GDI+ 绘制多行文本，自动换行。

1，主要利用MessageString（）这个函数来实现自动换行。截图如下：

 

代码如下：

  //绘制有边框的字体，并自动换行
        private void Form1_Paint(object sender, PaintEventArgs e)
        {
            Graphics g = e.Graphics;
            Font f = new Font("Aris", 15, FontStyle.Italic | FontStyle.Strikeout);
            string s = "this is my name ,and what about you ,ok no problems,every is ok,something is goods,program.cs ,I want to make susccfjdkjk,grapeBunch/bmp";
            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);
         
            
        }
