How to Append an Element to a List in C# ?

Answer

To append an element to a list in C#, you can use the Add method of the List class.

✐ Examples

1 Append an Element to a List

In this example,

We create a List named numbers with initial integer values.
We use the Add method of the List numbers to append a new integer to the list.
The Add method modifies the original list by adding the new element at the end.
Finally, we print the updated list to the console.

C# Program

using System;
using System.Collections.Generic;

class Program {
    static void Main() {
        List<int> numbers = new List<int> { 1, 2, 3, 4 };
        numbers.Add(5);
        Console.WriteLine("Updated list: " + string.Join(", ", numbers));
    }
}

Output

Updated list: 1, 2, 3, 4, 5

2 Append Multiple Elements to a List

In this example,

We create a List named numbers with initial integer values.
We define another list named newElements containing elements to be appended.
We use the AddRange method to add all elements from newElements to numbers at once.
Finally, we print the updated list to the console.

C# Program

using System;
using System.Collections.Generic;

class Program {
    static void Main() {
        List<int> numbers = new List<int> { 1, 2, 3, 4 };
        List<int> newElements = new List<int> { 5, 6, 7 };
        numbers.AddRange(newElements);
        Console.WriteLine("Updated list: " + string.Join(", ", numbers));
    }
}

Output

Updated list: 1, 2, 3, 4, 5, 6, 7
