Creating a synchronized wrapper for the Hashtable in C#
To create a synchronized wrapper for the Hashtable, the code is as follows −
Example
using System;
using System.Collections;
public class Demo {
public static void Main() {
Hashtable hash = new Hashtable();
hash.Add("1", "AB");
hash.Add("2", "CD");
hash.Add("3", "EF");
hash.Add("4", "GH");
hash.Add("5", "IJ");
hash.Add("6", "KL");
Console.WriteLine("Hashtable elements...");
foreach(DictionaryEntry d in hash) {
Console.WriteLine("Key = "+d.Key + ", Value = " + d.Value);
}
Console.WriteLine("Hashtable is synchronized? = "+hash.IsSynchronized);
}
}Output
This will produce the following output −
Hashtable elements... Key = 1, Value = AB Key = 2, Value = CD Key = 3, Value = EF Key = 4, Value = GH Key = 5, Value = IJ Key = 6, Value = KL Hashtable is synchronized? = False
Example
Let us see another example −
using System;
using System.Collections;
public class Demo {
public static void Main() {
Hashtable hash = new Hashtable();
hash.Add("1", "Mark");
hash.Add("2", "Gary");
hash.Add("3", "Jacob");
hash.Add("4", "Andy");
hash.Add("5", "Jack");
Console.WriteLine("Hashtable elements...");
foreach(DictionaryEntry d in hash) {
Console.WriteLine("Key = "+d.Key + ", Value = " + d.Value);
}
Console.WriteLine("Hashtable is synchronized? = "+hash.IsSynchronized);
Hashtable hash2 = Hashtable.Synchronized(hash);
Console.WriteLine("Hashtable is synchronized? = "+hash2.IsSynchronized);
}
}Output
This will produce the following output −
Hashtable elements... Key = 1, Value = Mark Key = 2, Value = Gary Key = 3, Value = Jacob Key = 4, Value = Andy Key = 5, Value = Jack Hashtable is synchronized? = False Hashtable is synchronized? = True
