我正在尝试在c#中创建一个“有序”的对象列表,其中该列表将按照ImdbId属性中值的最常出现次数进行排序。 我没有使用数据库,而是从远程API获取结果并需要以优雅的方式对列表进行排序。
class Movie
{
String ImdbId {get; set; }
String Name {get;set;}
... more properties
}
无序列表示例:
imdbId | Name
698649 | "Sex and the City" Models and Mortals
698669 | "Sex and the City" The Awful Truth
698649 | "Sex and the City" Models and Mortals
698649 | "Sex and the City" Models and Mortals
698679 | "Sex and the City" The Drought
698697 | "Sex and the City" Valley of the Twenty-Something Guys
1568911 | War Horse
而且排序后应该是这样的:
imdbId | Name
698649 | "Sex and the City" Models and Mortals
698649 | "Sex and the City" Models and Mortals
698649 | "Sex and the City" Models and Mortals
698669 | "Sex and the City" The Awful Truth
698679 | "Sex and the City" The Drought
698697 | "Sex and the City" Valley of the Twenty-Something Guys
1568911 | War Horse
这里是另一个例子:
imdbId | Name
1568911 | War Horse
698690 | "Sex and the City" The Turtle and the Hare
698653 | "Sex and the City" Old Dogs, New Dicks
698690 | "Sex and the City" The Turtle and the Hare
698690 | "Sex and the City" The Turtle and the aHare
1000774 | Sex and the City
而排序后应该像这样:
imdbId | Name
698690 | "Sex and the City" The Turtle and the Hare
698690 | "Sex and the City" The Turtle and the Hare
698690 | "Sex and the City" The Turtle and the aHare
698653 | "Sex and the City" Old Dogs, New Dicks
1000774 | Sex and the City
1568911 | War Horse
我尝试了以下内容,但没有成功。
List<Movie> newList = List
.OrderByDescending(a => a.ImdbId)
.ThenByDescending(a => a.ImdbId.Count())
.ToList();
有没有想过用Lambda或LINQ实现这个功能?
