求正则匹配问题,从数据库连接字符串里获取用户名等
string constr = "data source=127.0.0.1;uid=sa;pwd=sa;database=pub;";
请问怎么从上面的字符串里抠出ip,用户,密码和数据库名?正则该怎么写?很迷糊

这个比我1楼的更好，直接通过Dictionary的键值获取对应值：

C# code

        string s = "data source=127.0.0.1;uid=sa;pwd=sa;database=pub;";        Dictionary<string, string> dictionary = s.Split(new char[] { ';' }, StringSplitOptions.RemoveEmptyEntries).ToDictionary(x => x.Split('=')[0], x => x.Split('=')[1]);        foreach (KeyValuePair<string, string> pair in dictionary)            Console.WriteLine(pair.Key + ":" + pair.Value);        Console.WriteLine("uid的值是：" + dictionary["uid"]);
