How can I view text file in notepad on button click?

Question

The code:

private void viewLogFileToolStripMenuItem_Click(object sender, EventArgs e)
{
     string path_log = Path.GetDirectoryName(Application.LocalUserAppDataPath) + @"\log";
     string logger_file = @"\logger.txt";
     string LoggerFileName = Path.Combine(path_log, logger_file);    
}

I want when I click the menu item it will open the LoggerFileName automatic in notepad and show me the notepad window .

I don't like the number `3`, so +1 for you to make it `2` and hope no one will down vote you! — King King, Jun 08 '13 at 16:30

if txt file default open application set as notepad you can open it as below

System.Diagnostics.Process.Start(LoggerFileName);

below will open notepad with given file

System.Diagnostics.Process.Start("notepad.exe", LoggerFileName);

Note :

string LoggerFileName = Path.Combine(
                      Path.GetDirectoryName(Application.LocalUserAppDataPath), 
                     "log", 
                     "logger.txt");

So basically rip the answers out of http://stackoverflow.com/questions/4055266/open-a-file-with-notepad-in-c-sharp ? – It'sNotALie. Jun 08 '13 at 16:17
the first usually opens file with notepad but in some case if txt file is opened by another application as default, that application will show the file content. – King King Jun 08 '13 at 16:18
`"notepad"` can also work as well as `"notepad.exe"` :), just some helpful comment for others. :) – King King Jun 08 '13 at 16:23

Have you even researched this at all?

private void viewLogFileToolStripMenuItem_Click(object sender, EventArgs e)
        {
            string path_log = Path.GetDirectoryName(Application.LocalUserAppDataPath) + @"\log\";
            string logger_file = @"\logger.txt";
            string LoggerFileName = Path.Combine(path_log, logger_file);
            Process.Start(Path.Combine(Environment.SystemDirectory, @"\notepad.exe"), LoggerFileName);
        }

All you needed to google was really "get notepad path c#" and "start process c#".

Ok i tried but for some reason LoggerFileName contain only "\\logger.txt" why is that ? Therefore it cant find the file . – joneK Jun 08 '13 at 16:19
@newStackExchangeInstance along with auto foreground window and a button. – Prix Jun 08 '13 at 16:19
yes, I've just made a statement :) – King King Jun 08 '13 at 16:19
@joneK Give me the value of `MessageBox.Show(Path.GetDirectoryName(Application.LocalUserAppDataPath) + @"\log");` – It'sNotALie. Jun 08 '13 at 16:20
The Path_Log contain : "C:\\Users\\bout0_000\\AppData\\Local\\ScreenVideoRecorder\\ScreenVideoRecorder\\log" and i see on my hard disk this directory and the log file inside – joneK Jun 08 '13 at 16:21
@joneK Slight bug with your string, should be fixed now. – It'sNotALie. Jun 08 '13 at 16:22

There is the Process class in the .Net framework.

Use it with ProcessStartInfo.UseShellExecute set to true. Then you can "start" the .txt file, and the user could've chosen it's favorite editor. The default, however, would be NotePad anyway.

What about

   private void viewLogFileToolStripMenuItem_Click(object sender, EventArgs e)
   {
        string path_log = Path.GetDirectoryName(Application.LocalUserAppDataPath) + @"\log";
        string logger_file = @"\logger.txt";
        string LoggerFileName = Path.Combine(path_log, logger_file);
        string notepadPath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.System),"notepad.exe")
        Process.Start(notepadPath,LoggerFileName);
    }

?
