如何根据从组合框中选择的角度旋转标签

我想根据用户从组合框中选择角度来旋转标签。

例如

label1是标签名称。

cboRotate是具有项目集合的组合框，如45,90,135,180 ...



一旦用户在组合框中选择45，label1必须旋转到45度。

感谢您的时间。

Hi,
I want to rotate label as per user select angle degree from combobox.
e.g.
label1 is label name.
cboRotate is combobox having item collection like 45,90,135,180...

Once user select 45 in combobox, label1 must rotate to 45 degree.
Thanks for your time.
