如何在C#中获得对HybridDictionary的同步访问？
要获得对HybridDictionary的同步访问，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("\nSynchronize access...");
lock(dict2.SyncRoot) {
foreach(DictionaryEntry d in dict2) {
Console.WriteLine(d.Key + " " + d.Value);
}
}
}
}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 Synchronize access... 1 One 2 Two 3 Three 4 Four 5 Five 6 Six
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("A", "SUV");
dict.Add("B", "MUV");
dict.Add("C", "AUV");
Console.WriteLine("HybridDictionary elements...");
foreach(DictionaryEntry d in dict) {
Console.WriteLine(d.Key + " " + d.Value);
}
Console.WriteLine("\nSynchronize access...");
lock(dict.SyncRoot) {
foreach(DictionaryEntry d in dict) {
Console.WriteLine(d.Key + " " + d.Value);
}
}
}
}输出结果
这将产生以下输出-
HybridDictionary elements... A SUV B MUV C AUV Synchronize access... A SUV B MUV C AUV
