Neodynamic Barcode Reader SDK是一款可以对.NET应用和ASP.NET网站添加条码识别和读取功能的高级开发包,可以从数字图像、 位图和扫描的文档等中识别读取多种一维线型条码。支持多种条码类型。

本文将简单介绍如何用Neodynamic Barcode Reader SDK实现条码的识别。

假设需对下图进行解码识别,我们知道这图片中包含了EAN-13码和Code-128码。可参考下面代码,对图片进行扫描识别,再获取控制台结果。

步骤:

  1. 打开Visual Studio创建应用程序
  2. 添加引用到System.Drawing.dll 和Neodynamic.SDK.BarcodeReader.dll
  3. 控制台方法编写,可参考下面代码。
VB
'Add the Barcode Reader namespace reference
Imports Neodynamic.SDK.BarcodeReader
'Create a BarcodeReader object
Dim myReader As New BarcodeReader()
'Add the barcode symbologies to be recognized
myReader.Symbology.Add(Symbology.Ean13)
myReader.Symbology.Add(Symbology.Code128)
'Set max num of barcode symbols to be detected
myReader.Hints.MaxNumOfBarcodes = 2
'Scan the source image and get result
Dim results As List(Of BarcodeScanResult) = myReader.Scan("c:\barcode_sample.jpg")
'Display scan result
For Each result As BarcodeScanResult In results
	Console.WriteLine("Barcode Type: " & result.Symbology.ToString())
	Console.WriteLine("Barcode Data: " + result.Text)
	Console.WriteLine("=============")
Next

C#

//Add the Barcode Reader namespace reference
using Neodynamic.SDK.BarcodeReader;
//Create a BarcodeReader object
BarcodeReader myReader = new BarcodeReader();
//Add the barcode symbologies to be recognized
myReader.Symbology.Add(Symbology.Ean13);
myReader.Symbology.Add(Symbology.Code128);
//Set max num of barcode symbols to be detected
myReader.Hints.MaxNumOfBarcodes = 2;
//Scan the source image and get result
List<BarcodeScanResult> results = myReader.Scan(@"c:\barcode_sample.jpg");
//Display scan result
foreach (BarcodeScanResult result in results)
{
    Console.WriteLine("Barcode Type: " + result.Symbology.ToString());
    Console.WriteLine("Barcode Data: " + result.Text);
    Console.WriteLine("=============");
}
