一个字符串转换为字符数组 [英] Converting a string to a char array

问题描述

让我们说我有这样的字符串。

Let's say I have a string like this.

Dim str As String = "code"

我需要向下突破该字符串的字符数组这样，

I need to break this string down to an array of characters like this,

{"c", "o", "d", "e"}

我怎样才能做到这一点？

How can I do this?

推荐答案

每一个字符串是一个隐含的字符数组。所以，你可以取得第三个字符：

Every string is an implicit char-array. So you can get the 3rd char by:

Dim char3 = str(2)

修改：只是为了完整性的缘故。您也可以使用 String.ToCharArray 字符串实例转换到一个新的字符数组实例。采用的核心利益 ToCharArray 是您收到的字符数组是可变的，这意味着你可以真正改变每个个性。

Edit: Just for the sake of completeness. You can also use String.ToCharArray to convert the string instance to a new char-array instance. The core benefit of using ToCharArray is that the char-array you receive is mutable, meaning you can actually change each individual character.

请注意，您也可以使用 LINQ 。比如你想要一个字符串的前三个字母：

Note that you could also use LINQ. If you for example want the first three characters of a String:

Dim firstThree As Char() = str.Take(3).ToArray()
