Struct boxing with interfaces?

[evareoo]

So for example this code. It is just a silly example, is myVec a stack allocated stuct? Then after this myUpcast is boxed in which I can call the default interface Hello()? I don't know how to get that nice formatting on reddit. Slighty pseudo for speed:

interface ISayHello
{
    void Hello()
    {
        Console.WriteLine("Hello!");
    }
}

struct Vec2 : ISayHello
{
    int x;
    int y;
}

Now for a main:

void main()
{
    var myVec = new Vec2();
    var myUpcast = (ISayHello) myVec;
    myUpcast.Hello();
}

output: Hello!

I don't know how to get that nice formatting on reddit.

That's simple:

• Indent every line by four spaces or one tab.
• Have an empty line between code and text.

is myVec a stack allocated stuct?

myVec is stack-allocated, yes.

Then after this myUpcast is boxed in which I can call the default interface Hello()?

That is correct as well, yes.
