如何为 TabPage 控件分配自定义背景色或背景图像？
如何在 Visual Studio C# 2010 中为选项卡页控件分配背景图像？我可以分别为每个选项卡提供背景图像，但我不能为整个选项卡页控件提供背景图像，因为选项卡页控件的一部分保留不同的背景，并且每个选项卡页都有良好且精细的背景。
这是我的表单的图片：

包含选项卡的标题区域不是选项卡页的一部分。它是父
TabControl的一部分，由 Windows 自动为您绘制。如果你想改变它的外观，你就必须自己画它。这就是所谓的所有者绘图，这并不是一项简单的任务，尤其是对于像这样的复杂控件。对于初学者来说，您不能只使用
OwnerDrawFixed，因为它只允许您自定义绘制选项卡的内容（例如，更改字体）。您需要绘制整个选项卡控件。我无法想象您想要这样做的充分理由，但您会在网上找到一些可能帮助您入门的示例。例如：
The header area that contains the tabs is not part of your tab page. It's part of the parent
TabControl, which is automatically drawn for you by Windows.If you want to change how it looks, you'll have to draw it yourself. That's called owner-drawing, and it's not exactly a trivial undertaking, especially for a complicated control like this one. For starters, you can't just use
OwnerDrawFixed, because that just allows you to custom draw the contents of the tabs (for example, to change the font).
