C# Array GetUpperBound

Description

Array GetUpperBound gets the index of the last element of the specified dimension in the array.

Syntax

Array.GetUpperBound has the following syntax.


public int GetUpperBound(
  int dimension
)

Parameters

Array.GetUpperBound has the following parameters.

dimension - A zero-based dimension of the array whose upper bound needs to be determined.

Returns

Array.GetUpperBound method returns The index of the last element of the specified dimension in the array, or -1 if the specified dimension is empty.

Example


/*w  ww .j a  v  a  2s  .  co m*/
using System;

public class Example
{
   public static void Main()  
   {
      int[] integers = { 2, 4, 6, 8, 10, 12, 14, 16, 18, 20 };
      int upper = integers.GetUpperBound(0);
      int lower = integers.GetLowerBound(0);
      Console.WriteLine(lower);
      Console.WriteLine(upper);
      for (int ctr = lower; ctr <= upper; ctr++)
        Console.WriteLine(integers[ctr]);

      int[,] integers2d= { {2, 4}, {3, 9}, {4, 16}, {5, 25}, 
                           {6, 36}, {7, 49}, {8, 64}, {9, 81} }; 
      int rank = integers2d.Rank;  
      Console.WriteLine("Number of dimensions: {0}", rank);      
      for (int ctr = 0; ctr < integers2d.Rank - 1; ctr++)
        Console.WriteLine("   Dimension {0}: from {1} to {2}",
                          ctr, integers2d.GetLowerBound(ctr),
                          integers2d.GetUpperBound(ctr));
      Console.WriteLine("   Values of array elements:");
      for (int outer = integers2d.GetLowerBound(0); outer <= integers2d.GetUpperBound(0);outer++)
        for (int inner = integers2d.GetLowerBound(1); inner <= integers2d.GetUpperBound(1);inner++){
           Console.WriteLine("      {3}{0}, {1}{4} = {2}", outer, inner,integers2d.GetValue(outer, inner), "{", "}");
        }
   }
}

The code above generates the following result.
