Diskpart UniqueID - C#如何获得id

Question

我熟悉VolumeSerialNumber，我需要磁盘ID，如磁盘部分所示：

WD我的护照0740 USB设备磁盘ID: 08B29B51类型: USB状态:联机路径:0目标:0 LUN ID :0位置路径:不可用当前只读状态:无只读:无启动磁盘:无休眠文件磁盘:无Crashdump磁盘:无群集磁盘:无群集磁盘

我在网上(WMI)或论坛上找不到任何支持这个请求的东西。有人有主意吗？

--这是我为从Driveletter获取DiskID而创建的方法。可能是更好的方法，但目前这对我来说是有效的。谢谢你的帮助。

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(); }

查看DiskDrive WMI类。它有一个名为Signature的字段，它包含这个ID。但是请注意，这不是一个字符串，而是一个数字。如果您想要匹配您在DiskPart中看到的内容，则必须将该数字显示为十六进制字符串(signature.ToString("X"))

下面是打印驱动器签名的代码：

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"));
    }
}
