How to access members of an struct like an array in C#?

Question

Lets say I have a struct with more than hundred elements with complex names. And I am passing a struct of the struct type described to a function using ref, like this:

Answer 1

While you can use the struct LayoutKind attribute to force simple types to share memory like a "C" Union, you still cannot make an array share memory with simple types because ref types (aka garbage collected types) don't work with the attribute. The concept of C shortcuts like memset of a struct don't map to C# in any way, because C# is a safe language. In fact, that is a Good Thing. Many bugs have come from these kinds of memory addressing shortcuts.

If you want to simulate this behavior, create a class with properties that map to specific members of a backing array, but again, why do this? There are much better data structures to suit your needs in C# such as List, SortedList, Dictionary, Map, Stack, etc. that are safe.
