hi, To do this you have to read whole file first using File.ReadAllText methods try.. string text = System.IO.File.ReadAllText(@"D:	extfile.txt"); var allText = text.Split(new string[] { "
" }, StringSplitOptions.None); for (var i = 0; i { string line = allText[i]; string nextline = allText[i + 1]; // put here validation if it is not exceed the array limit. //do your code. } hope this will help you.

If you don't want to read the second line at all if it starts with a ';' then try this: using (StreamReader sr = new StreamReader("atul.txt")) { int i; int c = (int)';'; string line = null; while ((i = sr.Peek()) > 0) { if (i == c) break; line = sr.ReadLine(); // code to insert line data into database } }

Something like this perhaps? using (StreamReader sr = new StreamReader("somefile.txt")) { string line; while ((line = sr.ReadLine()) != null) { if (line.Contains(";")) continue; // code to insert line data into database } } If the '; 'will only appear as the first character of a line, you could also use line.StartsWith(";").
