ASP.NET Dictionary 的基本用法示例介绍

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) { }
