Boxing short

<source lang="csharp">using System; using System.Collections; class MainClass {

 static void Main(string[] args)
 {    
   
   short s = 25;
   Console.WriteLine("short s = {0}", s);
   Console.WriteLine("short is a: {0}", s.GetType().ToString());
 }

}</source>

short s = 25
short is a: System.Int16

Box the value type into a reference type

<source lang="csharp">using System; using System.Collections; class MainClass {

 static void Main(string[] args)
 {    
   short s = 25;
   
   object objShort = s;
   Console.WriteLine("Boxed object is a: {0}", objShort.GetType().ToString());
 }

}</source>

Boxed object is a: System.Int16

unbox the reference back into a short

<source lang="csharp">using System; using System.Collections; class MainClass {

 static void Main(string[] args)
 {    
   short s = 25;
   
   object objShort = s;
   
   short anotherShort = (short)objShort;
   Console.WriteLine("short anotherShort = {0}", anotherShort);
   Console.WriteLine("Unboxed object is a: {0}", anotherShort.GetType().ToString());
 }

}</source>

short anotherShort = 25
Unboxed object is a: System.Int16
