走近VB.Net（七）在窗体上画图

Dim gp As Graphics = e.Graphics

Dim newpen As New Pen(Color.Black, 5)

gp.DrawBezier(newpen, 10, 20, 70, 80, 123, 233, 23, 45)

End Sub

你也可以在一屏之内同时进行多次绘图，如下：

Protected Overrides Sub OnPaint(ByVal e As PaintEventArgs)

Dim i As Integer

Dim gp As Graphics = e.Graphics

For i = 1 To 10

Dim newpen As New Pen(color.FromARGB(i * 25, i * 25, i * 25), 5)
