C# For Loop

This lesson is part of C# · All levels

Summary

The iteration for combines the initialization, condition, and value addition in one line so that it is suitable for iterations with a fixed number. For can also be used to process two-dimensional data like tables or matrices. In addition, there is foreach to search the contents of the data set without manually managing the index.

Key points

Structure for: initial, condition, then increment, written in a single pair of curves.
The for control variable is made inside the curve so that its coverage is only on the loop.
For a nest is used for two-dimensional structures such as rows and columns.
Loop can start from another value, like 10 to 1 for counting backwards.
To search the collection regardless of index, foreach is much more concise.
