C# Loops

It's often necessary to perform a sequence of logic multiple times in a program. For example, there might be a list of some items where each item needs the same processing. This processing is performed with language constructs called loops. In C# there are four types of loops—the while loop, the do loop, the for loop, and the foreach loop. Each has its own benefits for certain tasks.
