[Kath_Fish]

hey....i got some problem in ReadLines method

  string filePath = @"c:\Users\Fish\Desktop\fyp-coding\Data.txt";
                    string line;

                 if (File.Exists(filePath))
                    {
                        StreamReader file = null;
                        try
                        {
                            file = new StreamReader(filePath);



                            while ((line= file.ReadLine())!= null)
                            {
                                textBox7.Text = line;

                            }

                        }

                        finally
                        {
                            if (file != null)
                            file.Close();
                        }

                    }

When i use this coding...it only show the last line to me. I want show the previous line, how to do it?

string filePath = @"c:\Users\Fish\Desktop\fyp-coding\Data.txt";
String[] myLines = File.ReadAllLines(filePath);
textBox7.Text = myLines[myLines.Length - 2];

what is different between readLine, readAllLine and readToEnd...?

[Momerath]

ReadLine gets one line from the file
ReadAllLines reads all the lines and returns an array of strings.
ReadToEnd reads the entire file returning it as one string.
