读取条形码
我们可以使用 BarcodeReader 类读取条形码。最简单的方法是 "BarcodeReader.Read "方法，如上图所示。
请注意 "BarcodeReaderOptions"（条码阅读器选项）中设置的各种选项，这些选项允许您自定义读取速度、读取强度、在读取到一个条码后停止扫描以节省时间、指定要搜索的特定条码类型以及使用多线程等其他自定义选项。

// 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
