<TabControl>

            <TextBlock>Content for Tab 1.</TextBlock>

            <TextBlock>Content for Tab 2.</TextBlock>

            <TextBlock>Content for Tab 3.</TextBlock>

        </TabControl>

TabControl 隐式地用它的TabItem类型包装每一个项。由于没有一个显式的TabItem，就没有办法产生相应的标签。

            <TabItem Header="Tab 1">
