如何在C#中将单词的字母拆分为数组? [英] How do I split a word's letters into an Array in C#?

问题描述

如何在C#中将字符串拆分为字符数组?

How do I split a string into an array of characters in C#?

示例字符串单词是"robot".

Example String word used is "robot".

程序应打印出:

r
o
b
o
t

原始代码段:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Diagnostics;
using System.IO;
using System.Text.RegularExpressions;


namespace Testing
{
class Program
{
    static void Main(string[] args)
    {
        String word = "robot";

        String[] token = word.Split(); // Something should be placed into the () to 
        //print letter by letter??

        foreach (String r in token)
        {
            Console.WriteLine(r);
        }
    }
}
}

如何正确执行代码?

推荐答案

为什么不呢?

public void WriteLetters(string s)
{
    foreach (char c in s)
    {
        Console.WriteLine(c); 
    }
}

如果您真的想在显式字符数组中查看它，请执行以下操作:

If you really want to see it in an explicit character array, do the following:

string s = "robot";
char[] charArray = s.ToCharArray();

如果随后要打印出来(每行1个)，请执行以下操作:

If you then want to print that out (1 per line), do the following:

for (int i = 0; i < charArray.Length; i++)
{
    Console.WriteLine(charArray[i]);
}

我不太确定您要做什么，所以我可能不太了解.

I'm not really sure what you're trying to do, so I may be way off base.

如果通过标记化，是指将字符存储在数组中，则已经将其存储在String对象中. ¹ .

If by tokenize, you mean store the characters in an array, you already have that in a String object¹.

_{¹ 并非如此，因为String使用索引器来遍历字符值，而在C/C ++中，字符串实际上是一个数组人物.出于我们的目的，我们可以将字符串视为字符数组}
