Simplest way of adding a '' to each line of a rich text box

Question

Hi All In finishing off a bit of test code I'm doing I have some results shoved to a rich text box. I am trying to add a '' to the end of each line I am doing the following StreamWriter sw = new StreamWriter(filePutter.FileName); sw.WriteLine(Pitstop 2.0 Transparent Data  + DateTime.Now.ToString() +  Serial Number: + txtSerialNumberRead.Text + ); sw.Write(rtbTransparentLog.Text); this while it saves the data does not give what I need i.e.: data it gives data The rtbox is updated with rtbTransparentLog.Text +=+ myComPort.ReadLine(); by placing the comma after rtbTransparentLog.Text +=myComPort.ReadLine()+; means the same still happens due to the line feed stuck on the end. Any quickways if getting it in there? Glenn

If you don't put the commas into the RTB to start with then you could put them in subsequently with code like this: string[] lines = rtbTransparentLog.Lines; for (int i = 0; i { lines[i] += ; } rtbTransparentLog.Lines = lines; Or if you just want to write a single comma separated line to the file you could do: string combined = String.Join( rtbTransparentLog.Lines);
