Which of the following is the correct way to obtain the number of elements present in the array given below?

    int[] intMyArr = {25, 30, 45, 15, 60};

1. intMyArr.GetMax;
2. intMyArr.Highest(0);
3. intMyArr.GetUpperBound(0);
4. intMyArr.Length;
5. intMyArr.GetMaxElements(0);

using System;
    
public class Test
{ 
   public static void Main()
   { 
        int[] intMyArr = { 25, 30, 45, 15, 60, 78, 99 };
        Console.WriteLine(intMyArr.Length);
        Console.WriteLine(intMyArr.GetUpperBound(0)+1);
   } 
}
/* 
Output :
