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 也有一個 ReadAsync 方法，用於多線程異步編程。
請注意，在 BarcodeReaderOptions 中有各種選項，讓您可以自訂您的讀取方式，使其更快速、記憶體使用更有效率，且更準確。
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
})
