It is a rather trivial task to iterate over each item of the generic List using a foreach-loop as follows:

ForEach-loop iteration

Refactorings for converting loops: ForEach to For and back

Let’s take a look at the two CodeRush refactorings allowing us to convert a for-loop into foreach-loop, and a foreach-loop into for-loop, and compare these two loops to see what the difference is between them and which one is preferred.

It uses an iteration variable and is good when iterating over many items sequentially with a precise condition of the iteration termination. No collection of elements is required, but we can use the iteration variable to index a separate collection. In its basic form, the loop contains three sections:
