我有一个字符串:

我只想保留 "key : "" - " 之间的字符串.我怎样才能做到这一点?我必须使用正则表达式还是可以用其他方式来做?

I want to just keep the string which is between "key : " and " - ". How can I do that? Must I use a Regex or can I do it in another way?

推荐答案

也许,一个好方法就是剪掉一个子串:

Perhaps, a good way is just to cut out a substring:

String St = "super exemple of string key : text I want to keep - end of my string";

int pFrom = St.IndexOf("key : ") + "key : ".Length;
int pTo = St.LastIndexOf(" - ");

String result = St.Substring(pFrom, pTo - pFrom);
