检查两个ListDictionary对象在C#中是否相等
要检查两个ListDictionary对象是否相等,代码如下-
示例
using System;using System.Collections;
using System.Collections.Specialized;
public class Demo {
public static void Main(){
ListDictionary dict1 = new ListDictionary();
dict1.Add("A", "Books");
dict1.Add("B", "Electronics");
dict1.Add("C", "Smart Wearables");
dict1.Add("D", "Pet Supplies");
dict1.Add("E", "Clothing");
dict1.Add("F", "Footwear");
Console.WriteLine("ListDictionary1 elements...");
foreach(DictionaryEntry d in dict1){
Console.WriteLine(d.Key + " " + d.Value);
}
ListDictionary dict2 = new ListDictionary();
dict2.Add("1", "One");
dict2.Add("2", "Two");
dict2.Add("3", "Three");
dict2.Add("4", "Four");
dict2.Add("5", "Five");
dict2.Add("6", "Six");
Console.WriteLine("\nListDictionary2 elements...");
foreach(DictionaryEntry d in dict2){
Console.WriteLine(d.Key + " " + d.Value);
}
ListDictionary dict3 = new ListDictionary();
dict3 = dict2;
Console.WriteLine("\nIs ListDictionary3 equal to ListDictionary2? = "+(dict3.Equals(dict2)));
}
}
输出结果
这将产生以下输出-
ListDictionary1 elements...A Books
B Electronics
C Smart Wearables
D Pet Supplies
E Clothing
F Footwear
ListDictionary2 elements...
1 One
2 Two
3 Three
4 Four
5 Five
6 Six
Is ListDictionary3 equal to ListDictionary2? = True
示例
让我们看另一个例子-
using System;using System.Collections;
using System.Collections.Specialized;
public class Demo {
public static void Main(){
ListDictionary dict1 = new ListDictionary();
dict1.Add("A", "Books");
dict1.Add("B", "Electronics");
dict1.Add("C", "Smart Wearables");
dict1.Add("D", "Pet Supplies");
dict1.Add("E", "Clothing");
dict1.Add("F", "Footwear");
Console.WriteLine("ListDictionary1 elements...");
foreach(DictionaryEntry d in dict1){
Console.WriteLine(d.Key + " " + d.Value);
}
ListDictionary dict2 = new ListDictionary();
dict2.Add("1", "One");
dict2.Add("2", "Two");
dict2.Add("3", "Three");
dict2.Add("4", "Four");
dict2.Add("5", "Five");
dict2.Add("6", "Six");
Console.WriteLine("\nListDictionary2 elements...");
foreach(DictionaryEntry d in dict2){
Console.WriteLine(d.Key + " " + d.Value);
}
Console.WriteLine("\nIs ListDictionary1 equal to ListDictionary2? = "+(dict1.Equals(dict2)));
}
}
输出结果
这将产生以下输出-
ListDictionary1 elements...A Books
B Electronics
C Smart Wearables
D Pet Supplies
E Clothing
F Footwear
ListDictionary2 elements...
1 One
2 Two
3 Three
4 Four
5 Five
6 Six
Is ListDictionary1 equal to ListDictionary2? = False
