Title Body

How can I achieve inheritance (or similar) with structs in C#? I know that an abstract struct isn't possible, but I need to achieve something similar. I need it as a struct because it has to be a value type. And I need inheritance because I need a generic array and methods that I can garantee are there. I think an example will go a long way, so heres some code that won't compile, but shows what I want to achieve; abstract struct Vertex { abstract int SizeInBytes; abstract void SetPointers(); } struct ColorVertex : Vertex { Vector3 Position; Vector4 Color; override int SizeInBytes //static { get { return (3 + 4) * 4; } } override void SetVertexPointers() //static { ... } } class main { static void main() { Vertex[] verts = new Vertex[3]; for(int i = 0; i < 3; i++) verts[i] = new ColorVertex(); verts[0].SetVertexPointers(); //should call ColorVertex.SetVertexPointers externalAPIcall(verts); } } EDIT: The reason I need value types is so that I can make an array of them, and pass it to OpenGL as a vertex buffer. For this, the data needs to be directly contained in this array. I'd be surprised if this were simply not possible to achieve.
