使用结构的示例程序

问题描述

限时删除！！

有人可以向我解释为什么输出为False，False而不是False，True吗?

Could someone explain to me why the output is False, False and not False, True?

感谢任何提示.

public class Program
    {
        static void Main(string[] args)
        {
            var user = new User() { Nom = "Clement" };
            Console.WriteLine("Avant: " + user.Panier.EstRegle);
            user.Panier.Regle();
            Console.WriteLine("Apres: " + user.Panier.EstRegle);
            Console.ReadKey();
        }


        public struct Panier
        {
            public bool EstRegle;
            public void Regle()
            {
                EstRegle = true;

            }
        }

        public class User
        {
            public string Nom { get; set; }
            public Panier Panier { get; set; }
            public User()
            {
                this.Panier = new TestConsole.Program.Panier();
            }
        }
    }

推荐答案

        public struct Panier
        {
            public bool EstRegle;
            public void Regle()
            {
                EstRegle = true;

            }
        }

因为结构的行为与C#中的类不同.

如果Panier是类而不是结构，那么您会看到
假"和"True".

Because structs behave differently than classes in C#.

If Panier were a class instead of a struct you would see
"False" and "True".
