How to Get Length of a List in C# - Step by Step Examples

How to Get Length of a List in C# ?

Answer

To get the length of a list in C#, you can use the Count property of the List class.


✐ Examples

1 Get Length of an Integer List

In this example,

  1. We create a list named numbers with integer values.
  2. We use the Count property of the list object numbers to get the number of elements in the list.
  3. The Count property returns the number of elements in the list.
  4. Finally, we print the count to the console using Console.WriteLine().

C# Program

using System;
using System.Collections.Generic;

class Program {
    static void Main() {
        List<int> numbers = new List<int> { 1, 2, 3, 4, 5 };
        Console.WriteLine("Length of the list is: " + numbers.Count);
    }
}

Output

Length of the list is: 5

2 Get Length of a String List

In this example,

  1. We create a list named fruits with string values.
  2. We use the Count property of the list object fruits to get the number of elements in the list.
  3. The Count property returns the number of elements in the list.
  4. Finally, we print the count to the console using Console.WriteLine().

C# Program

using System;
using System.Collections.Generic;

class Program {
    static void Main() {
        List<string> fruits = new List<string> { "apple", "banana", "cherry" };
        Console.WriteLine("Length of the list is: " + fruits.Count);
    }
}

Output

Length of the list is: 3
