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