复制代码 代码如下:

Dictionary<string, string> o_Dic = new Dictionary<string, string>();

//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<string, string> 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) { }
