How do I use foreach with a list in C#?

How do I use foreach with a list in C#?

You can use the foreach loop to iterate through each element in a list. Here's a simple example:

List<string> fruits = new List<string> { "Apple", "Banana", "Cherry" };

foreach (string fruit in fruits) {
    Console.WriteLine(fruit);
}

What if I want to modify the elements while iterating?

You cannot modify the list directly while using foreach. Instead, you can use a regular for loop or create a new list to store modified elements.

Can you show me an example of modifying elements?

Sure! Here's how you can use a for loop to modify elements:

for (int i = 0; i < fruits.Count; i++) {
    fruits[i] = fruits[i].ToUpper();
}

Thanks! Is there a way to use LINQ with lists?

Yes! You can use LINQ to query and manipulate lists. For example:

var upperFruits = fruits.Select(f => f.ToUpper()).ToList();
