該功能允許使用者將當前執行緒暫停指定的毫秒時間。
這有助於在程式或應用程式執行時遇到卡住情況時讀取大型輸入文件。
探索使用IronOCR的非同步OCR操作。using IronOcr;
using System.Threading;
// Opens a Large PDF which may need to be cancelled early
IronTesseract ocrTesseract = new IronTesseract() { Language = OcrLanguage.English };
using var ocrInput = new OcrInput();

// Starts a read on the PDF using IronOCR
OcrReadTask ocrRead = ocrTesseract.ReadAsync(ocrInput);
Thread.Sleep(1000); // Time passes...
// Cancellation Example:
ocrRead.Cancel();
ocrRead.Wait();
