How to find the length of an Array in C#

// C# program to find the
// the total number of
// elements in 1-D Array
using System;
namespace geeksforgeeks {

class GFG {

    // Main Method
    public static void Main()
    {

        // declares a 1D Array of string.
        string[] weekDays;

        // allocating memory for days.
        weekDays = new string[] {"Sun", "Mon", "Tue", "Wed",
                                       "Thu", "Fri", "Sat"};

        // Displaying Elements of the array
        foreach(string day in weekDays)
            Console.Write(day + " ");

        Console.Write("\nTotal Number of Elements: ");

        // using Length property
        Console.Write(weekDays.Length);
    }
}
}
