我把代码修改了一下，还是不行。

Dim x As Integer = args(0)
Dim y As Integer = args(1)
Dim paint As WinForm.Painter = args(2)

Dim graphics As Graphics = paint.Graphics

using p As New Pen(Color.Green, 10)
p.StartCap = Drawing2D.LineCap.Round
p.EndCap = Drawing2D.LineCap.Round
p.LineJoin = Drawing2D.LineJoin.Round
graphics.SmoothingMode = SmoothingMode.AntiAlias

\'graphics.DrawLine(p, px, py,x, y)
Dim w As Integer = Math.Abs(px-x)
Dim h As Integer = Math.Abs(py-y)
graphics.DrawRectangle(p,px,py,w,h)
End using
paint.Repaint
