public static Dictionary<String, String> gameslist = new Dictionary<string, String>();

加内容
admins.gameslist= new System.Collections.Generic.Dictionary<string,string>();

        admins.gameslist.Add("测试服务器", "0");
        admins.gameslist.Add("过关斩将", "201");
        admins.gameslist.Add("桃园结义", "301");
        admins.gameslist.Add("单刀赴会", "302");
        admins.gameslist.Add("飞龙在天", "202");
        admins.gameslist.Add("义薄云天", "101");
        admins.gameslist.Add("决胜千里", "102");

读取

foreach (var item in admins.gameslist.Values)

        {
            Response.Write(item);


        }
