数组中最频繁的数字

LINQ起来。我知道这在VB中，但是您应该可以将其转换为C＃：

Dim i = From Numbers In ints _ Group Numbers By Numbers Into Group _ Aggregate feq In Group Into Count() _ Select New With {.Number = Numbers, .Count = Count}

编辑：现在也用C＃：

var i = from numbers in M     group numbers by numbers into grouped     select new { Number = grouped.Key, Freq = grouped.Count()};
