Not a good idea. .NET resources are different.

This function needs data returned by a couple of other functions in order to work. It'll update the resources in an .EXE file (with some restrictions), but it will NOT update the resources in the .EXE file that is currently running.

So, if you were looking to save data in your .EXE's own resources, you can't do it.

See the example of using it here[^].

Please have a look on this [link].

Signature of UpdateResource.

C#

 [DllImport("kernel32.dll", SetLastError = true)]
        static extern bool UpdateResource(IntPtr hUpdate, string lpType, string lpName, ushort wLanguage,
            IntPtr lpData, uint cbData);

You might access this API like,

            IntPtr handleExe = BeginUpdateResource(exeFilePath, false);
            
            CultureInfo currentCulture = CultureInfo.CurrentCulture;
            int pid = ((ushort)currentCulture.LCID) & 0x3ff;
            int sid = ((ushort)currentCulture.LCID) >> 10;
            ushort languageID = (ushort)((((ushort)pid) << 10) | ((ushort)sid));

            GCHandle iconHandle = GCHandle.Alloc(resourceData, GCHandleType.Pinned);

Then you might call UpdateResource by sending those parameters.

If you want to know the explanation of each parameter you might see this [link].
