C# C# Objects Loops and Final Touches Foreach Loops

What is the basic format of a foreach loop?

I see where the presenter coded foreach(Invader invader in invaders)

But, where is this

Invader invader in invaders

coming from?

From the MS documentation here, I see that you can break down this format to:

foreach("local variable type identifier" in "expression") { }

So here, "invader" would be the local variable, "Invader" would be the local variable type identifier" and "invaders" would be the expression. This foreach loop would loop through every "invader" in the collection.

Correct?

Yes, because "Invader" is the type whereas "invader" is the variable. Both of these things together create "the local variable type identifier" mentioned in ms docs. Thus, the "invaders" collection would be iterated through, the iterator being the "invader".

TLDR; You are correct and answered your own question.
