我想在VB.Net中画一个圆圈

Private Sub PictureBox1_Paint(ByVal sender As System.Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles PictureBox1.Paint
    e.Graphics.DrawEllipse(Pens.AliceBlue, New Rectangle(New Point(0, 0), New Size(PictureBox1.Width, PictureBox1.Height)))


End Sub

我想在VB.Net,.Net版本4中绘制一个圆圈.
没有任何东西出现在paintbox中.

e.Graphics.DrawEllipse(Pens.AliceBlue,e.ClipRectangle);

它对我有用.
您也可以尝试使用：

e.Graphics.DrawEllipse(
    Pens.AliceBlue,
    0, 0,
    pictureBox1.Width-1, pictureBox1.Height-1);

要么

Rectangle rect = e.ClipRectangle;
rect.Inflate(-1, -1);
e.Graphics.DrawEllipse(Pens.AliceBlue, rect);
