Question

我在显示对象的属性以及在类之间传输它们时遇到麻烦。我也无法从set方法获取错误消息。看来我可以输入任何东西而不会出错。我知道问题可能存在于对象中，因为尝试显示它时，我只是获得了空白的变量名。

    namespace Project
{
    class Program
    {
        static void Main(string[] args)
        {
            string name;
            double strength = 0;
            double dexterity = 0;
            double hitPoints = 0;
            double armor = 0;

            Console.WriteLine("--WELCOME TO THE BATTLE--\n");

                Console.WriteLine("Please enter the statistics for warrior one.");
                Console.WriteLine("Name: ");
                name = Console.ReadLine();
                Console.WriteLine("Strength: ");
                strength = Convert.ToDouble(Console.ReadLine());
                Console.WriteLine("Dexterity: ");
                dexterity = Convert.ToDouble(Console.ReadLine());
                Console.WriteLine("Hit Points: ");
                hitPoints = Convert.ToDouble(Console.ReadLine());
                Console.WriteLine("Armor: ");
                armor = Convert.ToDouble(Console.ReadLine());
                Warrior warriorOne = new Warrior(name, strength, dexterity, hitPoints, armor);

                Console.WriteLine("\nPlease enter the statistics for warrior two.");
                Console.WriteLine("Name: ");
                name = Console.ReadLine();
                Console.WriteLine("Strength: ");
                strength = Convert.ToDouble(Console.ReadLine());
                Console.WriteLine("Dexterity: ");
                dexterity = Convert.ToDouble(Console.ReadLine());

                armor = Convert.ToDouble(Console.ReadLine());
                Warrior warriorTwo = new Warrior(name, strength, dexterity, hitPoints, armor);

            Console.WriteLine("\nWarriors:\n" + warriorOne.Name + "--" + "Strength " + warriorOne.Strength + ", Dexterity " + warriorOne.Dexterity + ", HitPoints " + warriorOne.HitPoints + ", Armor " + warriorOne.Armor);

在构造器中尝试设置Warrior属性的Name类是一个问题。你有这个（我只包括相关的位）：

public Warrior(string name)
{
    name = Name;
}

public string Name { get; set; }

请注意，您不在此处设置Name属性。您正在将参数name设置为Name属性的任何一个（可能是null）。

要解决此问题，只需切换作业的顺序即可：

public Warrior(string name)
{
    Name = name;
}

您可能还需要检查所有其他属性（这似乎是一个常见错误，您要在{{ 1}}，而不是 left ）。

请记住，您几乎应该始终分配给公共访问者（大写的访问者），以便您的=代码运行。尝试除修改属性set方法之外的私有后备字段。

C＃在其他类中使用对象并显示它们* REVISED
