一:通过Key访问Value的方法:
//判断App.config配置文件中是否有Key(非null) if (ConfigurationManager.AppSettings.HasKeys()) { //获取“theDate”键的Value foreach (string s in ConfigurationManager.AppSettings.GetValues("theDate")) { Console.WriteLine(s); } }二 获取所有K ey的Value集合
//判断App.config配置文件中是否有Key(非null) if (ConfigurationManager.AppSettings.HasKeys()) { List<string> theKeys = new List<string>(); //保存Key的集合 List<string> theValues = new List<string>(); //保存Value的集合 //遍历出所有的Key并添加进theKeys集合 foreach (string theKey in ConfigurationManager.AppSettings.Keys) { theKeys.Add(theKey); } //根据Key遍历出所有的Value并添加进theValues集合 for (int i = 0; i < theKeys.Count; i++) { foreach (string theValue in ConfigurationManager.AppSettings.GetValues(theKeys[i])) { theValues.Add(theValue); } } //验证一下 Console.WriteLine("*************Key*************"); foreach (string s in theKeys) { Console.WriteLine(s); } Console.WriteLine("************Value************"); foreach (var item in theValues) { Console.WriteLine(item); } }
