How to Iterate Over a List with Index in C# ?

Answer

To iterate over a list in C# using List, you can use foreach loops or for loops with indexing.

✐ Examples

1 Iterate Over List with foreach Loop

In this example,

We create a List named numbers with integer elements.
We use a foreach loop to iterate over the list directly.
Within the loop, we perform operations on each element or print it.

C# Program

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        List<int> numbers = new List<int> { 10, 20, 30, 40, 50 };
        foreach (int number in numbers)
        {
            Console.WriteLine(number);
        }
    }
}

Output

2 Iterate Over List with for Loop and Indexing

In this example,

We create a List named names with string elements.
We use a for loop with indexing to iterate over the list.
Within the loop, we access elements using their indices and perform operations or print them.

C# Program

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        List<string> names = new List<string> { "Alice", "Bob", "Charlie", "David" };
        for (int i = 0; i < names.Count; i++)
        {
            Console.WriteLine(names[i]);
        }
    }
}

Output

Alice
Bob
Charlie
David
