Edit a specific Line of a Text File in C#
the easiest way is : static void lineChanger(string newText, string fileName, int line_to_edit) { string[] arrLine = File.ReadAllLines(fileName); arrLine[line_to_edit – 1] = newText; File.WriteAllLines(fileName, arrLine); } usage : lineChanger(“new content for this line” , “sample.text” , 34);
