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：

  private string GetProcessSerialNumber()
         {
             try
             {
                 ManagementObjectCollection ProcessCollection = new ManagementObjectSearcher(
                       new System.Management.ManagementScope("\\\\localhost\\root\\cimv2"),
                       new System.Management.ObjectQuery("SELECT * FROM Win32_processor")
                       ).Get();
                 if (ProcessCollection != null && ProcessCollection.Count > )
                 {
                     StringBuilder sb = new StringBuilder();
                     foreach (ManagementObject mo in ProcessCollection)
                     {
                         sb.Append(mo["ProcessorId"]);
                     }
                     return sb.ToString();
                 }
                 else
                 {
                     return "";
                 }
             }
             catch (Exception)
             {
                 return "";
             }
         }         private string GetMotherBoardSerialNumber()
         {
             try
             {
