异步读取 BarCode
我们可以使用BarcodeReader类读取条形码。 最简单的方法是使用BarcodeReader.Read方法。 IronBarcode 还具有用于多线程异步编程的ReadAsync方法。
请注意,在BarcodeReaderOptions中可以选择多种选项,让您的读取更快速、更节省内存,并且更准确。
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
