What is the difference between a While loop and a Foreach loop?

I know these to loops are very similar but can anyone give me specifics on what is the difference between a While loop and a Foreach loop? What would be a specific situation that I would want to use a while loop instead of a foreach and vice versa? Thanks!

A while loop executes orders until a certain condition is met(condition has to be non-zero/null valued for it to execute). A regular for loop provides a variable and a way to count many times it has executed orders and still executes orders while a condition is true. Foreach however takes an array of objects as input and lets you execute commands while it goes through the array giving you access to each object in turn.
