Reference Type

6:07 AM - By azeheruddin khan 0

Reference Type: - The values assigned to variables of reference type are stored in heap memory instead of stack.  And a reference type variable points to an address of a data value but not to the data value.

  1. Object: - It is a general purpose data type, all pre-defined and user-defined data types inherit from System.Object class.
  2. String: - It represents a string of Unicode characters and allows easy manipulation and assignment of strings.

Example program for reference type

using System;
namespace DataType
{
    class Program
    {
        static void Main(string[] args)
        {            
            String b = "Fresher2";
            b += "programmer";
            Console.WriteLine("website name is " + b);
            object a = 10;
            Console.WriteLine("the type of a is:" + a.GetType());
            Console.ReadLine();
        }
    }
}


Note: - In the above given program, GetType() is a method of System namespace used to get the type of a given variable or object.

Output: - website name is Fresher2programmer
the type of a is: System.Int32
