C#獲取電腦硬體資訊（CPU ID、主機板ID、硬碟ID、BIOS編號）
最近學習過程中，想到提取系統硬體資訊做一些驗證，故而對網上提到的利用.NET System.Management類獲取硬體資訊做了進一步的學習、驗證。驗證是分別在4臺電腦，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(相容機)；
- 獲取CPU編號：
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
- 獲取主機板編號：
ManagementObjectCollection moc = mc.GetInstances();
string strID = null ;
foreach( ManagementObject mo in moc )
{
strID = mo.Properties["SerialNumber"].Value.ToString();
break;
}
textBox1.Text += "主機板 ID:" + strID;
返回結果：
電腦1：主機板 ID:
電腦2：主機板 ID:CN24401483
電腦3：主機板 ID:AZF241001101
電腦4：主機板 ID:
- 獲取硬碟編號：
ManagementClass mc = new ManagementClass("Win32_PhysicalMedia");
//網上有提到，用Win32_DiskDrive，但是用Win32_DiskDrive獲得的硬碟資訊中並不包含SerialNumber屬性。
ManagementObjectCollection moc = mc.GetInstances();
string strID = null ;
foreach( ManagementObject mo in moc )
{
strID = mo.Properties["SerialNumber"].Value.ToString();
break;
}
textBox1.Text += "硬碟 ID:" + strID;
ManagementClass mc = new ManagementClass("Win32_PhysicalMedia");
//網上有提到，用Win32_DiskDrive，但是用Win32_DiskDrive獲得的硬碟資訊中並不包含SerialNumber屬性。
ManagementObjectCollection moc = mc.GetInstances();
string strID = null ;
foreach( ManagementObject mo in moc )
{
strID = mo.Properties["SerialNumber"].Value.ToString();
break;
}
textBox1.Text += "硬碟 ID:" + strID;
返回結果：
電腦1：硬碟 ID:4833395344463658202020202020202020202020
電腦2：硬碟 ID:WD-WMAJD1092385
電腦3：硬碟 ID:4a353756354d5939202020202020202020202020
電腦4：硬碟 ID:0637J2FW508014
- 獲取BIOS編號：
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欄位就不包含CPU編號資訊。
通過Win32_BaseBoard獲取主機板資訊，但不是所有的主機板都有編號，或者說不是能獲取所有系統主機板的編號。
通過Win32_PhysicalMedia獲取硬碟編號應該沒有問題。但網上說可以通過Win32_DiskDrive獲取，其實所得資訊根本不包含SerialNumber。
通過Win32_BIOS獲取BIOS資訊，基本和獲取主機板資訊差不多。就是說：不是所有的主機板BIOS資訊都有編號。
另外，可以將通過以上各欄位所得資訊輸出，逐個檢視所有資訊 屬性和對應的值。程式碼如下：
ManagementClass mc = new ManagementClass("Win32_Processor");
ManagementObjectCollection moc = mc.GetInstances();
foreach( ManagementObject mo in moc )
{
textBox1.Text += "/r/n============CUP資訊＝＝＝＝＝＝＝＝＝＝＝";
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資訊＝＝＝＝＝＝＝＝＝＝＝";
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============＝＝＝＝＝＝＝＝＝＝＝";
}
