What does Array.Length property of array class do in C#?

The Array.Lenth property in C# is used to find the length of the array.

Let’s set the array class first −

Array arr = Array.CreateInstance(typeof(String), 3);
arr.SetValue("Electronics", 0);
arr.SetValue("Clothing", 1);
arr.SetValue("Appliances", 2);

Now since the array’s length is 3, the Length property will give the result 3 −

arr.Length

The following is the code to implement Array.Length property of array class −

Example

 Live Demo

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace lower {
   class Program {
      static void Main(string[] args) {
         Array arr = Array.CreateInstance(typeof(String), 3);
         arr.SetValue("Electronics", 0);
         arr.SetValue("Clothing", 1);
         arr.SetValue("Appliances", 2);

         Console.WriteLine("Length: {0}",arr.Length.ToString());

         Console.ReadLine();
      }
   }
}

Output

Length: 3
