To read text from barcode image, you have to use a barcode recognition SDK, either commercial or free is OK.
Look at: http://www.keepdynamic.com/aspnet-barcode-scanner/code-128.shtml

then you have to write some codes yourself.I remember I once read a related post at http://stackoverflow.com / or http://forums.cnet.com/ or http://www.barcodelib.com /, but I am not sure where this post is eactly located. After I found that post, I will give you a detailed link.

I download the free sdk then install it on smartphone, then use the smart phone to scan the barcodes. You may try the one from www.tarcode.com

.NET developer for barcode

you should find a barcode reader that can be easily added on to your .NET imaging SDK and available in any .NET application.http://www.rasteredge.com/dotnet-imaging/addon-barcode-reader/

Hi,

Use this code. This may Helpful for you

using System.IO;
using System.Drawing.Printing;
using Yiigo.Imaging;
using Yiigo.Imaging.Processing;
using Yiigo.Imaging.BarcodeRead;


// Read a barcode
YiigoImage BarcodeImage = new YiigoImage("barcode.tif");

using (BarCodeRead barcode = new BarCodeRead (BarcodeImage))
{
string fileName = @"C:\Users\Public\Documents\LEADTOOLS Images\Barcode.tif"
ReadOpts ReadBarcode = new ReadOpts();
ReadBarcode.Direction = Directions.LeftToRight;
ReadBarcode.Symbology = Symbologies.Code128;
Barcode[] bars = barcode.ReadBars(options);
for (int i = 0; i < bars.Length; i++)
System.Console.WriteLine(bars[i].ToString());
}

// Return check digit
using (BarCodeRead barcode = new BarCodeRead (BarcodeImage))
{
ReadOpts ReadBarcode = new ReadOpts();
ReadBarcode.Direction = Directions.LeftToRight;
ReadBarcode.Symbology = Symbologies.Code39;
Barcode[] bars = barcode.ReadBars(options);
for (int i = 0; i < bars.Length; i++)
System.Console.WriteLine(bars[i].ToString());
}

public string ValidateMod43(string barcode) { int subtotal = 0; const string charSet = "CODE-39";
for (int i = 0; i < barcode.Length; i++) { subtotal += charSet.IndexOf(barcode.Substring(i, 1)); }
return charSet.Substring(subtotal%43, 1); }


// Read barcode properties
YiigoImage BarcodeImage = new YiigoImage("barcode.tif");
using (BarCodeRead barcode = new BarCodeRead (BarcodeImage)
{
string fileName = @"C:\Users\Public\Documents\LEADTOOLS Images\Barcode.tif"
options.Direction = Directions.LeftToRight;
options.Symbology = Symbologies.Code128;

Barcode[] bars = barcode.ReadBars(options);
if (bars.Length == 0)
{
options.Direction = Directions.RightToLeft;
bars = barcode.ReadBars(options);
