Array.ToString() 返回 System.Char[] c# [英] Array.ToString() returning System.Char[] c#

问题描述

我正在做一个刽子手游戏，在游戏开始时，玩家必须猜测的单词被打印为星星.在尝试编写一次之后，我刚刚开始再次制作它，并且只有我无法修复的凌乱代码.所以我决定最好再写一遍.唯一的问题是，当我尝试使用 array.ToString() 打印出我的数组时；它只返回 System.char[].见下文.

Im making a hangman game, at the start of the game the word that the player must guess is printed as stars. I have just started making it again after attempting to write it once and just having messy code that i couldn't bug fix. So I decided it best to write it again. The only problem is, when i try to get my array to print out by using array.ToString(); it just returns System.char[]. See below.

代码:

class Program
{
    static void Main(string[] args)
    {
        string PlayerOneWord;
        string PlayerTwoGuess;
        int lives = 5;

        Console.WriteLine("Welcome to hangman!\n PLayer one, Please enter the word which player Two needs to guess!");
        PlayerOneWord = Console.ReadLine().ToLower();

        var stars = new char[PlayerOneWord.Length];
        for (int i = 0; i < stars.Length ; i++)
        {
                stars[i] = '*';
        }

        string StarString = stars.ToString();

        Console.Write("Word to Guess: {0}" , StarString);

        Console.ReadLine();
    }
}

输出:

输出应该是 Word to guess: Hello.

请有人解释为什么会发生这种情况，因为这不是我第一次遇到这个问题.

Please will someone explain why this is happening as its not the first time I have run into this problem.

推荐答案

在简单数组上调用 ToString 只会返回 "T[]" 而不管类型是什么 >T 是.它对 char[] 没有任何特殊处理.

Calling ToString on a simple array only returns "T[]" regardless what the type T is. It doesn't have any special handling for char[].

要将 char[] 转换为 string，您可以使用:

To convert a char[] to string you can use:

string s = new string(charArray);

但是对于您的具体问题，有一个更简单的解决方案:

But for your concrete problem there is an even simpler solution:

string stars = new string('*', PlayerOneWord.Length);

构造函数 public String(char c, int count) 重复 c count 次.
