method for text formatting at C#

all. I'm writing a programm at C# .NET. I have a richtextBox in my form(Windows Form). I open a text file and put text in richtextBox. I need to format selected text with FontDialog. But it's changed all text, not selected. What method can be applied, to FontDialog changed only selected text?

My code:

 if (fontDialog1.ShowDialog() != DialogResult.Cancel)
        {
            if (richTextBox1.SelectedText.Length > 0)
            {
                richTextBox1.Font = fontDialog1.Font;
                richTextBox1.ForeColor = fontDialog1.Color;
            }

thanks.

User RichTextBox.SelectionFont property

if (fontDialog1.ShowDialog() != DialogResult.Cancel)
    {
        if (richTextBox1.SelectedText.Length > 0)
        {
            richTextBox1.SelectionFont = fontDialog1.Font;
            richTextBox1.SelectionColor = fontDialog1.Color;
        }

The documentation for SelectedText gives some good help

richTextBox1.SelectionFont = fontDialog1.Font
richTextBox1.SelectionColor = fontDialog1.Color;

You need to use the SelectionFont & SelectionColor properties of the richtextBox: because the properties you are using apply to the full contents of the control

if (fontDialog1.ShowDialog() != DialogResult.Cancel)
        {
            if (richTextBox1.SelectedText.Length > 0)
            {
                richTextBox1.SelectionFont = fontDialog1.Font;
                richTextBox1.SelectionColor = fontDialog1.Color;
            }
