C#获取电脑硬件信息（CPU ID、主板ID、硬盘ID、BIOS编号）

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。
