如何使用不同的掃描模式讀取二維碼

using System.Linq;

 // Load the image

// Create scan input using Only Basic Scan mode
var input = new QrImageInput(bmp, QrScanMode.OnlyBasicScan);

// Get the result
var result = new QrReader().Read(input).FirstOrDefault();

// Save the output to a text file
File.WriteAllText("basic-scan-output.txt", result.Value);

// Scan and read all QR codes

// Initialize a counter to track the number of QR codes
int count = 1;

// Loop through each discovered QR code
foreach (var result in results)
{
    Console.WriteLine($"QR {count}: {result.Value}");
    count++;
