C# 在IEnumerable中选择其他非关键字段

我有一节课

 public class AmenityShowtime
    {
        public String AmenityKey { get; set; }
        public String AmenityIcon { get; set; }
        public String shTimes { get; set; }
    }

最后，我希望有一个由以下嵌套类组成的结构：

 public class AmenityShowtime
        {
            public String AmenityKey { get; set; }
            public String AmenityIcon { get; set; }
            public String shTimes { get; set; }
        }
    // Movie Class 
    public class theMovie
    {
        public String Movie_title { get; set; }
        public String Rating { get; set; }
        public String RunTime { get; set; }
        public List<theAmenities> amens { get; set; }
    }

    public class theAmenities
    {
        public String AmenityName { get; set; }
        public String AmenityIcon { get; set; }
        public List<theTimes> times { get; set; }
    }

    public class theTimes
    {
        public String timepref { get; set; }
    }

我一定错过了什么，提前谢谢你如果你想在分组中加入修正案，那么一种方法是：

var query = amShow.GroupBy(ams => new {ams.AmenityKey, ams.AmenityIcon}, 
                           ams => ams.shTimes);

请注意，现在确实需要

var

关键字，因为这是一个

i分组

（这将基于键和图标进行分组，如果键相同，我假设图标相同，因此这与仅按键分组基本相同）

现在你可以做了

foreach (var grp in query)
{
     theAmenities thisMovieAmenities = new theAmenities();
     thisMovieAmenities.AmenityName = grp.Key.AmenityKey;
     thisMovieAmenities.AmenityIcon = grp.Key.AmenityIcon;
     ...

---

如果要避免匿名类型，还可以在分组中创建类成员：

IEnumerable<IGrouping<theAmenities,string>> query = amShow.GroupBy(
     ams => new theAmenities(){AmenityKey = ams.AmenityKey, AmenityIcon = ams.AmenityIcon}, 
     ams => ams.shTimes);

IEnumerable query=amShow.GroupBy(
ams=>newtheamanies（）{amenditykey=ams.amenditykey，amendityicon=ams.amendityicon}，
ams=>ams.shTimes）；

但这需要类TheAmanies实现

IEquatable

接口，以允许GroupBy运算符将具有相同键的所有TheAmanies对象识别为相等。 如果改用匿名类型，这将自动工作。但这种方法的优点是，如果确实可能有多个项目具有相同的键但图标不同，您可以让您的iQuatable忽略修正图标

var query = amShow.GroupBy(ams => new {ams.AmenityKey, ams.AmenityIcon}, 
                           ams => ams.shTimes);

foreach (var grp in query)
{
     theAmenities thisMovieAmenities = new theAmenities();
     thisMovieAmenities.AmenityName = grp.Key.AmenityKey;
     thisMovieAmenities.AmenityIcon = grp.Key.AmenityIcon;
     ...

IEnumerable<IGrouping<theAmenities,string>> query = amShow.GroupBy(
     ams => new theAmenities(){AmenityKey = ams.AmenityKey, AmenityIcon = ams.AmenityIcon}, 
     ams => ams.shTimes);
