Major difference between Foreach and Using

Question

This could even be a simple question even a school boy can answer.

What is the similarities and differences between "ForEach" and "Using" (asked in an interview).

My assumption was

1)Both are enumerable

2) Using can handle memory resources,but foreach can't.using supports IDisposable,foreach can't.

I wish to know the answers.

Answer 1

1. Nope
2. Nope, foreach will dispose of your IEnumerable if it implements IDisposable.
