我如何通过每个对象的成员对对象列表进行排序？(How can I sort a list of objects by a member of each object? [duplicate])

我如何通过每个对象的成员对对象列表进行排序？(How can I sort a list of objects by a member of each object? [duplicate])

这个问题在这里已经有了答案：

如何按对象中的属性排序列表<T> 19答案 class candle { public DateTime date { get; set; } public double open { get; set; } public double high { get; set; } public double low { get; set; } public double close { get; set; } } List<candle> candleList = new List<candle>();

假设我已经为candeList添加了许多蜡烛，那么我如何按日期对candleList进行排序呢？

另外，我如何从candleList中删除所有重复的条目？

谢谢

This question already has an answer here:

How to Sort a List<T> by a property in the object 19 answers class candle { public DateTime date { get; set; } public double open { get; set; } public double high { get; set; } public double low { get; set; } public double close { get; set; } } List<candle> candleList = new List<candle>();

Assuming I have added many candles to candeList, How can I then sort candleList by date?

Also, how can I remove all duplicate entries from candleList?

Thank you

漂亮的标准，简单的linq。

var candleList = candleList.Distinct().OrderBy(x => x.date).ToList();

正如Adam在下面提到的，这只会删除列表中的重复实例，而不是具有所有相同属性值的实例。

您可以实现自己的IEqualityComparer<Candle>作为通过它的选项。 的IEqualityComparer

你可能想看看msdn，并阅读Linq和Enumerable方法： MSDN - 枚举方法

Pretty standard, simple linq.

var candleList = candleList.Distinct().OrderBy(x => x.date).ToList();

As Adam mentioned below, this will only remove duplicate instances within the list, not instances which all of the same property values.

You can implement your own IEqualityComparer<Candle> as an option to get passed this. IEqualityComparer
