Answer 1

            Bitmap bmp = new Bitmap();
            Graphics g = Graphics.FromImage(bmp);
            Font f=new Font();
            g.DrawString(str, f, Brushes.Black, 0, 0);

Answer 4

上面回答都是错的，楼主问得应该不是这个意思——把字符串画到BITMAP上。我想楼主应该是说，这个字符串信息代表着一幅图，如何把信息以实际代表的图输出。楼主，这要具体分析了，这些字符串如何得来的。规则是什么。？？？

楼主的图片做base64编码的吧

Answer 9

在VS2003里，我往资源里面添加一张图片，结果在Resource.resx的xml找到这个字符串，我想会不会是将图片转成字符串了？我想逆向转换，不知道能不能转成一张图片
   感谢大家的帮助，其实我不是想上面头几楼的那样，并不是将字符串画上去，而是将它直接转成图片；好像就是base64编码

Answer 10

我11楼写的不就是base64解码么，你解码一下看看是不是你要的图片

Answer 11

一般都是用 base64 的， 就按照11楼的就可以了
