Refer this example
private void ModifySelectedText()
{
// Determine if text is selected in the control.
if (richTextBox1.SelectionLength > 0)
{
// Set the color of the selected text in the control.
richTextBox1.SelectionColor = Color.Red;
// Set the font of the selected text to bold and underlined.
richTextBox1.SelectionFont = new Font("Arial",10,FontStyle.Bold | FontStyle.Underline);
// Protect the selected text from modification.
richTextBox1.SelectionProtected = true;
}
}
