Answer 2

You can create a text file,and store data in.Using StreamWriter you can do it,or use SaveFileDialog.

//streamwriter
StreamWriter sr = new StreamWriter("file save path");
sr.Write(richTextBox1.Text);
sr.Close();

//or use savefiledialog
SaveFileDialog sv = new SaveFileDialog();
if(sv.ShowDialog()==Dialog.Result)
{
richTextBox1.SaveFile("file save path");
}
