ASP.NET 泛型類型 Dictionary操作

protected void Page_Load(object sender, EventArgs e){//泛型Dictionary  Dictionary<string, string> dit = new Dictionary<string, string>();dit.Add("13", "張三");dit.Add("22", "李四");Response.Write("總數" + dit.Count + "<br/>");//字典數據總數  dit.Remove("13");//刪除一個鍵  if (!dit.ContainsKey("13")){dit.Add("13", "張三1");}//判讀如果不包含指定的鍵則添加  foreach (KeyValuePair<string, string> kvp in dit){Response.Write(kvp.Key);Response.Write("=====" + kvp.Value);Response.Write("<br/>");}//循環字典中數據  
Dictionary<string, string>.KeyCollection ditkey = dit.Keys;foreach (string k in ditkey){Response.Write(k + "<br/>");}//循環字典數據的鍵  
Dictionary<string, string>.ValueCollection ditvalue = dit.Values;foreach (var v in ditvalue){Response.Write(v + "<br/>");}//循環字典數據里的值  foreach (var ditk in dit.Keys){Response.Write(ditk + "<br/>");}//另一種獲取字典鍵的方法  string f = dit["13"];Response.Write(f);//根據鍵 獲取值  string s = string.Empty;if (dit.TryGetValue("13", out s)){Response.Write("<br/>找到");}else{Response.Write("<br/>未找到");}//查找鍵是否存在  //泛型List 類型  List<string> a = new List<string>();a.Add("aa");a.Add("bb");foreach (string b in a){Response.Write("<br/>" + b + "<br/>");}//泛型IList  IList<string> Il = new List<string>();Il.Add("11");Il.Add("22");foreach (var i in Il){Response.Write(i + "<br/>");}}
