Builds and display single and multidimensional arrays.

The following code example uses GetLowerBound and GetUpperBound to initialize two arrays, one-dimensional and multidimensional.

C# .NET

public static String DoTest()

         for ( int i = my1DIntArray.GetLowerBound(0); i <= my1DIntArray.GetUpperBound(0); i++ )
                  my1DIntArray.SetValue( i+1, i );

         // Displays the bounds and values of the one-dimensional Array.
         strRet += "One-dimensional Array:\r\n";
         strRet += "Rank\tLower\tUpper\r\n";
         strRet += ("0" + "\t" + my1DIntArray.GetLowerBound(0).ToString() + "\t" + my1DIntArray.GetUpperBound(0).ToString() );
         strRet += "\r\nValues:\r\n";
