最近学习过程中，想到提取系统硬件信息做一些验证，故而对网上提到的利用.NET System.Management类获取硬件信息做了进一步的学习、验证。验证是分别在4台电脑，XP SP3系统中进行，特将验证过程记录于此。
说明：
电脑1(联想品牌电脑)；
电脑2(HP品牌电脑)；
电脑3(联想品牌电脑)；
电脑4(兼容机)；
- 获取CPU编号
ManagementClass mc = new ManagementClass("Win32_Processor"); ManagementObjectCollection moc = mc.GetInstances(); string strID = null ; foreach( ManagementObject mo in moc ) { strID = mo.Properties["ProcessorId"].Value.ToString(); break; } textBox1.Text += "CPU ID:" + strID;
返回结果：
电脑1：CPU ID:BFEBFBFF00000F27
电脑2：CPU ID:BFEBFBFF00000F27
电脑3：CPU ID:BFEBFBFF00000F29
电脑4：CPU ID:BFEBFBFF00000F29
- 获取主板编号：
ManagementClass mc = new ManagementClass("Win32_BaseBoard"); ManagementObjectCollection moc = mc.GetInstances(); string strID = null ; foreach( ManagementObject mo in moc ) { strID = mo.Properties["SerialNumber"].Value.ToString(); break; } textBox1.Text += "主板 ID:" + strID;
返回结果：
电脑1：主板 ID:
电脑2：主板 ID:CN24401483
电脑3：主板 ID:AZF241001101
电脑4：主板 ID:
- 获取硬盘编号：
ManagementClass mc = new ManagementClass("Win32_PhysicalMedia"); //网上有提到，用Win32_DiskDrive，但是用Win32_DiskDrive获得的硬盘信息中并不包含SerialNumber属性。 ManagementObjectCollection moc = mc.GetInstances(); string strID = null ; foreach( ManagementObject mo in moc ) { strID = mo.Properties["SerialNumber"].Value.ToString(); break; } textBox1.Text += "硬盘 ID:" + strID; ManagementClass mc = new ManagementClass("Win32_PhysicalMedia"); //网上有提到，用Win32_DiskDrive，但是用Win32_DiskDrive获得的硬盘信息中并不包含SerialNumber属性。 ManagementObjectCollection moc = mc.GetInstances(); string strID = null ; foreach( ManagementObject mo in moc ) { strID = mo.Properties["SerialNumber"].Value.ToString(); break; } textBox1.Text += "硬盘 ID:" + strID;
返回结果：
电脑1：硬盘 ID:4833395344463658202020202020202020202020
电脑2：硬盘 ID:WD-WMAJD1092385
电脑3：硬盘 ID:4a353756354d5939202020202020202020202020
电脑4：硬盘 ID:0637J2FW508014
- 获取BIOS编号：
ManagementClass mc = new ManagementClass("Win32_BIOS"); ManagementObjectCollection moc = mc.GetInstances(); string strID = null ; foreach( ManagementObject mo in moc ) { strID = mo.Properties["SerialNumber"].Value.ToString(); break; } textBox1.Text += "BIOS ID:" + strID;
返回结果：
电脑1：BIOS ID:
电脑2：BIOS ID:CN24401483
电脑3：BIOS ID:
电脑4：BIOS ID:
总结：
由以上各步看出，通过Win32_Processor获取CPUID不正确，或者说Win32_Processor字段就不包含CPU编号信息。
通过Win32_BaseBoard获取主板信息，但不是所有的主板都有编号，或者说不是能获取所有系统主板的编号。
通过Win32_PhysicalMedia获取硬盘编号应该没有问题。但网上说可以通过Win32_DiskDrive获取，其实所得信息根本不包含SerialNumber。
通过Win32_BIOS获取BIOS信息，基本和获取主板信息差不多。就是说：不是所有的主板BIOS信息都有编号。
另外，可以将通过以上各字段所得信息输出，逐个查看所有信息 属性和对应的值。代码如下：
ManagementClass mc = new ManagementClass("Win32_Processor"); ManagementObjectCollection moc = mc.GetInstances(); foreach( ManagementObject mo in moc ) { textBox1.Text += "/r/n============CUP信息＝＝＝＝＝＝＝＝＝＝＝"; foreach (PropertyData pd in mo.Properties) { textBox1.Text += "/r/n" + pd.Name + "/t"; if (pd.Value != null) { textBox1.Text += pd.Value.ToString(); } } textBox1.Text += "/r/n/r/n============＝＝＝＝＝＝＝＝＝＝＝"; } ManagementClass mc = new ManagementClass("Win32_Processor"); ManagementObjectCollection moc = mc.GetInstances(); foreach( ManagementObject mo in moc ) { textBox1.Text += "/r/n============CUP信息＝＝＝＝＝＝＝＝＝＝＝"; foreach (PropertyData pd in mo.Properties) { textBox1.Text += "/r/n" + pd.Name + "/t"; if (pd.Value != null) { textBox1.Text += pd.Value.ToString(); } } textBox1.Text += "/r/n/r/n============＝＝＝＝＝＝＝＝＝＝＝"; }

引用楼主的代码：
//定义DLL文件名，此文件路径要加到系统Path中
private const string _fileDll = @"CPUID_Util.dll";
//GetCPUID是 dll里面的一个方法
private const string _FountionName = @"GetCPUID";
[DllImport(_fileDll, EntryPoint = _FountionName, CharSet = CharSet.Unicode, CallingConvention = CallingConvention.StdCall)]
//C#中的申明
public static extern string GetCPUID(string id);
回复
//声明一个stringBuilder类型字符串
StringBuilder strcpu=new StringBuilder();
//将strcpu带入函数中
GetCPUID(strcpu);
//此时的strcpu已经是cpuid了 Console.writeLine(strcpu);
==================================
多核系统中每个处理器的ID是不同的，在哪个处理器上执行得到的就是哪个处理器的ID，获取ID之前可以用SetThreadAffinityMask指定在哪个处理器上执行，这样才能确保每次得到相同的结果。
