WMI 是 Windows Management Instrumentation 。
主要功能是：
访问本地主机的一些信息和服务，可以管理远程计算机，比如：获取磁盘信息，获取磁盘大小，获取网卡地址，获取CPU信息，获取硬盘型号，共享目录，重启，关机，创建进程，关闭进程等。（前提是你拥有足够的权限）呵呵，很强大吧。
使用方法：
很简单，在项目中引用 System.Management.dll 即可。
下面给出部分代码：
private void Page_Load(object sender, System.EventArgs e)
{
TextBox1.Text += getdisk();
TextBox1.Text += getmacaddress();
TextBox1.Text += cpuinfo();
TextBox1.Text += hardinfo();
TextBox1.Text += baseboard();
}
/// <summary>
/// 获取磁盘信息
/// </summary>
/// <returns></returns>
public string getdisk()
{
// disk["DriveType"] 的返回值意义如下:
// 1 No type
// 2 Floppy disk
// 3 Hard disk
// 4 Removable drive or network drive
// 5 CD-ROM
// 6 RAM disk
string a="";
SelectQuery query=new SelectQuery("Select * From Win32_LogicalDisk");
ManagementObjectSearcher searcher=new ManagementObjectSearcher(query);
foreach(ManagementBaseObject disk in searcher.Get())
{
a += (" "+disk["Name"] +" "+disk["DriveType"] + " " + disk["VolumeName"]) + diskinfo(disk["Name"].ToString()) +"n";
}
return a;
}
/// <summary>
/// 获取磁盘大小
/// </summary>
/// <param name="d"></param>
/// <returns></returns>
public string diskinfo(string d)
{
string a="";
ManagementObject disk = new ManagementObject("win32_logicaldisk.deviceid='"+d+"'");
disk.Get();
a = (" " + disk["Size"] + " bytes");
return a;
}
/// <summary>
/// 获取网卡地址
/// </summary>
/// <returns></returns>
public string getmacaddress()
{
string a="";
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = mc.GetInstances();
foreach(ManagementObject mo in moc)
{
if((bool)mo["IPEnabled"] == true)
a = "网卡：" + mo["MacAddress"].ToString() + "n";
mo.Dispose();
}
return a;
}
/// <summary>
/// 获取CPU信息
/// </summary>
/// <returns></returns>
public string cpuinfo()
{
string a="";
ManagementClass mcobject = new ManagementClass("Win32_Processor");
ManagementObjectCollection moc = mcobject.GetInstances();
foreach(ManagementObject mo in moc)
{
a += "CPU：" + mo.Properties["ProcessorId"].Value.ToString() + "n";
}
return a;
}
/// <summary>
/// 获取硬盘型号
/// </summary>
/// <returns></returns>
public string hardinfo()
{
string a="";
ManagementClass mcobject = new ManagementClass("Win32_DiskDrive");
ManagementObjectCollection moc = mcobject.GetInstances();
foreach(ManagementObject mo in moc)
{
a += "硬盘型号：" + mo.Properties["Model"].Value.ToString() + mo.Properties[""].Value.ToString() + "n";
}
return a;
}
public string baseboard()
{
string a="";
SelectQuery query=new SelectQuery("SELECT * FROM Win32_BaseBoard");
ManagementObjectSearcher searcher=new ManagementObjectSearcher(query);
foreach(ManagementBaseObject disk in searcher.Get())
{
a += "主板制造商： "+disk["Manufacturer"] +"n型号： "+disk["Product"] + "n序列号： " + disk["SerialNumber"] +baseinfo() +"n";
}
return a;
}
public string baseinfo()
{
string a="";
SelectQuery query=new SelectQuery("Select SerialNumber From Win32_BIOS");
ManagementObjectSearcher searcher=new ManagementObjectSearcher(query);
foreach(ManagementBaseObject disk in searcher.Get())
{
a = disk["SerialNumber"].ToString();
}
return a;
}
