具有相同模式的字符串，使用正则表达式组的提取和替换的案例

对具有相同模式的字符串内不同的组的提取怎样做呢,我是这样做的：

提取字符串：sourcetext:{name:john,data:[1,2,3],name:marry,data:[4,5,6]}

代码：

Regex reg = new Regex(@"data:[([w|.|,]{1,})]",RegexOptions.IgnoreCase);
MatchCollection matches = reg.Matches(series);
foreach (Match match in matches)
{

   GroupCollection groups = match.Groups;
   for (int j = 0; j < groups.Count; j++)
   {
     string weightjsonInKgMode = covertToKg(groups[j].Value.Replace("data:[","").Replace("]",""));
     string regModel = groups[j].Value;
     regModel = regModel.Replace("[","[").Replace("]","]");
     series = Regex.Replace(series,regModel,weightjsonInKgMode);
   }
}

结果：

series中的“1,3”，和“4,6”，将分别被weightjsonInKgMode字符串“0.001,0.002,0.003”和“0.004,0.0045,0.0046”所代替
