How to Scan a Barcode Image and Extract the Data in C# .NET Framework

Barcode scanning is a crucial part of many business workflows, but it can be a difficult feature to implement if you don’t take the right approach. Setting up such a system from scratch is a sure ticket to frustration and inaccuracy, as can be confirmed even by commercial-grade grocery store barcode scanners. You need a solution that can deal with skewed, improperly printed, wrinkle up barcodes, and deal with them fast!

To set up, we will bring in our package using NuGet:

Install-Package Cloudmersive.APIClient.NET.Barcode -Version 3.0.1

Now we can go ahead and call our barcode function, feeding in our input image:

using System;
using System.Diagnostics;
using Cloudmersive.APIClient.NET.Barcode.Api;
using Cloudmersive.APIClient.NET.Barcode.Client;
using Cloudmersive.APIClient.NET.Barcode.Model;
namespace Example
{
public class BarcodeScanImageExample
{
public void main()
{
// Configure API key authorization: Apikey
Configuration.Default.AddApiKey("Apikey", "YOUR_API_KEY");
// Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
// Configuration.Default.AddApiKeyPrefix("Apikey", "Bearer");
var apiInstance = new BarcodeScanApi();
var imageFile = new System.IO.Stream(); // System.IO.Stream | Image file to perform the operation on.  Common file formats such as PNG, JPEG are supported.
try
{
// Scan an image for a barcode and turn the result.  Supported barcode types include AZTEC, CODABAR, CODE_39, CODE_93, CODE_128, DATA_MATRIX, EAN_8, EAN_13, ITF, MAXICODE, PDF_417, QR_CODE, RSS_14, RSS_EXPANDED, UPC_A, UPC_E, All_1D, UPC_EAN_EXTENSION, MSI, PLESSEY, IMB
BarcodeScanResult result = apiInstance.BarcodeScanImage(imageFile);
Debug.WriteLine(result);
}
catch (Exception e)
{
Debug.Print("Exception when calling BarcodeScanApi.BarcodeScanImage: " + e.Message );
}
}
}
}

And there you have it! Easy as pie.
