用LINQ对类列表进行排序 [英] Sorting a List of Class with LINQ

问题描述

我有一个List<MyClass>，我想按MyClass的DateTime CreateDate属性对其进行排序.

I have a List<MyClass> and I want to sort it by DateTime CreateDate attribute of MyClass.

使用LINQ可以吗?

谢谢

推荐答案

您可以按排序顺序枚举它:

You can enumerate it in sorted order:

IEnumerable<MyClass> result = list.OrderBy(element => element.CreateDate);

您还可以使用ToList()转换为新列表并重新分配给原始变量:

You can also use ToList() to convert to a new list and reassign to the original variable:

list = list.OrderBy(element => element.CreateDate).ToList();

这与对原始列表进行排序并不完全相同，因为如果仍然有人引用旧列表，他们将看不到新的排序.如果您实际上想对原始列表进行排序，则需要使用List<T>.Sort方法.

This isn't quite the same as sorting the original list because if anyone still has a reference to the old list they won't see the new ordering. If you actually want to sort the original list then you need to use the List<T>.Sort method.
