C＃换行每n个字符 [英] C# line break every n characters

问题描述

假设我有一个带有文本的字符串：THIS IS A TEST。我如何分割每n个字符？因此，如果n为10，则它将显示：

Suppose I have a string with the text: "THIS IS A TEST". How would I split it every n characters? So if n was 10, then it would display:

"THIS IS A "
"TEST"

..你的想法。原因是因为我想把一条很大的线分割成更小的线，像字包绕。我想我可以使用string.Split（）为此，但我不知道如何，我很困惑。

..you get the idea. The reason is because I want to split a very big line into smaller lines, sort of like word wrap. I think I can use string.Split() for this, but I have no idea how and I'm confused.

任何帮助将不胜感激。

推荐答案

让我们从我的答案代码审查。每个 字符插入一个换行符：

Let's borrow an implementation from my answer on code review. This inserts a line break every n characters:

public static string SpliceText(string text, int lineLength) {
  return Regex.Replace(text, "(.{" + lineLength + "})", "$1" + Environment.NewLine);
}

编辑：

要返回一个字符串数组：

To return an array of strings instead:

public static string[] SpliceText(string text, int lineLength) {
  return Regex.Matches(text, ".{1," + lineLength + "}").Cast<Match>().Select(m => m.Value).ToArray();
}
