異步讀取條碼
我們可以使用 BarcodeReader 類別讀取條碼。 使用 BarcodeReader.Read 方法是最簡單的方法。 IronBarcode 還有一個用於多執行緒異步程式設計的 ReadAsync 方法。
請注意 BarcodeReaderOptions 中的各種選項，這些選項允許您自定義讀取方式，使其更快、更節省記憶體且更準確。
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
})
