Boxing : Boxing is the process of converting a value type to the type object or to any interface type implemented by this value type. Refer MSDN
Boxing will take Variable from Stack (Value types) and store it into Heap (Object type)
Boxing is implicit. There is no need to type cast the value type to Object Type.
Example: String mystr = "Welcome to C# boxing"; Object myObj = mystr; // Implicit conversion of String to Object
Unboxing: It's the reverse of boxing. It needs to be done explicitly by user.
Example: String mystr = "Welcome to C# boxing"; Object myObj = mystr; // Implicit conversion of String to Object String mystr2 = (String) myObj; // Explicit conversion from Object to String
