public void DrawRoundRect(Graphics g, Pen p, float X, float Y, float width, float height, float radius)

{

	System.Drawing.Drawing2D.GraphicsPath gp = new System.Drawing.Drawing2D.GraphicsPath();



	gp.AddLine(X + radius, Y, X + width - (radius * 2), Y);



	gp.AddArc(X + width - (radius * 2), Y, radius * 2, radius * 2, 270, 90);



	gp.AddLine(X + width, Y + radius, X + width, Y + height - (radius * 2));



	gp.AddArc(X + width - (radius * 2), Y + height - (radius * 2), radius * 2, radius * 2, 0, 90);



	gp.AddLine(X + width - (radius * 2), Y + height, X + radius, Y + height);



	gp.AddArc(X, Y + height - (radius * 2), radius * 2, radius * 2, 90, 90);



	gp.AddLine(X, Y + height - (radius * 2), X, Y + radius);



	gp.AddArc(X, Y, radius * 2, radius * 2, 180, 90);



	gp.CloseFigure();



	g.DrawPath(p, gp);

	gp.Dispose();

} 



private void pictureBox1_Paint(object sender, PaintEventArgs e)

{

	DrawRoundRect(e.Graphics, Pens.Black, 0, 0, pictureBox1.Width - 1, pictureBox1.Height - 1, 10);

}
