Question

我想拆分以下内容：

name[]address[I]dob[]nationality[]occupation[]

所以我的结果是：

name[]
address[I]
dob[]
nationality[]
occupation[]

我尝试使用Regex.Split但无法获得这些结果。

Answer 1

使用此正则表达式模式：

\w*\[\w*\]

Answer 2

正则表达式应该没问题。您还可以考虑使用string.IndexOf捕获开始和结束方括号，例如：

IEnumerable<string> Results(string input)
{
    int currentIndex = -1;
    while (true)
    {
        currentIndex++;
        int openingBracketIndex = input.IndexOf("[", currentIndex);
        int closingBracketIndex = input.IndexOf("]", currentIndex);

        if (openingBracketIndex == -1 || closingBracketIndex == -1)
            yield break;

        yield return input.Substring(currentIndex, closingBracketIndex - currentIndex + 1);
        currentIndex = closingBracketIndex;     
    }
}

Answer 3

string inputString = "name[]address[I]dob[]nationality[]occupation[]";    
var result = Regex.Matches(inputString, @".*?\[I?\]").Cast<Match>().Select(m => m.Groups[0].Value).ToArray();
