将字符串拆分为单个字符的字符串数组

Question

我想车削简单的东西"this is a test"进入

new string[] {"t","h","i","s"," ","i","s"," ","a"," ","t","e","s","t"}

我真的必须这样做吗？

test = "this is a test".Select(x => x.ToString()).ToArray();

编辑:为了澄清,我不想要一个char数组,理想情况下我想要一个字符串数组.我没有看到上述代码有任何问题,只是因为我认为有一种更简单的方法.

Answer 1

我相信这就是你要找的东西:

char[] characters = "this is a test".ToCharArray();

Answer 2

C#中的字符串已经有一个char索引器

string test = "this is a test";
Console.WriteLine(test[0]);

和...

if(test[0] == 't')
  Console.WriteLine("The first letter is 't'");

这也有效......

Console.WriteLine("this is a test"[0]);

还有这个...

foreach (char c in "this is a test")
  Console.WriteLine(c);

编辑:

我注意到关于char []数组的问题已经更新了.如果你必须有一个string []数组,这里是你如何在c#中的每个字符处拆分一个字符串:

string[] test = Regex.Split("this is a test", string.Empty);

foreach (string s in test)
{
  Console.WriteLine(s);
}

Answer 3

Simple!!
one line:

 var res = test.Select(x => new string(x, 1)).ToArray();

Answer 4

您可以只使用String.ToCharArray()，然后将每个字符视为代码中的字符串。

这是一个例子：

    foreach (char c in s.ToCharArray())
        Debug.Log("one character ... " +c);

Answer 5

尝试这个：

var charArray = "this is a test".ToCharArray().Select(c=>c.ToString());
