You might try something like:
private void button1_Click(object sender, EventArgs e)
openFileDialog1.Filter = "Text Files|*.txt";
Stream sr = openFileDialog1.OpenFile();
byte buff = new byte;
sr.Read(buff, 0, 60);
This does not take into account end of line or end of stream and just writes the output to the debuggin window.
What you don't know can hurt you!
