根据传入的文字生成图片 并保存

public void SavePhoneImg(string Phone, string path)
        {
            System.Drawing.Bitmap image = new System.Drawing.Bitmap(135, 25);
            Graphics g = Graphics.FromImage(image);
            try
            {
                Font font = new System.Drawing.Font("楷体", 15, (System.Drawing.FontStyle.Bold));
                System.Drawing.Drawing2D.LinearGradientBrush brush = new System.Drawing.Drawing2D.LinearGradientBrush(new Rectangle(5, 5, image.Width, image.Height), Color.Black, Color.Black, 1.2f, true);
                g.DrawString(Phone, font, brush, 2, 0);
                //画图片的边框线 
                g.DrawRectangle(new Pen(Color.Silver), 0, 0, image.Width - 1, image.Height - 1);
                System.IO.FileStream ms = new System.IO.FileStream(path, FileMode.Create);
                image.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
            }
            finally
            {
                g.Dispose();
                image.Dispose();
            }
        }
