为了获得遍历列表的枚举器,代码如下-
using System; using System.Collections.Generic; public class Demo { public static void Main(String[] args){ List<String> list1 = new List<String>(); list1.Add("One"); list1.Add("Two"); list1.Add("Three"); list1.Add("Four"); list1.Add("Five"); Console.WriteLine("Elements in List1..."); foreach (string res in list1){ Console.WriteLine(res); } List<String> list2 = new List<String>(); list2.Add("India"); list2.Add("US"); list2.Add("UK"); list2.Add("Canada"); list2.Add("Poland"); list2.Add("Netherlands"); Console.WriteLine("Elements in List2..."); List<String>.Enumerator demoEnum = list2.GetEnumerator(); while (demoEnum.MoveNext()) { string res = demoEnum.Current; Console.WriteLine(res); } Console.WriteLine("Is List2 equal to List1? = "+list2.Equals(list1)); } }
输出结果
这将产生以下输出-
Elements in List1... One Two Three Four Five Elements in List2... India US UK Canada Poland Netherlands Is List2 equal to List1? = False
让我们看另一个例子-
using System; using System.Collections.Generic; public class Demo { public static void Main(String[] args){ List<String> list = new List<String>(); list.Add("One"); list.Add("Two"); list.Add("Three"); list.Add("Four"); list.Add("Five"); list.Add("Six"); list.Add("Seven"); list.Add("Eight"); list.Add("Nine"); list.Add("Ten"); Console.WriteLine("Enumerator iterates through the list elements..."); List<String>.Enumerator demoEnum = list.GetEnumerator(); while (demoEnum.MoveNext()) { string res = demoEnum.Current; Console.WriteLine(res); } } }
输出结果
这将产生以下输出-
Enumerator iterates through the list elements... One Two Three Four Five Six Seven Eight Nine Ten
