C# - Iterating through collections

C#: Iterating through collections

In C#, collections are used to store a group of related objects. Some examples of collections are arrays, lists, dictionaries, and sets. To access and process the items in a collection, you can use the foreach loop in C#.

The foreach Loop

The foreach loop is used to iterate through each item in a collection. Here's an example using an array:

csharp
int[] numbers = { 1, 2, 3, 4, 5 };
foreach (int number in numbers)
{
    Console.WriteLine(number);
}

In the code above, we declared an array of integers called numbers and used the foreach loop to iterate through each item in the array. The foreach loop consists of two parts: the type of the item (int number) and the collection to iterate through (numbers).

The foreach loop is a convenient way to iterate through collections because it automatically keeps track of the current item and moves to the next item in the collection until there are no more items.

In conclusion, the foreach loop in C# is a powerful tool for iterating through collections. By using the foreach loop, you can process each item in a collection and perform operations on them efficiently and easily.
