私人的IEnumerable<串GT; GetSubStrings（字符串输入，字符串的开始，结束串）
 {
正则表达式R =新的正则表达式（Regex.Escape（开始）+（*）？+ Regex.Escape（结束））; 
 MatchCollection匹配= r.Matches（输入）; 
的foreach（赛的比赛在比赛中）
收益率的回报match.Groups [1] .value的; 
} 
 

I need to get all substrings from string.
For ex:

StringParser.GetSubstrings("[start]aaaaaa[end] wwwww [start]cccccc[end]", "[start]", "[end]");

that returns 2 string "aaaaaa" and "cccccc" Suppose we have only one level of nesting. Not sure about regexp, but I think it will be userful.

private IEnumerable<string> GetSubStrings(string input, string start, string end)
{
    Regex r = new Regex(Regex.Escape(start) + "(.*?)" + Regex.Escape(end));
    MatchCollection matches = r.Matches(input);
    foreach (Match match in matches)
        yield return match.Groups[1].Value;
}
