You can also check this library, it is very promising... https://products.groupdocs.com/comparison/net . . . . . All you need to write is: . //Source and target files to be compared string source = @"source.docx"; string target = @"target.docx"; Comparer comparer = new Comparer(); //Compare two documents ICompareResult result = comparer.Compare(source, target, new ComparisonSettings()); . . . . Please let me know if that can solve your problem :)

Thanks varun could you see please send some exact codes to extract content from two pdf files and after splitting line by line need to compare the content and it should display the difference in output as my requirement is to validate two pdf content. In that have to validate fixed text,tag data validation and dynamic values. Would be helpful if I get code using iTextlibrary.
