ASP.NET Dictionary 的基本用法

        Dictionary<int, string> dic = new Dictionary<int, string>();
        //添加元素
        dic.Add(1, "小棠");
        dic.Add(2, "小吴");
        //判断某个key是否存在
        if (!dic.ContainsKey(2))
        {
            dic.Add(2, "小吴");
        }
 
        //移除某个
        dic.Remove(3);
 
        //获取某个的值
        string a = dic[2];
 
        //遍历数据
        foreach (KeyValuePair<int, string> kvp in dic)
        {
            Response.Write(kvp.Key + "," + kvp.Value);
        }
 
        //遍历key
        foreach (int s in dic.Keys)
        {
 
        }
 
        //遍历value
        foreach (string s in dic.Values)
        {
 
        }
