Здесь мы покажем Вам, как использовать методы поиска и замены.
Наша задача - найти слово - "Bean" и изменить на - "Joker". Мы будем использовать обычные выражения (Regex).
с помощью SautinSoft.Document;
DocumentCore dc = new DocumentCore();
DocumentCore является корневым классом, он представляет сам документ.
Regex regex = new Regex(@"bean", RegexOptions.IgnoreCase);
//Find "Bean" and Replace everywhere to "Joker"
foreach (ContentRange item in dc.Content.Find(regex))
{
item.Replace("Joker");
}
string savePath = Path.ChangeExtension(loadPath, ".replaced.pdf");
dc.Save(savePath, new PdfSaveOptions());
System.Diagnostics.Process.Start(savePath);
Загрузите полученный PDF-документ: Replaced.pdf
