根据对象的属性对对象列表进行排序 [英] sorting a list of objects based on its properties

问题描述

如何对对象列表进行排序?
例如，

How would I sort a list of objects?
For example,

List<someobject> list = new List<someobject>();
list.add(someObject) 100 times

现在有

Now there is

someObject.someDoubleValue = .232;

每个someObject都有一个doubleDoubleValue属性，该属性包含一个双精度值.

现在，我想基于someObject.someDoubleValues对列表进行排序，以便该列表为

Each someObject has a someDoubleValue property which holds a double value.

Now, I want to sort the list based on someObject.someDoubleValues so the list would be

list[0] = someobject1.someDoubleValue =.2
list[1] = someObject2.someDoubleValue =.3
list[2] = someObject3.someDoubleValue = .4 

推荐答案

每个someObject是某个类的实例.实现 IComparable接口 [

Each someObject is an instance of some class. Implement the IComparable interface[^] for that class.

Without this, list.Sort() cannot know what order you want the list to be sorted in.

list.sort();

您将获得0.2,0.3,04

you will get 0.2,0.3,04
