SelectionFont、SelectedText、および SelectionColor の各プロパティと共に SelectionBullet プロパティを使用して、RichTextBox コントロール内に箇条書きリストを作成する方法を次のコード例に示します。この例では、richTextBox1 という名前の RichTextBox コントロールがフォーム上で作成されている必要があります。

Visual Basic

Private Sub 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:" + ControlChars.Cr
   ' 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" + ControlChars.Cr
   ' 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" + ControlChars.Cr
   richTextBox1.SelectionFont = New Font("Arial",
 12)
   richTextBox1.SelectionColor = Color.Purple
   richTextBox1.SelectedText = "Grapes" + ControlChars.Cr
   ' 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!"
End Sub
