Icon.FromHandle: should I Dispose it, or call DestroyIcon?

Question

I use Win32 SHGetFileInfo to get a handle to the icon belonging to a certain file. There are a lot of descriptions how to do this, also on stackoverflow, for instance: Get i

Answer 1

I have had NO END of grief in this area - I've been trying to animate a form's icon (and consequently the one in the task bar) without it leaking resources.

When I disposed of the icon (as suggested on MSDN) resources leaked, when I used "DestroyIcon" all subsequent updates failed. This code below shows everything in the correct order.

API Declaration:

[System.Runtime.InteropServices.DllImport("user32.dll", CharSet = CharSet.Auto)]
extern static bool DestroyIcon(IntPtr handle);

FINALLY the solution:

IntPtr iconHandle = dynamicBitmap.GetHicon();
Icon tempManagedRes = Icon.FromHandle(iconHandle);
this.Icon = (Icon)tempManagedRes.Clone();
tempManagedRes.Dispose();
DestroyIcon(iconHandle);
