Diskpart UniqueID-C＃如何获取该ID

Question

I'm familiar with VolumeSerialNumber, i need the Disk ID same as shown in diskpart:

WD My Passport 0740 USB Device Disk ID: 08B29B51 Type : USB Status : Online Path : 0 Target : 0 LUN ID : 0 Location Path : UNAVAILABLE Current Read-only State : No Read-only : No Boot Disk : No Pagefile Disk : No Hibernation File Disk : No Crashdump Disk : No Clustered Disk : No

I can't find anything on the web (WMI) or forums that supports this request. Anybody has an idea?

Check out the Win32_DiskDrive WMI Class. It has a field called Signature which contains this ID. Note, though, that this is not a string , but a number. If you want to match what you see in DiskPart, you'll have to display that number as a hexadecimal string ( signature.ToString("X") )

Here's code to print out drive signatures:

public void PrintDiskDriveSignature()
{
    var searcher = new ManagementObjectSearcher
              (@"\\localhost\ROOT\CIMv2", "select * from Win32_DiskDrive");
    var drives = searcher.Get();
    foreach (var drive in drives)
    {
        string name = drive["Name"].ToString();
        uint signature = (uint) drive["Signature"];
        Console.WriteLine("{0}: {1}", name, signature.ToString("X"));
    }
}

This is the Method i created for getting DiskID from Driveletter. Probably are better ways to do this, but this worked for me for now. Thanks for all your help.

  public static string GetDiskID(char Drive) { uint volumeSerialNumber = 0; bool DriveFound = false; foreach (ManagementObject drive in new ManagementObjectSearcher("select DeviceID, Signature from Win32_DiskDrive").Get()) { foreach (ManagementObject partition in new ManagementObjectSearcher(String.Format("associators of {{Win32_DiskDrive.DeviceID='{0}'}} where AssocClass = Win32_DiskDriveToDiskPartition", drive["DeviceID"])).Get()) { if (partition != null) { ManagementObject logical = new ManagementObjectSearcher(String.Format("associators of {{Win32_DiskPartition.DeviceID='{0}'}} where AssocClass = Win32_LogicalDiskToPartition", partition["DeviceID"])).First(); if (logical != null) { if (logical["Name"] != null) { string logicalName = logical["Name"].ToString(); if (logicalName[0] == Drive) { volumeSerialNumber = (uint)drive["Signature"]; DriveFound = true; break; } } } } } if (DriveFound) break; } var serial = volumeSerialNumber.ToString("x"); while (serial.Length < 8) { serial = serial.Insert(0, "0"); } return serial.ToUpper(); }
