使用下面代码可以实现文本换行操作

using (Font font = new Font("方正黑体简体", 10F, FontStyle.Regular))
            using (SolidBrush brush = new SolidBrush(Color.Black))
            using (Pen pen = new Pen(Color.Black))
            {
                StringFormat sf = new StringFormat();

                sf.Alignment = StringAlignment.Center;

                sf.LineAlignment = StringAlignment.Center;
