What does newing an empty struct do in C#?

Question

If you have declared a struct:

struct EmptyResult
{
}

What is the result of creating a variable of type EmptyResult in an instance?

public Foo()
{
    EmptyResult result;
}

Would you expect an allocation on the stack, or is it effectively a no-op?

Answer 1

A C# struct with no fields still has a size of 1. The reason this is so is that the compiler must be able to take the address of a struct using the & operator in unsafe code.

I would expect your struct type to be treated exactly the same way as the byte type.
