C# 如何发现usb大容量存储设备（外部硬盘驱动器）？

我已经尝试了这两种不同的功能，但没有达到预期效果。

DriveType枚举还有一个可移动属性：

System.IO.DriveType driveType = drive.DriveType;
switch (driveType)
{
    case System.IO.DriveType.CDRom:
        break;
    case System.IO.DriveType.Fixed:
        // Local Drive
        break;
    case System.IO.DriveType.Network:
        // Mapped Drive
        break;
    case System.IO.DriveType.NoRootDirectory:
        break;
    case System.IO.DriveType.Ram:
        break;
    case System.IO.DriveType.Removable:
        // Usually a USB Drive
        break;
    case System.IO.DriveType.Unknown:
        break;
}

您可以查询类型。

根据您的估计，什么决定了任何特定的基于USB闪存的大容量存储是“硬盘驱动器”还是“拇指驱动器”？对于操作系统来说，区别在于分区。

System.IO.DriveType driveType = drive.DriveType;
switch (driveType)
{
    case System.IO.DriveType.CDRom:
        break;
    case System.IO.DriveType.Fixed:
        // Local Drive
        break;
    case System.IO.DriveType.Network:
        // Mapped Drive
        break;
    case System.IO.DriveType.NoRootDirectory:
        break;
    case System.IO.DriveType.Ram:
        break;
    case System.IO.DriveType.Removable:
        // Usually a USB Drive
        break;
    case System.IO.DriveType.Unknown:
        break;
}
