Check if Hashtable is synchronized C#

CsharpServer Side ProgrammingProgramming

To check if Hashtable is synchronized, the code is as follows −

Example

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main() {
      Hashtable hash = new Hashtable();
      hash.Add("One", "Katie");
      hash.Add("Two", "John");
      hash.Add("Three", "Barry");
      hash.Add("Four", "");
      hash.Add("Five","Harry");
      hash.Add("Six", "F");
      hash.Add("Seven", "Tom");
      hash.Add("Eight","Andy");
      hash.Add("Nine", "I");
      hash.Add("Ten", "Tim");
      Console.WriteLine("Hashtable Key and Value pairs...");
      foreach(DictionaryEntry entry in hash) {
         Console.WriteLine("{0} and {1} ", entry.Key, entry.Value);
      }
      Console.WriteLine("Is the Hashtable having fixed size? = "+hash.IsFixedSize);
      Console.WriteLine("If Hashtable read-only? = "+hash.IsReadOnly);
      Hashtable hash2 = Hashtable.Synchronized(hash);
      Console.WriteLine("Is Hash synchronized = "+hash2.IsSynchronized);
   }
}

Output

This will produce the following output −

Hashtable Key and Value pairs...
One and Katie
Ten and Tim
Five and Harry
Three and Barry
Seven and Tom
Two and John
Four and  
Eight and Andy
Nine and I
Six and F
Is the Hashtable having fixed size? = False
If Hashtable read-only? = False
Is Hash synchronized = True

Example

Let us see another example −

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main() {
      Hashtable hash = new Hashtable();
      hash.Add("One", 1);
      hash.Add("Two", 2);
      hash.Add("Three", 2);
      hash.Add("Four", 4);
      hash.Add("Five",5);
      hash.Add("Six", 6);
      hash.Add("Seven", 7);
      Console.WriteLine("Hashtable Key and Value pairs...");
      foreach(DictionaryEntry entry in hash) {
         Console.WriteLine("{0} and {1} ", entry.Key, entry.Value);
      }
      Console.WriteLine("Is the Hashtable having fixed size? = "+hash.IsFixedSize);
      Console.WriteLine("If Hashtable read-only? = "+hash.IsReadOnly);
      Console.WriteLine("Is Hash synchronized = "+hash.IsSynchronized);
   }
}

Output

This will produce the following output −

Hashtable Key and Value pairs...
One and 1
Five and 5
Three and 2
Seven and 7
Two and 2
Four and 4
Six and 6
Is the Hashtable having fixed size? = False
If Hashtable read-only? = False
Is Hash synchronized = False
