c# - 正则表达式拆分字符串并将括号 [ ] 中的内容放入数组

Question

我正在尝试使用正则表达式将字符串拆分为 2 个数组，结果如下。

String str1 = "First Second [insideFirst] Third Forth [insideSecond] Fifth";

如何将 str1 拆分为 2 个如下所示的数组:

ary1 = ['First Second','Third Forth','Fifth'];
ary2 = ['insideFirst','insideSecond'];

Answer 1

这是我的解决方案

string str = "First Second [insideFirst] Third Forth [insideSecond] Fifth";
MatchCollection matches = Regex.Matches(str,@"\[.*?\]");
string[] arr = matches.Cast<Match>()
                      .Select(m => m.Groups[0].Value.Trim(new char[]{'[',']'}))
                      .ToArray();
foreach (string s in arr)
{
    Console.WriteLine(s);
}

string[] arr1 = Regex.Split(str,@"\[.*?\]")
                     .Select(x => x.Trim())
                     .ToArray();
foreach (string s in arr1)
{
    Console.WriteLine(s);
}

输出

insideFirst
insideSecond
First Second
Third Forth
Fifth
