C# Signature:

[DllImport("kernel32.dll", SetLastError=true)]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool GetVolumePathNamesForVolumeNameW(string lpszVolumeName,
        char [] lpszVolumePathNames, uint cchBuferLength,
        ref UInt32 lpcchReturnLength);

VB Signature:

Declare Function GetVolumePathNamesForVolumeName Lib "kernel32.dll" (TODO) As TODO

User-Defined Types:

None.

Alternative Managed API:

Do you know one? Please contribute it!

Notes:

Using StringBuilder for the buffer does not work since this function returns the names as a bunch of strings separated by the null character ('\0'). So StringBuilder would only report the first item. Therefore we store it in a char array, which can later be converted to a bunch of strings.

Tips & Tricks:

Please add some!

Sample Code:

        UInt32 dwRequired = 0;

        char[] buffer = new char[260];

        if (!GetVolumePathNamesForVolumeName(volumeName, buffer, (uint)buffer.Length, ref dwRequired))
        {
        // Not enough room in buffer perhaps? Try a bigger one
        buffer = new char[dwRequired];
        if (!GetVolumePathNamesForVolumeName(volumeName, buffer, (uint)buffer.Length, ref dwRequired))
            throw new Win32Exception();
        }
