Check if the ArrayList has a fixed size in C#

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

Example

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main(String[] args) {
      ArrayList list1 = new ArrayList();
      list1.Add("One");
      list1.Add("Two");
      list1.Add("Three");
      list1.Add("Four");
      list1.Add("Five");
      Console.WriteLine("Elements in ArrayList...");
      foreach (string res in list1) {
         Console.WriteLine(res);
      }
      ArrayList list = ArrayList.Synchronized(list1);
      Console.WriteLine("Is ArrayList synchronized? = "+list.IsSynchronized);
      Console.WriteLine("Is ArrayList have a fixed size? = "+list.IsFixedSize);
   }
}

Output

This will produce the following output −

Elements in ArrayList...
One
Two
Three
Four
Five
Is ArrayList synchronized? = True
Is ArrayList have a fixed size? = False

Example

Let us see another example −

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main(String[] args) {
      ArrayList list1 = new ArrayList();
      list1.Add("ABC");
      list1.Add("BCD");
      list1.Add("CDE");
      list1.Add("DEF");
      list1.Add("EFG");
      list1.Add("GHI");
      list1.Add("HIJ");
      list1.Add("IJK");
      list1.Add("JKL");
      list1.Add("KLM");
      Console.WriteLine("Elements in ArrayList...");
      foreach (string res in list1) {
         Console.WriteLine(res);
      }
      ArrayList list = ArrayList.Synchronized(list1);
      Console.WriteLine("Is ArrayList synchronized? = "+list.IsSynchronized);
      ArrayList list2 = ArrayList.FixedSize(list1);
      Console.WriteLine("Is ArrayList have a fixed size? = "+list2.IsFixedSize);
   }
}

Output

This will produce the following output −

Elements in ArrayList...
ABC
BCD
CDE
DEF
EFG
GHI
HIJ
IJK
JKL
KLM
Is ArrayList synchronized? = True
Is ArrayList have a fixed size? = True
