Comments on: Uncommon C# : Using C style unions in C# http://www.dijksterhuis.org/uncommon-style-unions/ Information, news about programming in C# Sun, 21 Feb 2010 16:48:33 -0600 http://wordpress.org/?v=2.8.4 hourly 1 By: Gareth http://www.dijksterhuis.org/uncommon-style-unions/comment-page-1/#comment-340 Gareth Mon, 23 Feb 2009 11:57:07 +0000 http://www.dijksterhuis.org/?p=672#comment-340 Was using LayoutKind.Explicit the other day, whilst coding up a struct which held a PCX Image Header. Was thinking I could load the header into a byte array sitting at FieldOffset 0, and then have relevant fields such as XMax, YMax etc. populated according to their corresponding field offsets. Alas, you can't use reference types like a byte array with LayoutKind.Explicit! (It'll compile it for you, though). Makes sense when you think about it, but was annoying all the same.
