为了获得遍历字典的枚举数,代码如下-
using System; using System.Collections; using System.Collections.Generic; public class Demo { public static void Main(){ Dictionary<int, string> dict = new Dictionary<int, string>(); dict.Add(100, "Laptop"); dict.Add(150, "Desktop"); dict.Add(200, "Earphone"); dict.Add(300, "Tablet"); dict.Add(500, "Speakers"); dict.Add(750, "HardDisk"); dict.Add(1000, "SSD"); IDictionaryEnumerator demoEnum = dict.GetEnumerator(); Console.WriteLine("Enumerator iterating key-value pairs..."); while (demoEnum.MoveNext()) Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value); } }
输出结果
这将产生以下输出-
Enumerator iterating key-value pairs... Key = 100, Value = Laptop Key = 150, Value = Desktop Key = 200, Value = Earphone Key = 300, Value = Tablet Key = 500, Value = Speakers Key = 750, Value = HardDisk Key = 1000, Value = SSD
让我们看另一个例子-
using System; using System.Collections; using System.Collections.Generic; public class Demo { public static void Main(){ Dictionary<string, string> dict = new Dictionary<string, string>(); dict.Add("One", "Laptop"); dict.Add("Two", "Desktop"); dict.Add("Three", "Earphone"); dict.Add("Four", "Tablet"); dict.Add("Five", "Speakers"); dict.Add("Six", "HardDisk"); dict.Add("Seven", "SSD"); dict.Add("Eight", "Keyboard"); dict.Add("Nine", "Mouse"); IDictionaryEnumerator demoEnum = dict.GetEnumerator(); Console.WriteLine("Enumerator iterating key-value pairs..."); while (demoEnum.MoveNext()) Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value); } }
输出结果
这将产生以下输出-
Enumerator iterating key-value pairs... Key = One, Value = Laptop Key = Two, Value = Desktop Key = Three, Value = Earphone Key = Four, Value = Tablet Key = Five, Value = Speakers Key = Six, Value = HardDisk Key = Seven, Value = SSD Key = Eight, Value = Keyboard Key = Nine, Value = Mouse
