Question

How to use GetUpperBound() and GetLowerBound() methods to get the upper and lower bound of an array in C#

Answer 1

using System;

namespace ConsoleApplication_C_Sharp
{
    class Program
    {
        static void Main(string[] args)
        {
            int[] arr = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };

            int upper = arr.GetUpperBound(0);
            int lower = arr.GetLowerBound(0);
            Console.WriteLine("index from: {0} to: {1}", lower, upper);
        }
    }
}


/*
run:
   
index from: 0 to: 9

using System;

namespace ConsoleApplication_C_Sharp
{
    class Program
    {
        static void Main(string[] args)
        {
            int[,] arr2D = { { 1, 2 }, { 3, 4 }, { 5, 6 }, { 7, 8 }, 
                             { 9, 10 }, { 11, 12 }, { 13, 14 } };

            for (int i = 0; i < arr2D.Rank; i++)
                Console.WriteLine("Dimension {0}: index from {1} to {2}",
                                  i, arr2D.GetLowerBound(i),
                                  arr2D.GetUpperBound(i));
        }
    }
}


/*
run:
   
Dimension 0: index from 0 to 6
Dimension 1: index from 0 to 1
  
*/
