2 个解决方案

#1

var result = new Regex(@"\d+").Matches(s)
                              .Cast<Match>()
                              .Select(m => Int32.Parse(m.Value))
                              .ToArray();

#2

Use a foreach loop like this:

使用这样的foreach循环：

string result = "";

foreach (string str in s)
{
    int number;
    if (int.TryParse(str, out number))
       result += s;
    else
       result += ",";
}
