Guide Overview
It's easy to use BC.NetBarcodeReader.All2D library to read and recognize barcode symbologies from images in your .NET projects. Here we will show you in simple steps. Please firstly download and get the free trial library (BC.NetBarcodeReaderTrial.All2D.dll). And the only thing for the integration of our library is to add your project reference to it.
We take the Console Application as an example of how to use BC.NetBarcodeReader.All2D library to scan and read 2d barcodes from images. For ease of use, here are simple code examples for C# and VB.NET developers. To recognize all 2d and 1d barcodes, you should use BC.NetBarcodeReader.All library.
1. You can scan and read a single 2D barcode type from an image using BC.NetBarcodeReader.All2D library.
How to in C#
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using BC.NetBarcodeReaderTrial.All2D;
namespace BC.NetBarcodeReaderDemo
{
class Program
{
static void Main(string[] args)
{
ReadOneBarcodeTypefromImage();
}
public static void ReadOneBarcodeTypefromImage()
{
string[] data = NetBarcodeReader.Recognize("Qrcode.png", NetBarcodeReader.Qrcode);
/*string[] data1 = NetBarcodeReader.Recognize("F:/Pdf417.bmp", NetBarcodeReader.Pdf417);
string[] data2 = NetBarcodeReader.Recognize("F:/Datamatrix.gif", NetBarcodeReader.Datamatrix);*/
foreach (string result in data)
{
Console.WriteLine(result);
}
Console.ReadKey();
}
}
}
How to in VB.NET
Imports System
Imports System.Collections.Generic
Imports System.Linq
Imports System.Text
Imports BC.NetBarcodeReaderTrial.All2D
Module BCNetBarcodeReaderDemo
Sub Main()
ReadOneBarcodeTypefromImage()
End Sub
Public Sub ReadOneBarcodeTypefromImage()
Dim data As String() = NetBarcodeReader.Recognize("Qrcode.png", NetBarcodeReader.Qrcode)
'Dim data1 As String() = NetBarcodeReader.Recognize("F:/Pdf417.tif", NetBarcodeReader.Pdf417)
'Dim data2 As String() = NetBarcodeReader.Recognize("F:/Datamatrix.png", NetBarcodeReader.Datamatrix)
For Each result As String In data
Console.WriteLine(result)
Next
Console.ReadKey()
End Sub
End Module
2. You can scan and read more than one 2D barcode types from image using BC.NetBarcodeReader.All2D library.
How to in C#
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using BC.NetBarcodeReaderTrial.All;
namespace BC.NetBarcodeReaderDemo
{
class Program
{
static void Main(string[] args)
{
ReadMultipleBarcodeTypesfromImage();
}
public static void ReadMultipleBarcodeTypesfromImage()
{
string[] data = NetBarcodeReader.Recognize("Multiple.jpg", NetBarcodeReader.Qrcode);
string[] data1 = NetBarcodeReader.Recognize("Multiple.jpg", NetBarcodeReader.Pdf417);
foreach (string result in data)
{
Console.WriteLine(result);
}
foreach (string result1 in data1)
{
Console.WriteLine(result1);
}
Console.ReadKey();
}
}
}
How to in VB.NET
Imports System
Imports System.Collections.Generic
Imports System.Linq
Imports System.Text
Imports BC.NetBarcodeReaderTrial.All
Module BCNetBarcodeReaderDemo
Sub Main()
ReadMultipleBarcodeTypesfromImage()
End Sub
Public Sub ReadMultipleBarcodeTypesfromImage()
Dim data As String() = NetBarcodeReader.Recognize("Multiple.jpg", NetBarcodeReader.Qrcode)
Dim data1 As String() = NetBarcodeReader.Recognize("Multiple.jpg", NetBarcodeReader.Datamatrix)
For Each result As String In data
Console.WriteLine(result)
Next
For Each result1 As String In data1
Console.WriteLine(result1)
Next
Console.ReadKey()
End Sub
End Module
