C#中使用ManagementClass获取本机信息

C#提供 ManagementClass来对机器的信息进行管理，可以通过设定不同的管理类来获得机器的基本信息。下面给出了一些基本的信息的获取方法，包括获取CPU数目，cpu频率，内存大小，硬盘大小。

private void GetLocalInfo()
{
string cpuCount;
string hdSize;
string memorysize;

//得到CPU信息
ManagementClass mcpu = new ManagementClass("Win32_Processor");
ManagementObjectCollection mncpu = mcpu.GetInstances();
cpuCount = mncpu.Count.ToString();
string[] cpuHz = new string[mncpu.Count];
int count = 0;
ManagementObjectSearcher MySearcher = new ManagementObjectSearcher("SELECT * FROM Win32_Processor");
foreach (ManagementObject MyObject in MySearcher.Get())
{
cpuHz[count] = MyObject.Properties["CurrentClockSpeed"].Value.ToString();
count++;
}
mncpu.Dispose();
mcpu.Dispose();

//得到硬盘信息
ManagementClass mcHD = new ManagementClass("Win32_DiskDrive");
ManagementObjectCollection moHD = mcHD.GetInstances();

foreach (ManagementObject tempob in moHD)
{
hdSize = tempob.Properties["Size"].Value.ToString();
}
moHD.Dispose();
mcHD.Dispose();

//得到内存信息
ManagementClass mcMemory = new ManagementClass("Win32_OperatingSystem");
ManagementObjectCollection mocMemory = mcMemory.GetInstances();

double sizeall = 0;
foreach (ManagementObject mo in mocMemory)
{
if (mo.Properties["TotalVisibleMemorySize"].Value != null)
{
sizeall += double.Parse(mo.Properties["TotalVisibleMemorySize"].Value.ToString());
}
}
memorysize = sizeall.ToString();
mocMemory.Dispose();
mcMemory.Dispose();

}
