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============＝＝＝＝＝＝＝＝＝＝＝";

==================================
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。
