ASP.NET Dictionary 的基本用法示例介绍

  

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) { }
