异步读取条形码
我们可以使用条码阅读器类读取条码。最简单的方法是 BarcodeReader.Read 方法。IronBarcode 还有一个 ReadAsync 方法，可让您使用 IronBarcode 进行多线程异步编程项目。
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。
using IronBarCode;
// Reading many images Asynchronously using ReadAsync
string[] imagePaths = new string[] { "image1.png", "image2.png" };
var resultsAsync = BarcodeReader.ReadAsync(imagePaths, new BarcodeReaderOptions() { ExpectMultipleBarcodes = true });
// Reading many PDFs Asynchronously using ReadPdfAsync
string[] pdfPaths = new string[] { "doc1.pdf", "doc2.pdf" };
var resultsPdfAsync = BarcodeReader.ReadPdfAsync(pdfPaths, new PdfBarcodeReaderOptions() { ExpectMultipleBarcodes = true, Scale = 3, DPI = 300 });Imports IronBarCode
' Reading many images Asynchronously using ReadAsync
Private imagePaths() As String = { "image1.png", "image2.png" }
Private resultsAsync = BarcodeReader.ReadAsync(imagePaths, New BarcodeReaderOptions() With {.ExpectMultipleBarcodes = True})
' Reading many PDFs Asynchronously using ReadPdfAsync
Private pdfPaths() As String = { "doc1.pdf", "doc2.pdf" }
Private resultsPdfAsync = BarcodeReader.ReadPdfAsync(pdfPaths, New PdfBarcodeReaderOptions() With {
.ExpectMultipleBarcodes = True,
.Scale = 3,
.DPI = 300
})
