You can get the localized display name with the SHGetFileInfo
API:
public static string GetDisplayName(Environment.SpecialFolder specialFolder)
{
IntPtr pidl = IntPtr.Zero;
try
{
HResult hr = SHGetFolderLocation(IntPtr.Zero, (int) specialFolder, IntPtr.Zero, 0, out pidl);
if (hr.IsFailure)
return null;
SHFILEINFO shfi;
if (0 != SHGetFileInfo(
pidl,
FILE_ATTRIBUTE_NORMAL,
out shfi,
(uint)Marshal.SizeOf(typeof(SHFILEINFO)),
SHGFI_PIDL | SHGFI_DISPLAYNAME))
{
return shfi.szDisplayName;
}
return null;
}
finally
{
if (pidl != IntPtr.Zero)
ILFree(pidl);
}
}
public static string GetDisplayName(string path)
{
SHFILEINFO shfi;
if (0 != SHGetFileInfo(
path,
FILE_ATTRIBUTE_NORMAL,
out shfi,
(uint)Marshal.SizeOf(typeof(SHFILEINFO)),
SHGFI_DISPLAYNAME))
{
return shfi.szDisplayName;
}
return null;
}
