OrderedDictionary의 읽기 전용 복사본을 얻으려면 코드는 다음과 같습니다 -
예
using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
public static void Main(){
OrderedDictionary dict1 = new OrderedDictionary();
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("OrderedDictionary1 elements...");
foreach(DictionaryEntry d in dict1){
Console.WriteLine(d.Key + " " + d.Value);
}
OrderedDictionary dict2 = new OrderedDictionary();
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("\nOrderedDictionary2 elements...");
foreach(DictionaryEntry d in dict2){
Console.WriteLine(d.Key + " " + d.Value);
}
Console.WriteLine("\nIs OrderedDictionary1 equal to OrderedDictionary2? = "+(dict1.Equals(dict2)));
OrderedDictionary orderedDict = dict2.AsReadOnly();
Console.WriteLine("Is OrderedDictionary read-only? = "+orderedDict.IsReadOnly);
}
} 출력
이것은 다음과 같은 출력을 생성합니다 -
OrderedDictionary1 elements... A Books B Electronics C Smart Wearables D Pet Supplies E Clothing F Footwear OrderedDictionary2 elements... 1 One 2 Two 3 Three 4 Four 5 Five 6 Six Is OrderedDictionary1 equal to OrderedDictionary2? = False Is OrderedDictionary read-only? = True
예
다른 예를 보겠습니다 -
using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
public static void Main(){
OrderedDictionary dict = new OrderedDictionary();
dict.Add("A", "Books");
dict.Add("B", "Electronics");
dict.Add("C", "Smart Wearables");
dict.Add("D", "Pet Supplies");
dict.Add("E", "Clothing");
dict.Add("F", "Footwear");
Console.WriteLine("OrderedDictionary elements...");
foreach(DictionaryEntry d in dict){
Console.WriteLine(d.Key + " " + d.Value);
}
OrderedDictionary orderedDict = dict.AsReadOnly();
Console.WriteLine("Is OrderedDictionary read-only? = "+orderedDict.IsReadOnly);
}
} 출력
이것은 다음과 같은 출력을 생성합니다 -
OrderedDictionary elements... A Books B Electronics C Smart Wearables D Pet Supplies E Clothing F Footwear Is OrderedDictionary read-only? = True
