在 C# 中检查两个 List 对象是否相等
要检查两个 List 对象是否相等,代码如下 -
示例
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..."); foreach (string res in list2){ Console.WriteLine(res); } Console.WriteLine("Is List2 equal to List1? = "+list2.Equals(list1)); } }
输出
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
示例
让我们看另一个示例 -
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..."); foreach (string res in list2){ Console.WriteLine(res); } List<string> list3 = new List<string>(); list3 = list2; Console.WriteLine("Is List3 equals to List2? = "+list3.Equals(list2)); } }
输出
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 List3 equals to List2? = True
