获取硬盘序列号

Question

我想获得硬盘序列号.我怎么能这样做？我尝试了两个代码,但我没有得到

StringCollection propNames = new StringCollection();
ManagementClass driveClass = new ManagementClass("Win32_DiskDrive");
PropertyDataCollection  props = driveClass.Properties;
foreach (PropertyData driveProperty in props) 
{
    propNames.Add(driveProperty.Name);
}
int idx = 0;
ManagementObjectCollection drives = driveClass.GetInstances();
foreach (ManagementObject drv in drives)
       {
          Label2.Text+=(idx + 1);
          foreach (string strProp in propNames)
           {
            //Label2.Text+=drv[strProp];
         Response.Write(strProp + "   =   " + drv[strProp] + "</br>");
          }
    }

在这一个我没有得到任何唯一序列号.
第二个是

string drive = "C";
ManagementObject disk = new ManagementObject("win32_logicaldisk.deviceid=\"" + drive + ":\"");
disk.Get();
Label3.Text = "VolumeSerialNumber="+ disk["VolumeSerialNumber"].ToString();

我来了VolumeSerialNumber.但它并不是独一无二的.如果我格式化硬盘,这将改变.我怎么能得到这个？

嗯,看着你的第一组代码,我想你已经检索过(可能是？)硬盘模型.序列#来自Win32_PhysicalMedia.

获取硬盘型号

    ManagementObjectSearcher searcher = new
    ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");

   foreach(ManagementObject wmi_HD in searcher.Get())
   {
    HardDrive hd = new HardDrive();
    hd.Model = wmi_HD["Model"].ToString();
    hd.Type  = wmi_HD["InterfaceType"].ToString(); 
    hdCollection.Add(hd);
   }

获取序列号

 searcher = new
    ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");

   int i = 0;
   foreach(ManagementObject wmi_HD in searcher.Get())
   {
    // get the hard drive from collection
    // using index
    HardDrive hd = (HardDrive)hdCollection[i];

    // get the hardware serial no.
    if (wmi_HD["SerialNumber"] == null)
     hd.SerialNo = "None";
    else
     hd.SerialNo = wmi_HD["SerialNumber"].ToString();

    ++i;
   }

希望这可以帮助 :)

我在项目中使用了以下方法,并且它已成功运行.

private string identifier(string wmiClass, string wmiProperty)
//Return a hardware identifier
{
    string result = "";
    System.Management.ManagementClass mc = new System.Management.ManagementClass(wmiClass);
    System.Management.ManagementObjectCollection moc = mc.GetInstances();
    foreach (System.Management.ManagementObject mo in moc)
    {
        //Only get the first one
        if (result == "")
        {
            try
            {
                result = mo[wmiProperty].ToString();
                break;
            }
            catch
            {
            }
        }
    }
    return result;
}

你可以调用上面提到的方法,

string modelNo = identifier("Win32_DiskDrive", "Model");
string manufatureID = identifier("Win32_DiskDrive", "Manufacturer");
string signature = identifier("Win32_DiskDrive", "Signature");
string totalHeads = identifier("Win32_DiskDrive", "TotalHeads");

如果您需要唯一标识符,请使用这些ID的组合.

@ Sprunth的答案有一个简单的方法.

private void GetAllDiskDrives()
    {
        var searcher = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");

        foreach (ManagementObject wmi_HD in searcher.Get())
        {
            HardDrive hd = new HardDrive();
            hd.Model = wmi_HD["Model"].ToString();
            hd.InterfaceType = wmi_HD["InterfaceType"].ToString();
            hd.Caption = wmi_HD["Caption"].ToString();

            hd.SerialNo =wmi_HD.GetPropertyValue("SerialNumber").ToString();//get the serailNumber of diskdrive

            hdCollection.Add(hd);
        }

 }


public class HardDrive
{
    public string Model { get; set; }
    public string InterfaceType { get; set; }
    public string Caption { get; set; }
    public string SerialNo { get; set; }
}
