C#资源管理器源码（带图标显示）,思归、橙子鸟、斑主请进,大家请进。

粘上一篇拙作，供大家评头论足。听说思归先生德才兼备。很想得到您的指正。看到橙子鸟先生的言论。很是新鲜，是非自有公论。我虽不赞美，却也不反感。特请橙子鸟先生进来一骂。但要骂的具体。例“xx句太臭”。我也喜欢菜鸟的吹棒，毕竟顺耳。总之，欢迎评头论足。吹棒使我信心倍加，骂声使我清醒努力。请问斑主，怎样才能增加分，我的分不多，还有好多问题请教大家。是不是发表点什么就可以得分。如认为我有所贡献，请多给我些分。先谢了。

顺便请教大家一个问题如下： float f1 = 2.11111f; dc.DrawString(f1.ToString(),font,brush,8,8); 在第一个参数中我想输出小数点后2位，而不是5位。该怎么截掉后3位。
