if (this.TextEditor.Selection.IsEmpty)

else

以下是一些例子 Windows 更改字体和字体颜色(不是WPF)
richTextBox1.SelectionFont = new Font("Tahoma", 12, FontStyle.Bold);
richTextBox1.SelectionColor = System.Drawing.Color.Red;
以下是另一个示例(非WPF):
private void WriteTextToRichTextBox()
{
// Clear all text from the RichTextBox;
richTextBox1.Clear();
// Set the font for the opening text to a larger Arial font;
richTextBox1.SelectionFont = new Font("Arial", 16);
// Assign the introduction text to the RichTextBox control.
richTextBox1.SelectedText = "The following is a list of bulleted items:" + "\n";
// Set the Font for the first item to a smaller size Arial font.
richTextBox1.SelectionFont = new Font("Arial", 12);
// Specify that the following items are to be added to a bulleted list.
richTextBox1.SelectionBullet = true;
// Set the color of the item text.
richTextBox1.SelectionColor = Color.Red;
// Assign the text to the bulleted item.
richTextBox1.SelectedText = "Apples" + "\n";
// Apply same font since font settings do not carry to next line.
richTextBox1.SelectionFont = new Font("Arial", 12);
richTextBox1.SelectionColor = Color.Orange;
richTextBox1.SelectedText = "Oranges" + "\n";
richTextBox1.SelectionFont = new Font("Arial", 12);
richTextBox1.SelectionColor = Color.Purple;
richTextBox1.SelectedText = "Grapes" + "\n";
// End the bulleted list.
richTextBox1.SelectionBullet = false;
// Specify the font size and string for text displayed below bulleted list.
richTextBox1.SelectionFont = new Font("Arial", 16);
richTextBox1.SelectedText = "Bulleted Text Complete!";
}
var selection = myRichTextBox.Selection;
if (!selection.IsEmpty)
selection.ApplyPropertyValue(TextElement.FontSizeProperty, 10.0);
