Check if Hashtable has a fixed size in C#

To check if Hashtable has a fixed size, the code is as follows −

Example

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main(){
      Hashtable hash = new Hashtable(10);
      hash.Add("1", "A");
      hash.Add("2", "B");
      hash.Add("3", "C");
      hash.Add("4", "D");
      hash.Add("5","E");
      hash.Add("6", "F");
      hash.Add("7", "G");
      hash.Add("8","H");
      hash.Add("9", "I");
      hash.Add("10", "J");
      Console.WriteLine("Is the Hashtable having fixed size? = "+hash.IsFixedSize);
   }
}

Output

This will produce the following output −

Is the Hashtable having fixed size? = False

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", "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);
   }
}

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
