排序对象在C＃列表 [英] Sorting a List of objects in C#

问题描述

public class CarSpecs
{
  public String CarName { get; set; }

  public String CarMaker { get; set; }

  public DateTime CreationDate { get; set; }
}

这是一个列表，我试图找出一条有效途径这个排序列表列表卡洛斯，含6（或任意整数金额）汽车，由汽车制造日期。我打算做冒泡排序，而是将这项工作？任何帮助吗？

This is a list and I am trying to figure out an efficient way to sort this list List CarList, containing 6(or any integer amount) Cars, by the Car Make Date. I was going to do Bubble sort, but will that work? Any Help?

感谢

推荐答案

的列表< T> 类，这个平凡的你，因为它包含一个 排序方法。 （它使用快速排序算法，不冒泡排序，通常是更好的反正。）更妙的是，它具有过载，需要一个比较< T> 的说法，这意味着你，可以通过lambda表达式，使事情确实很简单

The List<T> class makes this trivial for you, since it contains a Sort method. (It uses the QuickSort algorithm, not Bubble Sort, which is typically better anyway.) Even better, it has an overload that takes a Comparison<T> argument, which means you can pass a lambda expression and make things very simple indeed.

试试这个：

CarList.Sort((x, y) => DateTime.Compare(x.CreationDate, y.CreationDate));
