winform 读取PC主板序列号

1.引入命名空间：using System.Management;

2.代码实现如下：

public string GeSerialNumber(){            try            {                ManagementObject m_objDisk = new ManagementObject("win32_logicaldisk.deviceid=\"c:\"");                string strSN = (string)m_objDisk.GetPropertyValue("VolumeSerialNumber");                return strSN;            }            catch (Exception)            {                MessageBox.Show("读取失败！");                return "";            }}
