去除重复字符串,效率

 private string Method1(string text)
    {
        string t = text;
       // t = Regex.Replace(t, @"(.)\1+", "$1");
       
        while (Regex.IsMatch(t, @"(.+|.)([^\1]*?)(\1)"))//(.)([^\1]+?)(\1)
        {
            t = Regex.Replace(t, @"(.+|.)([^\1]*?)(\1)", "$1$2");
        }
         return t;
       
    }
    private string Method2(string text)
    {
        string t =text;
        //t = Regex.Replace(t, @"(.)\1+", "$1");
        int i = 0;
        while (Regex.IsMatch(t, @"(.)([^\1]*?)(\1)"))
        {
            i++;
            t = Regex.Replace(t, @"(.)([^\1]*?)(\1)", "$1$2");
        }
       // atb2.Text = Regex.Replace(t, @"(.)\1+", "$1");
       
            Response.Write(i);return t;
    }

希望大家帮忙看看，有更好的方法请写出来
