问题:
If I have a Vista .ico file which contains a 16x16, 32x32, 256x256 etc. version of an icon, I can successfully load it as a .NET Icon by simply doing -:
Icon myIcon = new Icon("C:\\MyIcon.ico");
I can then access all of the various sized images in the icon. I can even access the 256x256 Vista PNG using methods detailed HERE.
However, I haven't found a way to get the full set of icon images from a Vista executable. Unfortunately, doing this -:
Icon myIcon = Icon.ExtractAssociatedIcon("C:\\MyExe.exe");
...only results in a single 32x32 image being extracted. Is there a way get the entire set of images from an executable as a .NET Icon? Preferably one that also works in XP.
回答1:
Have a look at this article 'IconLib' on CodeProject. Also, look at this version using the 'ExtractIconExA' API via pinvoke in VB.NET.
Hope this helps.

try this snippet with PrivateExtractIcons API:
[DllImport("User32.dll", CharSet = CharSet.Auto)] internal static extern UInt32 PrivateExtractIcons(String lpszFile, int nIconIndex, int cxIcon, int cyIcon, IntPtr[] phicon, IntPtr[] piconid, UInt32 nIcons, UInt32 flags); IntPtr[] phicon = new IntPtr[] { IntPtr.Zero }; IntPtr[] piconid = new IntPtr[] { IntPtr.Zero }; PrivateExtractIcons(path, 0, cx, cy, phicon, piconid, 1, 0); if (phicon[0] != IntPtr.Zero) return System.Drawing.Icon.FromHandle(phicon[0]);
