I’d like to add new line with text to my date.txt file, but instead of adding it into existing date.txt, app is creating new date.txt file..
TextWriter tw = new StreamWriter("date.txt"); // write a line of text to the file tw.WriteLine(DateTime.Now); // close the stream tw.Close();
I’d like to open txt file, add some text, close it, and later after clicking something: open date.txt, add text, and close it again.
So i can get:
Button pressed: txt opened -> added current time, then close it. Another button pressed, txt opened -> added text “OK”, or “NOT OK” in the same line, then close it again.
So my txt file will look like that:
2011-11-24 10:00:00 OK 2011-11-25 11:00:00 NOT OK
How can i do this? Thanks!
You could do it easily using
If you need newline
File.AppendAllText("date.txt", DateTime.Now.ToString() + Environment.NewLine);
Anyway if you need your code do this:
TextWriter tw = new StreamWriter("date.txt", true);
with second parameter telling to append to file.
Check here StreamWriter syntax.
