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.
