C#获取电脑硬件信息

获取CPU编号：
view plaincopy to clipboardprint?
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; 
            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：
view plaincopy to clipboardprint?
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; 
            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：
view plaincopy to clipboardprint?
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：
view plaincopy to clipboardprint?
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; 
            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：

view plaincopy to clipboardprint?
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============＝＝＝＝＝＝＝＝＝＝＝";  
}
