我是靠谱客的博主冷艳毛衣，最近开发中收集的这篇文章主要介绍C#获取电脑硬件信息（CPU ID、主板ID、硬盘ID、BIOS编号），觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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============＝＝＝＝＝＝＝＝＝＝＝";
            }

                    }
                }
            }
            catch
            { }
            return addr.Replace(' ', '0');
        }
    }
}

使用方法举例：

 
  //获取硬盘序列号     
 

   Hardware.HardwareInfo hardwareInfo = new Hardware.HardwareInfo();    
  
string hardDiskID = hardwareInfo.GetHardDiskID();    
  
System.Console.WriteLine(hardDiskID);    
  
   
  
//获取CPU序列号     
  
string cpuID = hardwareInfo.GetCpuID();    
  
System.Console.WriteLine(cpuID);    
  
//获取硬盘序列号Hardware.HardwareInfo hardwareInfo = new Hardware.HardwareInfo();string hardDiskID = hardwareInfo.GetHardDiskID();System.Console.WriteLine(hardDiskID);//获取CPU序列号string cpuID = hardwareInfo.GetCpuID();System.Console.WriteLine(cpuID);    
 
 
==========
 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);
