Hello  Helixpoint，

Hello Helixpoint,

有一种方法可以使用正则表达式来解析字符串。

There is a way to parse string by using regex.

 String s = "dgdfjfirirr.12348658634.3434dasdasdsad12344231";
            MatchCollection vMatches = Regex.Matches(s, "[0-9]+(\\.?[0-9]+)?");
            foreach (Match m in vMatches) {
                var a = m.Value;
            }    

祝你好运，
