在C\#中使用WMI

WMI的功能只适合在微軟的Windows的系統中,它是Windows系統默認情況下開啟的一項服務.它在Windows系統中的功能非常強大.但如果停用了這個服務,那么這种方法就不能正常使用了.  
在學習WMI的時候,由于WMI的類太多了,而且結构不是很清楚,所以個人認為一定要熟悉后,使用起來才方便.在C\#中使用WMI,必須要添加引用"System.Management.dll",然后手動添加using System.Management;

1.調用WMI中的屬性  
一般來說,我們都是通過WQL語句來調用(如例2),但由于C\#中提供了丰富的類庫,所以也有其它的一些方式(如例1)  
示例1:利用ManagementClass  
/// <summary>  
/// 獲取CPU的序列號  
/// </summary>  
/// <returns></returns>  
public string GetCpuID()  
\{  
string info="";  
ManagementClass mc = new ManagementClass("Win32\_Processor");  
ManagementObjectCollection moc=mc.GetInstances();  
foreach(ManagementObject mo in moc)  
\{  
info = mo.Properties\["ProcessorId"\].Value.ToString();  
\}  
moc=null;  
mc=null;  
return info;

\}  
示例2:利用ManagementObjectSearcher  
/// <summary>  
/// 獲取CPU的當前電壓  
/// </summary>  
/// <returns></returns>  
public string GetCpuCurrentVoltage()  
\{  
string info ="";  
ManagementObjectSearcher search = new ManagementObjectSearcher("SELECT \* FROM Win32\_Processor");  
foreach (ManagementObject mo in search.Get())  
\{  
info = mo\["CurrentVoltage"\].ToString();  
\}  
return info;  
\}

2.調用WMI中的方法  
示例1:創建共享  
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);

示例2:終止一個進程  
ManagementObject service = new ManagementObject("win32\_service=/"winmgmt/"");  
InvokeMethodOptions options = new InvokeMethodOptions();  
options.Timeout = new TimeSpan(0,0,0,5);  
ManagementBaseObject outParams = service.InvokeMethod("StopService", null, options);  
Response.Write("Return Status = " + outParams\["Returnvalue"\]);

示例3:創建一個進程  
ManagementClass processClass = new ManagementClass("Win32\_Process");  
ManagementBaseObject inParams = processClass.GetMethodParameters("Create");  
inParams\["CommandLine"\] = "calc.exe";  
ManagementBaseObject outParams = processClass.InvokeMethod ("Create", inParams, null);  
Response.Write("Creation of calculator process returned: " + outParams\["returnvalue"\]);  
Response.Write("Process ID: " + outParams\["processId"\]);

3.遠程調用WMI  
遠程調用WMI,与本地調用的區別就是:必須提供用戶名和密碼  
示例1:  
　 //连接远程计算机  
　　　　　　ConnectionOptions co = new ConnectionOptions();  
　　　　　　co.Username = "john";  
　　　　　　co.Password = "john";  
　　　　　　System.Management.ManagementScope ms = new System.Management.ManagementScope("192.168.1.4//root//cimv2", co);

//查询远程计算机  
　　　　　　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 )  
　　　　　　\{  
　　　　　　　　　　　　Console.WriteLine("Name : " + mo\["name"\].ToString());  
　　　　　　　　　　　　Console.WriteLine("Version : " + mo\["version"\].ToString());  
　　　　　　　　　　　　Console.WriteLine("Manufacturer : " + mo\["Manufacturer"\].ToString());  
　　　　　　　　　　　　Console.WriteLine("Computer Name : " +mo\["csname"\].ToString());  
　　　　　　　　　　　　Console.WriteLine("Windows Directory : " +mo\["WindowsDirectory"\].ToString());  
\}  
示例2:重啟遠程計算机  
//连接远程计算机  
ConnectionOptions co = new ConnectionOptions();  
co.Username = "john";  
co.Password = "john";  
System.Management.ManagementScope ms = new System.Management.ManagementScope("192.168.1.2//root//cimv2", co);  
//查询远程计算机  
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);  
Response.Write(mo.ToString());  
\}
