Array: GetLowerBound, GetUpperBound

using System;
public class ArrayTest {
    public static void Main( ) {
       int[] array_1 = new int[5];
      
       for( int i = array_1.GetLowerBound(0); i <= array_1.GetUpperBound(0); i++)
          array_1[i] = i+1;
       for( int j = array_1.GetLowerBound(0); j <= array_1.GetUpperBound(0); j++)
          Console.WriteLine("array_1[{0}] = {1}", j, array_1[j]);
    }
}

array_1[0] = 1
array_1[1] = 2
array_1[2] = 3
array_1[3] = 4
array_1[4] = 5

Get lowerbound and upperbound

using System;
public class MainClass
{
    static void Main() {
        int[,] twoDim = { {1, 2, 3},
                          {4, 5, 6},
                          {7, 8, 9} };
        for( int i = twoDim.GetLowerBound(0);
             i <= twoDim.GetUpperBound(0);
             ++i ) {
            for( int j = twoDim.GetLowerBound(1);
                 j <= twoDim.GetUpperBound(1);
                 ++j ) {
                Console.WriteLine( twoDim[i,j] );
            }
        }
    }
}
