见过不少人、经过不少事、也吃过不少苦，感悟世事无常、人心多变，靠着回忆将往事串珠成链，聊聊感情、谈谈发展，我慢慢写、你一点一点看......
1、使用 List<T>.Sort 方法与自定义比较器
public class Person{
public string Name { get; set; } public int Age { get; set; }}public class PersonComparer : IComparer<Person>{
public int Compare(Person x, Person y) {
// 按年龄升序排序 return x.Age.CompareTo(y.Age); // 或更复杂的排序逻辑 }}class Program{
static void Main() {
List<Person> people = new List<Person> {
new Person { Name = "A", Age = 15 }, new Person { Name = "B", Age = 25 }, new Person { Name = "C", Age = 35 } }; people.Sort(new PersonComparer()); foreach (var person in people) {
Console.WriteLine($"{person.Name}, {person.Age}"); } }}2、使用 LINQ 的 OrderBy 方法与自定义键选择器
var people = new List<Person> {
new Person { Name = "Alice", Age = 30 }, new Person { Name = "Bob", Age = 25 }, new Person { Name = "Charlie", Age = 35 } };
var sortedPeople = people.OrderBy(p => p.Age).ToList();
//var sortedPeople = people.OrderBy(p => p.Age).ThenBy(p => p.Name).ToList(); foreach (var person in sortedPeople) {
Console.WriteLine($"{person.Name}, {person.Age}"); }3、默认的排序顺序
public class Person : IComparable<Person>{
public string Name { get; set; } public int Age { get; set; } public int CompareTo(Person other) {
if (other == null) return 1; return this.Age.CompareTo(other.Age); }}
// 然后可以直接使用 Sort 方法，不需要传递比较器people.Sort();关注我，不失联。有啥问题请留言。
