c#对象在当前上下文中不存在

Question

免责声明:我是 C# 新手。我很可能做错了什么，但我不知道要尝试Google等什么，所以我希望有人能告诉我我做错了什么.

无论如何，我在 createPlayer 方法中使用我的构造函数创建了一个播放器对象，我可以打印创建的对象的值，但是之后我不能再打印它了，它说:

player1 doesn't exist in the current context.

我该怎么办？

主文件

using System;

namespace project
{
    class Program
    {
        static void Main(string[] args)
        {
                createPlayer();

            Console.WriteLine(player1.Name); //Doesn't exist in current context
            Console.ReadKey();
        }
        static public void createPlayer()
        {
            Console.WriteLine("\nType in your name :");
            Player player1 = new Player(Console.ReadLine()); 
            Console.WriteLine("\n Name: " + player1.Name + "\n Speed: " + player1.Speed + "\n Defence: " + player1.Defence + "\n Damage: " + player1.Damage);
            Console.WriteLine("\nPress 1 to continue, Press 2 to reroll.");
        }
    }
}

构造函数

 using System;

using System.Collections.Generic;
using System.Text;

namespace projekti
{
    public class Player
    {
        public string Name;
        public int Speed;
        public int Damage;
        public int Defence;
        public int Health;
        public Player(string nm)
        {
            Name = nm;
            Random r = new Random();
            Speed = r.Next(1, 26);
            Damage = r.Next(1, 26);
            Defence = r.Next(1, 26);
            Health = 100;
        }
    }
}

player1 在 createPlayer() 中实例化，因此在该函数的本地范围内。如果你想让其他函数访问它，你可以让 createPlayer() 返回 player1。

static void Main(string[] args)
{
    var player1 = createPlayer();

    Console.WriteLine(player1.Name);
    Console.ReadKey();
}
static public Player createPlayer()
{
    Console.WriteLine("\nType in your name :");
    Player player1 = new Player(Console.ReadLine()); 
    Console.WriteLine("\n Name: " + player1.Name + "\n Speed: " + player1.Speed + "\n Defence: " + player1.Defence + "\n Damage: " + player1.Damage);
    Console.WriteLine("\nPress 1 to continue, Press 2 to reroll.");

    return player1;
}
