C#中的ManagementClass類(lèi)和獲取硬件的信息的用法
文章來(lái)源：365jz.com 點(diǎn)擊數(shù)：9757 更新時(shí)間：2018-06-07 10:41 參與評(píng)論
在.NET的項(xiàng)目中，有時(shí)候需要獲取計(jì)算機(jī)的硬件的相關(guān)信息，在C#語(yǔ)言中需要利用ManagementClass這個(gè)類(lèi)來(lái)進(jìn)行相關(guān)操作。
現(xiàn)在先來(lái)介紹一下ManagementClass類(lèi)，首先看一下類(lèi)的繼承結(jié)構(gòu)：
現(xiàn)在看一下MSDN對(duì)ManagementClass類(lèi)的解釋?zhuān)瑢?duì)表示一個(gè)通用信息模型 (CIM) 管理類(lèi)。 管理類(lèi)是 WMI 類(lèi)，如 Win32_LogicalDisk, ，該類(lèi)型可表示一個(gè)磁盤(pán)驅(qū)動(dòng)器，并 Win32_Process, ，它表示的進(jìn)程 Notepad.exe 等。 此類(lèi)的成員可以訪問(wèn) WMI 數(shù)據(jù)，使用一個(gè)特定的 WMI 類(lèi)路徑。
一. 接下來(lái)我們來(lái)看一下ManagementClass類(lèi)中一些較為常用的方法的源碼：
1.GetInstances（）：此方法存在四個(gè)重載
2.Get()：
3.GetSubclasses（）：此方法存在四個(gè)重載版本
C# 提供了ManagementClass類(lèi)來(lái)獲取本機(jī)的一些基本信息，比如CPU的個(gè)數(shù)，CPU的頻率，網(wǎng)卡的MAC，內(nèi)存的大小，硬盤(pán)的大小等。
獲取本機(jī)MAC地址：
/// <summary>
/// 獲取本機(jī)的MAC地址
/// </summary>
/// <returns></returns>
public static string GetMACString()
{
ManagementClass mAdapter = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection mo = mAdapter.GetInstances();
foreach (ManagementBaseObject m in mo)
{
if ((bool)m["IpEnabled"] == true)
{
return m["MacAddress"].ToString();
}
}
mo.Dispose();
return null;
}獲取本機(jī)CPU的個(gè)數(shù)：
/// <summary>
/// 獲取CPU的個(gè)數(shù)
/// </summary>
/// <returns></returns>
public static int GetCpuCount()
{
try
{
using (ManagementClass mCpu = new ManagementClass("Win32_Processor"))
{
ManagementObjectCollection cpus = mCpu.GetInstances();
return cpus.Count;
}
}
catch
{
}
return -1;
}獲取本機(jī)CPU的頻率
/// <summary>
/// 獲取CPU的頻率 這里之所以使用string類(lèi)型的數(shù)組，主要是因?yàn)閏pu的多核
/// </summary>
/// <returns></returns>
public static string[] GetCpuMHZ()
{
ManagementClass mc = new ManagementClass("Win32_Processor");
ManagementObjectCollection cpus = mc.GetInstances();
string[] mHz = new string[cpus.Count];
int c = 0;
ManagementObjectSearcher mySearch = new ManagementObjectSearcher("select * from Win32_Processor");
foreach (ManagementObject mo in mySearch.Get())
{
mHz[c] = mo.Properties["CurrentClockSpeed"].Value.ToString();
c++;
}
mc.Dispose();
mySearch.Dispose();
return mHz;
}獲取本機(jī)硬盤(pán)的大小
/// <summary>
/// 獲取硬盤(pán)的大小
/// </summary>
/// <returns></returns>
public static string GetSizeOfDisk()
{
ManagementClass mc = new ManagementClass("Win32_DiskDrive");
ManagementObjectCollection moj = mc.GetInstances();
foreach (ManagementObject m in moj)
{
return m.Properties["Size"].Value.ToString();
}
return "-1";
}
獲取本機(jī)內(nèi)存的大?。?/p>
/// <summary>
/// 獲取內(nèi)存的大小
/// </summary>
/// <returns></returns>
public static string GetSizeOfMemery()
{
ManagementClass mc = new ManagementClass("Win32_OperatingSystem");
ManagementObjectCollection moc = mc.GetInstances();
double sizeAll = 0.0;
foreach (ManagementObject m in moc)
{
if (m.Properties["TotalVisibleMemorySize"].Value != null)
{
sizeAll += Convert.ToDouble(m.Properties["TotalVisibleMemorySize"].Value.ToString());
}
}
mc = null;
moc.Dispose();
return sizeAll.ToString();
}本程序是使用VS2005編寫(xiě)的，可運(yùn)行。
ManageMentClass 對(duì)象被實(shí)例化時(shí)，根據(jù)初始化參數(shù)的不同能夠獲取不同的本地信息："Win32_NetworkAdapterConfiguration" 獲取本機(jī)網(wǎng)絡(luò)適配器對(duì)象。據(jù)此可以獲取網(wǎng)絡(luò)地址等。"Win32_DiskDiver" 獲取本機(jī)硬盤(pán)的相關(guān)信息，"Win32_Processor" 獲取本機(jī)CPU相關(guān)的信息。"Win32_OperatingSystem" 獲取內(nèi)存等相關(guān)信息。
