異步讀取條碼
我們可以使用 BarcodeReader 類別來讀取條碼。最簡單的方法是使用 BarcodeReader.Read 方法。IronBarcode 還提供了一個 ReadAsync 方法，這讓你可以在 IronBarcode 中使用多線程異步編程項目。
請注意 BarcodeReaderOptions 中設置的各種選項，這些選項允許你自定義讀取過程，使其更快、更密集、在讀取到一個條碼後停止掃描以節省時間、指定要搜索的特定條碼類型以及使用多線程等其他自定義選項。
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
})
