让文字竖着显示

[NealXX]

在WinForm程序中，怎样才能让Label的Text竖着显示,或者说让Label控件顺时针旋转90°

[dancingbit]

把宽度调到只有容纳一个字，高度加大。

[NealXX]

字没旋转。。

[柳晛]

不知道label能不能重写。

[pengalwin]

我也想实现这玩意

[dancingbit]

在Paint事件中，使用DrawString绘制文本。

[NealXX]

不行的话 看看能不能自己画， 自己画太麻烦了

你想要什么旋转呢？

[markhao]

都旋转...哈哈.

[风之影子]

13楼的是旋转的自绘。

应该满足你需求了吧！

[dancingbit]

13L好快...

[markhao]

咋运行13L代码报14个错...

[markhao]

13L是专家级人物?

[NealXX]

差不多了 谢谢
