sample_InvokeMethodOptions { public static int Main(string[] args) { ManagementObject service = new ManagementObject("win32_service=/"winmgmt/""); InvokeMethodOptions options = new InvokeMethodOptions(); options.Timeout = new TimeSpan(0,0,0,5);
SELECT MACAddress FROM Win32_NetworkAdapter WHERE ((MACAddress Is Not NULL) AND (Manufacturer <> 'Microsoft'))
結(jié)果：08:00:46:63:FF:8C
CPU的系列號
Select ProcessorId From Win32_Processor
結(jié)果：3FEBF9FF00000F24
主板的系列號
Select SerialNumber From Win32_BIOS
結(jié)果：28362630-3700521 獲取硬盤ID String HDid; ManagementClass cimobject = new ManagementClass("Win32_DiskDrive"); ManagementObjectCollection moc = cimobject.GetInstances(); foreach(ManagementObject mo in moc) { HDid = (string)mo.Properties["Model"].value;
MessageBox.Show(HDid ); }
14、 一個使用WMI后的異常處理的問題 下面是我整理的一段代碼.
ManagementObjectCollection queryCollection1; ConnectionOptions co = new ConnectionOptions(); co.Username = "administrator"; co.Password = "111"; try { System.Management.ManagementScope ms = new System.Management.ManagementScope(@"http://csnt3/root/cimv2", co); System.Management.ObjectQuery oq = new System.Management.ObjectQuery("SELECT * FROM Win32_OperatingSystem"); ManagementObjectSearcher query1 = new ManagementObjectSearcher(ms,oq);
queryCollection1 = query1.Get(); foreach( ManagementObject mo in queryCollection1 ) { string[] ss={""}; mo.InvokeMethod("Reboot",ss); Console.WriteLine(mo.ToString()); } } catch(Exception ee) {
