DrawToBitmap 方法有下列限制：The DrawToBitmap method has the following limitations:

  • 可能會針對大型點陣圖擲回 ArgumentException。An ArgumentException might be thrown for large bitmaps. 允許的大小上限會因電腦而異。The maximum allowable size varies by machine.

  • DrawToBitmap 不支援 Windows XP Tablet PC Edition 2005 作業系統的 Ink 控制項。DrawToBitmap does not support the Ink controls for the Windows XP Tablet PC Edition 2005 operating system.

  • 如果 TextBox 的 Visible 屬性設定為 [false]，DrawToBitmap 不會繪製子 TextBox。DrawToBitmap does not draw a child TextBox if the Visible property of the TextBox is set to false.

  • 容器內的控制項會以反向順序呈現。Controls inside containers are rendered in reverse order.

  • RichTextBox的 DrawToBitmap 無法完全正常運作;只繪製點陣圖的框線。DrawToBitmap is not fully functional for the RichTextBox; only the border of a bitmap is drawn.
