要检查HybridDictionary是否为只读,代码如下-
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
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
