Read dynamic textstream step by step

ghoshdatta.m

Hello forum, I want to display the input of a logfile in a textbox. The difficulty is that the logfile grows and the content of the textbox should also display the new entries in realtime. I do not want to read the whole content of the logfile and display it in the textbox. What I am looking for is to read the stream till "readline = null" and then try to read every x seconds from that position on. Does anyone know if that is possible? Thanks in advance, MG

One problem with that code: while(sr.Peek() != -1) //Peek = -1 has basically the same effect as EOF { buffer = sr.ReadLine(); } will leave only the last line of text in buffer. I usually use buffer = sr.ReadToEnd(); instead.

You're going to most likely run into issues with the file being in use if another program is using it but.. StreamReader sr = new StreamReader("c:\\file.txt"); string buffer; while(sr.Peek() != -1) //Peek = -1 has basically the same effect as EOF { buffer = sr.ReadLine(); } sr.Close(); if(buffer != txtBox.text) //check if the last line in the log is the same as the last time { txtBox.text = buffer; }
