This sample shows how to get data from XLS spreadsheet and export them to two-dimensional (2D) arrays in C# and Visual Basic .NET using Bytescout Spreadsheet SDK.

C#

using System;

namespace Bytescout.Spreadsheet.Demo.Csharp.ExportTo2DArray
{
    class Program
    {
        static void Main(string[] args)
        {
            const string inputFile = @"StockPricesSpreadsheet.xls";

            // Open and load spreadsheet
            Spreadsheet spreadsheet = new Spreadsheet();
            spreadsheet.LoadFromFile(inputFile);

            // Get the data from the spreadsheet
            string[,] stockPrices = spreadsheet.ExportTo2DArray();

            // Close spreadsheet
            spreadsheet.Close();

            // Display data in data table
            for(int i = 0; i < stockPrices.GetLength(0); i++)
            {
                for(int j = 0; j < stockPrices.GetLength(1); j++)
                {
                    Console.Write(stockPrices&#91;i,j&#93; + " ");
                }
                Console.WriteLine();
            }

            // Pause
            Console.ReadLine();
        }
    }
}
