检查两个List对象在C#中是否相等
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
示例
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> 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 List3 equals to List2? = True
