How to Initialize a List in C# ?

Answer

To initialize a list in C#, you can use the List class from the System.Collections.Generic namespace. You can create an empty list or initialize it with elements.

✐ Examples

1 Initialize an Empty List

In this example,

We use the List constructor to create an empty list of strings and assign it to the variable emptyList.
We print the count of elements in the list to standard output to verify it's empty.

C# Program

using System;
using System.Collections.Generic;

class Program {
    static void Main() {
        List<string> emptyList = new List<string>();
        Console.WriteLine("Empty List initialized. Count: " + emptyList.Count);
    }
}

Output

Empty List initialized. Count: 0

2 Initialize a List with Elements

In this example,

We use the List constructor and provide initial values to create a list of strings.
The list is assigned to the variable fruits.
We print the list's elements to standard output to verify its contents.

C# Program

using System;
using System.Collections.Generic;

class Program {
    static void Main() {
        List<string> fruits = new List<string> {"Apple", "Banana", "Cherry"};
        Console.WriteLine("List with Elements:");
        foreach (string fruit in fruits) {
            Console.WriteLine(fruit);
        }
    }
}

Output

List with Elements:
Apple
Banana
Cherry
