How to store different types of arrays in C#

There are two ways to store the different types of arrays in C#.

1. Object type is a base type for all the types in .net
   
   Example
   
   

   using System.Collections;

   namespace article

   {

   class programme

   {

   static void main()

   {

   object[] a = new object[3];

   a[0] = 101; //interger

   a[1] = c#; //string

    

   foreach( object obj in a)

   {

   console.writeline(obj); 

   }

   }

   }

   }

   
   
2. Another method is to use the "array list class that present in System.collection namespace".
   
   

   ArrayList array = new arraylist();

   array.add(1);

   array.add(abc);
