代码如下:
Dictionaryo_Dic = new Dictionary (); //添加元素 o_Dic.Add("01", "aaa"); o_Dic.Add("02","bbb"); //判断某个key是否存在 if (!o_Dic.ContainsKey("03")) { o_Dic.Add("03", "ccc"); } //移除某个 o_Dic.Remove("03"); //取某个的值 string a = o_Dic["02"]; //遍歷 foreach (KeyValuePair kvp in o_Dic) { Response.Write(kvp.Key + "," + kvp.Value); } //遍歷key foreach (string s in o_Dic.Keys) { } //遍歷value foreach (string s in o_Dic.Values) { }
