如何在 C# 中讀取 QR code 類型

using IronQr;
using IronQr.Enum;
using System.Drawing;

// Import an image containing QR codes
var inputImage = Image.FromFile("sample.jpg");

// Load the asset into a QrImageInput object
QrImageInput imageInput = new QrImageInput(inputImage);

// Create a QR Reader object
QrReader reader = new QrReader();

// Read all embedded QR codes from the image
IEnumerable<QrResult> results = reader.Read(imageInput);

// Route processing based on the detected QR code format
foreach (QrResult result in results)
{
    switch (result.QrType)
    {
        case QrEncoding.QRCode:
            Console.WriteLine($"Standard QR Code: {result.Value}");
            break;
        case QrEncoding.MicroQRCode:
            Console.WriteLine($"Micro QR Code: {result.Value}");
            break;
        case QrEncoding.RMQRCode:
            Console.WriteLine($"RMQR Code: {result.Value}");
            break;
        default:
            Console.WriteLine($"Other format ({result.QrType}): {result.Value}");
            break;
    }
}
