Getting Started with the QR Code Scanner API
For this tutorial, we’ll use Aspose.BarCode for .NET, an incredibly versatile library that makes QR code scanning a breeze. Getting started is super simple - just install the NuGet package:
PM> Install-Package Aspose.BarCode
Scanning a QR Code: The Simple Way
Here’s how easy it is to scan a QR code in C#:
- Create a BarCodeReader object
- Set up the decode type
- Retrieve the QR code’s content
Don’t worry about the technical details - the code does all the heavy lifting for you!
File-based QR Code Scanning
We can easily scan a QR code by following the steps below:
- Initialize an object of the [BarCodeReader][https://reference.aspose.net/barcode/aspose.barcode.barcoderecognition.barcodereader/] class along with the [DecodeType][https://reference.aspose.net/barcode/aspose.barcode.barcoderecognition.decodetype/] parameter.
- Create an instance of the [BarCodeResult][https://reference.aspose.net/barcode/aspose.barcode.barcoderecognition.barcoderesult/] class.
- Scan the QR code and get the result text.
The following code sample shows how to scan a QR Code in C# from an image file.
Stream-Based QR Code Scanning
Need to read a QR code from a stream? No problem! The process is almost identical to file-based scanning. Just initialize your reader, set the decode type, and grab the results.
- Declare an instance of the BarcodeReader class and set the DecodeType property.
- Instantiate a BarCodeResult type object.
- Scan the QR Code and retrieve the output text.
