C++ union in C#

Question

I'm translating a library written in C++ to C#, and the keyword 'union' exists once. In a struct. What's the correct way of translating it into C#? And what does it do? It looks something like this; struct Foo { float bar; union { int killroy; float fubar; } as; } JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

Answer 1

You can use explicit field layouts for that: [StructLayout(LayoutKind.Explicit)] public struct SampleUnion { [FieldOffset(0)] public float bar; [FieldOffset(4)] public int killroy; [FieldOffset(4)] public float fubar; } Untested. The idea is that two variables have the same position in your struct. You can of course only use one of them. More informations about unions in struct tutorial
