Barcode Scanning in C#.NET

This guide tells users how to read linear & 2D barcode with RasterEdge .NET Imaging SDK and Barcode Reader using Visual C# sample codes. (For VB.NET developers, please go to Barcode Reading for VB.NET. Want to view Image and document in Winforms or Web applications, please go to Reading Barcode in Winforms and Web Document Image Reading.)

Run Microsoft Visual Studio (2005 or later version);
Create a project with programming language - Visual C#;
Add RasterEdge.DotNetImaging.dll & RasterEdge.DotNetImaging.BarcodeScan.dll to your Visual C# applications;
Call RasterEdge .NET Image Namespace:


using System;
using RasterEdge.Imaging.Basic.Core;
using RasterEdge.Imaging.Basic;
using RasterEdge.Imaging.Barcode.Scanner;
using System.Diagnostics;
using System.Collections.Generic;
using System.Drawing;

Read Barcode Method

Rasteredge provides following method for user to read barcode.


public static string[] Scan(string imageFile, BarcodeType barcodeType);
public static string[] ScanRegions(string imageFile, BarcodeType barcodeType, Setting settings);

Read Barcode Example

The following code shows how to read a barcode:


public static void ReadBarcodeDemo()
{
string fileName = FolderName + "Sample.png";          

string[] datas = BarcodeScanner.Scan(fileName, BarcodeType.Code128);

foreach (string data in datas)
{
Debug.WriteLine(data);
}
}


public static void ReadBarcodeFormRegionsDemo()
{
string fileName = FolderName + "Sample.png";

            
Setting set = new Setting();
set.Code39IncFindPtp = false;
//set.IsMaxOneBarcodePerPage = true;

List<SRegion> areas = new List<SRegion>();
PointF topLeftPoint = new PointF(0, 0);
PointF bottomRightPoint = new PointF(200, 200);
SRegion area = new SRegion(topLeftPoint, bottomRightPoint);

set.setScanRegions(areas);


string[] datas = BarcodeScanner.ScanRegions(fileName, BarcodeType.Code128, set);

foreach (string data in datas)
{
Debug.WriteLine(data);
}

}
