排序C＃中的对象列表 [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，我试图找出一种有效的方法排序这个列表List CarList，包含6（或任何整数）Cars，由Car Make Date。我打算做泡泡排序，但会工作吗？任何帮助？

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

List< T> 类使得这一点变得轻而易举，因为它包含 排序方法。 （它使用QuickSort算法，而不是Bubble Sort，这通常更好）。更好的是，它有一个重载，它需要一个比较< T> 参数，

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.

请尝试以下操作：

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