HybridDictionary ছোট হলে ListDictionary, বড় হলে Hashtable ব্যবহার করে। এটি ডিফল্টভাবে থ্রেড-সেফ নয়; lock(dict.SyncRoot) দিয়ে সিঙ্ক্রোনাইজ করা যায়।
উদাহরণ ১: HybridDictionary সিঙ্ক্রোনাইজ করা
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);
}
}
}
}

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
উদাহরণ ২: ছোট HybridDictionary সিঙ্ক্রোনাইজ করা
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);
}
}
}
}
আউটপুট
HybridDictionary elements... A SUV B MUV C AUV Synchronize access... A SUV B MUV C AUV
সারসংক্ষেপ
SyncRootপ্রপার্টি লকে জন্য অবজেক্ট প্রদান করে।lock(dict.SyncRoot)ব্লকের ভিতরে সমস্ত অপারেশন থ্রেড-সেফ হয়।IsSynchronizedপ্রপার্টি সবসময়falseরিটার্ন করে (নন-সিঙ্ক্রোনাইজড)।
