最近學習過程中，想到提取系統硬件信息做一些驗證，故而對網上提到的利用.NET System.Management類獲取硬件信息做了進一步的學習、驗證。驗證是分別在4台電腦，XP SP3系統中進行，特將驗證過程記錄於此。
說明：
電腦1(聯想品牌電腦)；
電腦2(HP品牌電腦)；
電腦3(聯想品牌電腦)；
電腦4(兼容機)；
- 獲取CPU編號：
返回結果：
電腦1：CPU ID:BFEBFBFF00000F27
電腦2：CPU ID:BFEBFBFF00000F27
電腦3：CPU ID:BFEBFBFF00000F29
電腦4：CPU ID:BFEBFBFF00000F29
- 獲取主板編號：
返回結果：
電腦1：主板 ID:
電腦2：主板 ID:CN24401483
電腦3：主板 ID:AZF241001101
電腦4：主板 ID:
- 獲取硬盤編號：
ManagementClass mc = new ManagementClass("Win32_PhysicalMedia");
//網上有提到，用Win32_DiskDrive，但是用Win32_DiskDrive獲得的硬盤信息中並不包含SerialNumber屬性。
ManagementObjectCollection moc = mc.GetInstances();
string strID = null ;
foreach( ManagementObject mo in moc )
{
strID = mo.Properties["SerialNumber"].Value.ToString();
break;
}
textBox1.Text += "硬盤 ID:" + strID;
ManagementClass mc = new ManagementClass("Win32_PhysicalMedia");
//網上有提到，用Win32_DiskDrive，但是用Win32_DiskDrive獲得的硬盤信息中並不包含SerialNumber屬性。
ManagementObjectCollection moc = mc.GetInstances();
string strID = null ;
foreach( ManagementObject mo in moc )
{
strID = mo.Properties["SerialNumber"].Value.ToString();
break;
}
textBox1.Text += "硬盤 ID:" + strID;
返回結果：
電腦1：硬盤 ID:4833395344463658202020202020202020202020
電腦2：硬盤 ID:WD-WMAJD1092385
電腦3：硬盤 ID:4a353756354d5939202020202020202020202020
電腦4：硬盤 ID:0637J2FW508014
- 獲取BIOS編號：
返回結果：
電腦1：BIOS ID:
電腦2：BIOS ID:CN24401483
電腦3：BIOS ID:
電腦4：BIOS ID:
總結：
由以上各步看出，通過Win32_Processor獲取CPUID不正確，或者說Win32_Processor字段就不包含CPU編號信息。
通過Win32_BaseBoard獲取主板信息，但不是所有的主板都有編號，或者說不是能獲取所有系統主板的編號。
通過Win32_PhysicalMedia獲取硬盤編號應該沒有問題。但網上說可以通過Win32_DiskDrive獲取，其實所得信息根本不包含SerialNumber。
通過Win32_BIOS獲取BIOS信息，基本和獲取主板信息差不多。就是說：不是所有的主板BIOS信息都有編號。
另外，可以將通過以上各字段所得信息輸出，逐個查看所有信息 屬性和對應的值。代碼如下：

使用方法舉例：
==========
引用樓主的代碼：
//定義DLL文件名，此文件路徑要加到系統Path中
private const string _fileDll = @"CPUID_Util.dll";
//GetCPUID是 dll里面的一個方法
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);
回復
//聲明一個stringBuilder類型字符串
StringBuilder strcpu=new StringBuilder();
//將strcpu帶入函數中
GetCPUID(strcpu);
//此時的strcpu已經是cpuid了 Console.writeLine(strcpu);
==================================
多核系統中每個處理器的ID是不同的，在哪個處理器上執行得到的就是哪個處理器的ID，獲取ID之前可以用SetThreadAffinityMask指定在哪個處理器上執行，這樣才能確保每次得到相同的結果。
