C#通过WMI获取硬件信息

有时候需要得到硬件信息绑定用户登录

代码如下：

  1  private string GetProcessSerialNumber()
  2         {
  3             try
  4             {
  5                 ManagementObjectCollection ProcessCollection = new ManagementObjectSearcher(
  6                       new System.Management.ManagementScope("\\\\localhost\\root\\cimv2"),
  7                       new System.Management.ObjectQuery("SELECT * FROM Win32_processor")
  8                       ).Get();
  9                 if (ProcessCollection != null && ProcessCollection.Count > 0)
 10                 {
 11                     StringBuilder sb = new StringBuilder();
 12                     foreach (ManagementObject mo in ProcessCollection)
 13                     {
 14                         sb.Append(mo["ProcessorId"]);
 15                     }
 16                     return sb.ToString();
 17                 }
 18                 else
 19                 {
 20                     return "";
 21                 }
 22             }
 23             catch (Exception)
 24             {
