Can you give me examples of foreach loops in C#?

Can you give me examples of foreach loops in C#?

Sure! The foreach loop in C# is used to iterate over a collection, such as an array or a list. Here's a simple example:

string[] fruits = { "Apple", "Banana", "Cherry" };
foreach (string fruit in fruits) {
    Console.WriteLine(fruit);
}

This will print each fruit in the array.

What if I want to use it with a list instead?

Great question! You can use foreach with a list like this:

List<int> numbers = new List<int> { 1, 2, 3, 4, 5 };
foreach (int number in numbers) {
    Console.WriteLine(number);
}
}

This will print each number in the list.

Can I modify the elements while iterating?

No, you cannot modify the collection directly while using foreach. If you need to modify elements, consider using a for loop instead.

Are there any performance considerations with foreach?

Yes, foreach can be less efficient than a for loop in some cases, especially with large collections. It's best to use it for readability unless performance is critical.
