C#에서 QR 코드 값을 읽는 방법

using IronQr;
using IronSoftware.Drawing;

AnyBitmap inputImage = AnyBitmap.FromFile("sample.jpg");

QrImageInput imageInput = new QrImageInput(inputImage);
QrReader reader = new QrReader();
IEnumerable<QrResult> results = reader.Read(imageInput);

QrResult result = results.First();

// Decoded text content of the QR code
Console.WriteLine($"Value: {result.Value}");

// Parsed URL — populated when Value is a valid URL, null otherwise
Console.WriteLine($"Url:   {result.Url}");

// Corner coordinates of the QR code in the image [TL, TR, BL, BR]
string[] labels = { "Top-Left", "Top-Right", "Bottom-Left", "Bottom-Right" };
for (int i = 0; i < result.Points.Length; i++)
{
    Console.WriteLine($"{labels[i]}: ({result.Points[i].X}, {result.Points[i].Y})");
}
