C#检查HybridDictionary是否为只读
要检查HybridDictionary是否为只读，代码如下-
示例
using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
public static void Main() {
HybridDictionary dict1 = new HybridDictionary();
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("HybridDictionary1 elements...");
foreach(DictionaryEntry d in dict1) {
Console.WriteLine(d.Key + " " + d.Value);
}
Console.WriteLine("Is the HybridDictionary1 having fixed size? = "+dict1.IsFixedSize);
Console.WriteLine("If HybridDictionary1 read-only? = "+dict1.IsReadOnly);
Console.WriteLine("Is HybridDictionary1 synchronized = "+dict1.IsSynchronized);
HybridDictionary dict2 = new HybridDictionary();
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("\nHybridDictionary2 elements...");
foreach(DictionaryEntry d in dict2) {
Console.WriteLine(d.Key + " " + d.Value);
}
Console.WriteLine("Is HybridDictionary1 equal to HybridDictionary2? = "+(dict1.Equals(dict2)));
Console.WriteLine("Is the HybridDictionary2 having fixed size? = "+dict2.IsFixedSize);
Console.WriteLine("If HybridDictionary2 read-only? = "+dict2.IsReadOnly);
Console.WriteLine("Is HybridDictionary2 synchronized = "+dict2.IsSynchronized);
}
}输出结果
这将产生以下输出-
HybridDictionary1 elements... A Books B Electronics C Smart Wearables D Pet Supplies E Clothing F Footwear Is the HybridDictionary1 having fixed size? = False If HybridDictionary1 read-only? = False Is HybridDictionary1 synchronized = False HybridDictionary2 elements... 1 One 2 Two 3 Three 4 Four 5 Five 6 Six Is HybridDictionary1 equal to HybridDictionary2? = False Is the HybridDictionary2 having fixed size? = False If HybridDictionary2 read-only? = False Is HybridDictionary2 synchronized = False
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() {
HybridDictionary dict = new HybridDictionary();
dict.Add("1", "Finance");
dict.Add("2", "Marketing");
dict.Add("3", "IT");
dict.Add("4", "Operations");
dict.Add("5", "Purchase");
Console.WriteLine("HybridDictionary elements...");
foreach(DictionaryEntry d in dict) {
Console.WriteLine(d.Key + " " + d.Value);
}
Console.WriteLine("Is the HybridDictionary having fixed size? = "+dict.IsFixedSize);
Console.WriteLine("If HybridDictionary read-only? = "+dict.IsReadOnly);
Console.WriteLine("Is HybridDictionary synchronized = "+dict.IsSynchronized);
}
}输出结果
这将产生以下输出-
HybridDictionary elements... 1 Finance 2 Marketing 3 IT 4 Operations 5 Purchase Is the HybridDictionary having fixed size? = False If HybridDictionary read-only? = False Is HybridDictionary synchronized = False
