考考你的编程艺术能力【雅】 一点～

引用自 CSDN某帖子  考考你的编程艺术能力，谁能将这段代码改的 【雅】 一点～

本人感觉70楼 avon520 解法很不错

    protected void Page_Load(object sender, EventArgs e)
    {
        List<string> lst = new List<string> { "Apple", "MS", "Google" };
        string s = joinList(lst, ";");
    }

    private string joinList(List<string> lst, string separator)
    {
        if (lst == null)
            throw new Exception("can not be null");

        if (lst.Count == 0)
            return "";

        return string.Join(separator, lst.ToArray());

    }

另附 以下解法：

        public string JoinList1(string[] StringList)
        {
            StringBuilder sb = new StringBuilder();
            foreach (string StrArg in StringList)
            {
                sb.Append(StrArg);
                sb.Append(";");
            }
            return sb.ToString().TrimEnd(';');
        }

        public string JoinList2(List<string> StringList)
        {
            StringBuilder lzsb = new StringBuilder();
            foreach (string StrArg in StringList)
            {
                lzsb.Append(StrArg);
                lzsb.Append(";");
            }
            return lzsb.ToString().TrimEnd(';');
        }

在这里引用:

string[] strlist = new string[] { "Apple", "MS", "Google"};
            string str1 = JoinList1(strlist);
            Response.Write(str1);

            Response.Write("\r\n");

            List<string> lst = new List<string> { "Apple", "MS", "Google" };
            string str2 = JoinList2(lst);
            Response.Write(str2);
