Boxing and Unboxing both are used for type conversions.
The process of converting from a value type to a reference type is called boxing. Boxing is an implicit conversion. Here is an example of boxing in C#.
// Boxing
int anum = 123;
Object obj = anum;
Console.WriteLine(anum);
Console.WriteLine(obj); ​
The process of converting from a reference type to a value type is called unboxing. Here is an example of unboxing in C#.
// Unboxing
Object obj2 = 123;
int anum2 = (int)obj;
Console.WriteLine(anum2);
Console.WriteLine(obj);
