嗨,我有一个存储字符串和整数的查找类型.
static Lookup<string, int> lookup;
lookup = (Lookup<string, int>)list.ToLookup(i => i.IP, i => i.Number);

但现在我需要通过值(数字)对此查找进行排序,并获得前10个键及其值.
这怎么可能?

我为什么要这个?
说master是最新的,发布是一年前的。修复了错误后,便针对发行版本创建了PR,现在也需要将此修复程序放到主站中,完美的选择,但是就我所知,这将需要一个新的分支。我只希望可以使用相同的原始修订分支合并到两者中(只要master仍然兼容)。

最好/最干净的方法是CSS将标题对齐#dates div到标题的右侧,并垂直居中。
我试过了float: right,但就是不允许vertical-align。我想避免使用浮动,所以我使用inline-block, 并使用相对定位。有没有更正确的做法呢?
我不喜欢这样的事实:我必须将顶部设置为 30 像素,并不断尝试直到它居中。
