C# 反转字符串中的所有数字？

Question

我有一个字符串:

“你好7866592这是我的12432字符串和823我需要翻转所有123 ”

我想成为

“你好2956687这是我的23421字符串和328我需要翻转所有321 ”

我使用这个正则表达式来获取所有数字:

Regex nums = new Regex("\d+");

var replacedString = 
    Regex.Replace(//finds all matches and replaces them
    myString, //string we're working with
    @"\d+", //the regular expression to match to do a replace
    m => new string(m.Value.Reverse().ToArray())); //a Lambda expression which
        //is cast to the MatchEvaluator delegate, so once the match is found, it  
        //is replaced with the output of this method.
