You can find the code at
https://github.com/Wagnerp/Windows-API-CodePack-NET/blob/main/Source/Origina...

Inside source/WindowsAPICodePack/Core/Interop/TaskDialogs/NativeTaskDialog.cs:
> private static IntPtr AllocateAndMarshalButtons(TaskDialogNativeMethods.TaskDialogButton[] structs)
> {
>     IntPtr initialPtr = Marshal.AllocHGlobal(
>         Marshal.SizeOf(typeof(TaskDialogNativeMethods.TaskDialogButton)) * structs.Length);
> IntPtr currentPtr = initialPtr;
> foreach (TaskDialogNativeMethods.TaskDialogButton button in structs)
> {
>     Marshal.StructureToPtr(button, currentPtr, false);
>     currentPtr = (IntPtr)((int)currentPtr + Marshal.SizeOf(button));
> }
>
> return initialPtr;
>
