GDI+绘制竖向文本

可通过

 StringFormat sF = new StringFormat(StringFormatFlags.DirectionVertical);

以及使用

  g.DrawString(s, f, Brushes.Black, rf,sF);

来绘制竖向文本

 

 

 private void Form1_Paint(object sender, PaintEventArgs e)
        {
            Graphics g = e.Graphics;
            Font f = new Font("Aris", 15, FontStyle.Italic);
            string s = "this is my name ,and what";
            StringFormat sF = new StringFormat(StringFormatFlags.DirectionVertical);
            SizeF sf = g.MeasureString(s, f, 100);
            RectangleF rf = new RectangleF(20, 20, sf.Width, sf.Height);
            g.DrawRectangle(Pens.Red, rf.Left, rf.Top, rf.Width, rf.Height);
            g.DrawString(s, f, Brushes.Black, rf,sF);
         
        }
