var mystr = "產(chǎn)品有不同的型號，型號比如有ab1,ab2,b1,b2,b3，等等.現(xiàn)在假設(shè)有a1,a2,a3,a4";
var matches = Regex.Matches(mystr, @"([a-z]+)\d+\s*[,，]\s*(\1(\d+)(?:\s*[,，]\s*)*)*");
foreach (Match match in matches)
{
if (string.IsNullOrEmpty(match.Groups[3].Value))
{
continue;
}
var str = match.Value;
var chart = match.Groups[1].Value;
var count = Convert.ToInt32(match.Groups[3].Value);
if (count>1)
{
mystr = mystr.Replace(str, chart + "1~" + chart + count+",");
}
}
Console.WriteLine(mystr);
