Your question is not clear enough. If the problem with extracting text from the PDF using iTextSharp see the following discussion: http://stackoverflow.com/questions/4711134/itextsharp-text-extraction Note that I didn't try iTextSharp myself before but I am getting the text from PDF files using PDFdocument features using leadtools. If the problem is with getting the numeric text (numbers) from the original string try this code: /****************************************************/ StringBuilder sb = new StringBuilder(); sb.Append(PH NO 456456121); int _lastspaceindex = sb.ToString().LastIndexOf(' '); string numeric_str = sb.ToString().Substring(_lastspaceindex sb.Length - _lastspaceindex).Trim(); Console.WriteLine(numeric_str); /****************************************************/

Hi Shrikesh Kale Sorry am confused what is you trying. First I tell you StringBulider like a string (No same some difference string and stringBulider). I think its no important difference. I make a simple example and data in stringBulider. StringBuilder myString = new StringBuilder(123); while (Console.ReadLine() == a) { myString.Append(234); //Average loop times 4~ or more } myString.Append(345); if I want get values of 345 then how to get????? if data values is fixed then you get using inexof and all that.
