FCL小应用系列------------如何获取网卡等硬件信息

要想获取运行主机的各种配置信息，如网卡MAC地址，IP地址，硬盘分区，硬盘号等等，只要引用System.Management就可以轻松实现这一切。比起VC++的实现简单的多得多。例如获取当前使能的网卡MAC，并显示在列表框控件中：

ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
            ManagementObjectCollection moc = mc.GetInstances();
            foreach (ManagementObject mo in moc)
            {
                if ((bool)mo["IPEnabled"] == true)
                    listBox1.Items.Add ( mo["MacAddress"].ToString());

            }

上述代码,只能获取到激活的网卡，并且网卡必须有连线。要想在网络连线断开的情况下也能获取到MAC，则需要如下代码

ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
            ManagementObjectCollection moc = mc.GetInstances();
            foreach (ManagementObject mo in moc)
            {
                if ((bool)mo["MacAddress"] != null)
                    listBox1.Items.Add ( mo["MacAddress"].ToString());

            }

上述代码，可以获取到断线的网卡MAC，但是不能获取到禁用的网卡MAC。

另外，获取CPU序列号，硬盘序列号的代码如下：

private void GetInfo()  
  {  
   string cpuInfo = "";//cpu序列号  
   ManagementClass cimobject = new ManagementClass("Win32_Processor");  
   ManagementObjectCollection moc = cimobject.GetInstances();  
   foreach(ManagementObject mo in moc)  
   {  
    cpuInfo = mo.Properties["ProcessorId"].Value.ToString();  
    Console.WriteLine ("cpu序列号："+cpuInfo.ToString ());  
   }  
   //获取硬盘ID  
   String HDid;  
   ManagementClass cimobject1 = new ManagementClass("Win32_DiskDrive");  
   ManagementObjectCollection moc1 = cimobject1.GetInstances();  
   foreach(ManagementObject mo in moc1)  
   {  
    HDid = (string)mo.Properties["Model"].Value;  
    Console.WriteLine("硬盘序列号："+HDid.ToString ());  
   }
