c# - 将路径转换为其 GUID 形式

Question

我需要将路径(例如 C:\)转换为该卷的 GUID 形式(例如 \\\?\Volume{XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}\).

C# 中是否有任何函数可以执行类似的操作？

您需要 P/Invoke GetVolumeNameForVolumeMountPoint:

static string GetVolumeGuidPath(string mountPoint)
{
    StringBuilder sb = new StringBuilder(50);
    GetVolumeNameForVolumeMountPoint(mountPoint, sb, 50);
    return sb.ToString();
}

[DllImport("kernel32.dll", SetLastError = true)]
static extern bool GetVolumeNameForVolumeMountPoint(
    string lpszVolumeMountPoint,
    [Out] StringBuilder lpszVolumeName,
    int cchBufferLength);
