Hi Bobi, Try this code, to read text in text file using file streamreader, var fileStream = new FileStream(@ "c:\file.txt" , FileMode.Open, FileAccess.Read); using (var streamReader = new StreamReader(fileStream, Encoding.UTF8)) { textBox1.Text= streamReader.ReadToEnd(); }

I still don't understand my dear friend. Please type more. Please tell EVERYTHING. Assuming you are having a windows forms application, you can do something like: String strFilename = "C:	emp\somefile.txt"; // put your filename here. txtFileContents.Text = File.ReadAllText(strFilename);

Dear Friend, it is ONLY you who is aware of your situation. We are the people very limited imagination (or atleast I am)! Could you please elaborate a bit? What database, what file? which duplicates? Any sample data? anything to look at and understand what you want to achieve?
