提取分配给文件的正确16x16图标？

Question

I tied SHGetFileInfo and ExtractIconEx, both return a normal 32x32 icon and 16x16 with only 16 colors, and it looks awful. How do I extract a full color icon?

My code

SHFILEINFO shinfo = new SHFILEINFO();
IntPtr hImgSmall = SHGetFileInfo(fileName, 0, ref shinfo, (uint)Marshal.SizeOf(shinfo), SHGFI_ICON | SHGFI_SMALLICON);
Icon icon = (Icon)System.Drawing.Icon.FromHandle(shinfo.hIcon).Clone();
DestroyIcon(shinfo.hIcon);

Answer 1

I tried this example link text and works.....got 16*16 with alpha channel. Try it.

Answer 2

Did you tried the following?

Icon LargeIcon = Icon.ExtractAssociatedIcon(fileName);
Icon SmallIcon = new Icon(LargeIcon, 16, 16);
