讀取條碼
我們可以使用 BarcodeReader 類別來讀取條碼。最簡單使用的方法是 BarcodeReader.Read 方法，如上所示。
請注意，在 BarcodeReaderOptions 中設定的各種選項，它們允許您自訂讀取速度、更密集的讀取、在找到一個條碼後停止掃描以節省時間、指定要搜尋的特定條碼類型，以及使用多執行緒，還有其他自訂選項。

// Reading a barcode is easy with IronBarcode.
// Read from a File, Bitmap, Image, or Stream:
var resultFromFile = BarcodeReader.Read(@"file/barcode.png"); // From a file
var resultFromBitMap = BarcodeReader.Read(new Bitmap("barcode.bmp")); // From a bitmap
var resultFromAnyBitmap = BarcodeReader.Read(new AnyBitmap("barcode.bmp")); // From an Anybitmap
var resultFromImage = BarcodeReader.Read(Image.FromFile("barcode.jpg")); // From an image
var resultFromStream = BarcodeReader.Read(myStream); // From a stream
// PDFs are more intricate and must be read using ReadPdf:
var resultFromPdf = BarcodeReader.ReadPdf(@"file/mydocument.pdf");Imports IronBarCode
