[VB.NET]请大家指教！！！

请大家指教！！！ 我在窗体上画好了一个椭圆，怎样实现让它任意角度旋转？ __________________________________________________________________________ Private Sub Form1_Paint(ByVal sender As Object,ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint Dim g As Graphics = e.Graphics g.RotateTransform(20) ''参数旋转的角度，此处为20度 g.DrawEllipse(Pens.Red,New Rectangle(100,50,200,100)) End Sub __________________________________________________________________________ 先谢谢楼上的，怎么才能给你加分？ __________________________________________________________________________
