string sData = "";
string sRegCityData = @"city_(?
System.Text.RegularExpressions.Regex reg = new System.Text.RegularExpressions.Regex(sRegCityData);
System.Text.RegularExpressions.MatchCollection match = reg.Matches(sData);
for (int I = 0; I < match.Count; I++)
{
//逐个导入到相应数组
//match[I].Groups["city"].Value的值选择数组
//match[I].Groups["no"].Value的值指示在数组中的索引
//match[I].Groups["data"].Value
}
先readline,在用split拆分一下
