检索设备的serialno

Question

我无法从serialno中选择Win32_DiskDrive。当我正在调试它时，它显示我“未找到”

代码如下：

string serialno="";
ManagementObjectSearcher mosDisks = new ManagementObjectSearcher("SELECT * FROM     Win32_DiskDrive");

foreach (ManagementObject moDisk in mosDisks.Get())
{
  serialno = moDisk["SerialNumber"].ToString();

  dataGridView1.Columns[4].HeaderText = "SerialNo";
  dataGridView1.Columns[4].DataPropertyName = serialno;
  row.Cells[4].Value = dataGridView1.Columns[4].DataPropertyName;
}

Answer 1

您可以尝试使用此代码 - 基于Win32_PhysicalMedia

  var searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");
   foreach(ManagementObject wmi_HD in searcher.Get())
   {
       var serialno = wmi_HD["SerialNumber"].ToString();
   }
