Haven't tested it, but this should work...

FileStream file = new FileStream( "logfile.txt", FileMode.Open, FileAccess.Read)
file.Seek( previousEndPosition)
TextReader reader = new StreamReader( file);
while( (line = reader.ReadLine) != null)
{
...
}
previousEndPosition = file.Position;

Here is some old code of me that I once used to read lines from a logfile:

System.IO.FileSystemWatcher k_Watcher;

  long k_Position = 0;
  System.IO.FileStream k_File_Stream;
  System.IO.StreamReader k_Stream_Reader;

  private void k_Watcher_Start()
  {
   if (k_Watcher.EnableRaisingEvents == false)
   {
    k_File_Stream = new System.IO.FileStream(@"F:\Program Files\Ryzom\save\log_kaetemi.txt", System.IO.FileMode.Open, System.IO.FileAccess.Read);
    k_Stream_Reader = new System.IO.StreamReader(k_File_Stream);
    k_Position = k_File_Stream.Length;
    k_Stream_Reader.Close();
    k_File_Stream.Close();
    k_Watcher.EnableRaisingEvents = true;
   }
  }

  private void k_Watcher_End()
  {
   k_Watcher.EnableRaisingEvents = false;
  }

  private void k_Watcher_Changed(object sender, System.IO.FileSystemEventArgs e)
  {
   try
   {
    k_File_Stream = new System.IO.FileStream(e.FullPath, System.IO.FileMode.Open, System.IO.FileAccess.Read);
    k_Stream_Reader = new System.IO.StreamReader(k_File_Stream);
    if (k_Position < k_File_Stream.Length)
    {
     k_File_Stream.Position = k_Position;
     k_Watcher_NewData(k_Stream_Reader.ReadToEnd());
     k_Position = k_File_Stream.Position;
    }
    else
    {
     k_Position = k_File_Stream.Length;
    }
    k_Stream_Reader.Close();
    k_File_Stream.Close();
   }
   catch
   {
    k_InfoData.Text = "BUG AT: k_Watcher_Changed";
   }
  }

  private void k_Watcher_NewData(string k_Data)
  {

  }
