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.
