C#:如何将对象列表转换为该对象的单个属性列表? [英] C#: How to convert a list of objects to a list of a single property of that object?

问题描述

说我有:

IList<Person> people = new List<Person>();

person 对象具有 FirstName、LastName 和 Gender 等属性.

And the person object has properties like FirstName, LastName, and Gender.

如何将其转换为 Person 对象的属性列表.例如，到一个名字列表.

How can I convert this to a list of properties of the Person object. For example, to a list of first names.

IList<string> firstNames = ???

推荐答案

List<string> firstNames = people.Select(person => person.FirstName).ToList();

并带有排序

List<string> orderedNames = people.Select(person => person.FirstName).OrderBy(name => name).ToList();
