Summary

Provides support for value types. This class is the base class for all value types.

Description

[Note: Data types are separated into value types and reference types. Value types are either stack-allocated or allocated inline in a structure. Reference types are heap-allocated. Both reference and value types are derived from the ultimate base class Object. In cases where a value type needs to act like an object, a wrapper that makes the value type look like a reference object is allocated on the heap, and the value type's value is copied into it. The wrapper is marked so that the system knows that it contains a value type. This process is known as boxing, and the reverse process is known as unboxing. Boxing and unboxing allow any type to be treated as an object.

]

Example

In the following example, the number 3 is boxed as a Int32, and System.Int32.ToString () is called.

using System;
class Boxer {
  public static void Main() {
   Console.WriteLine("Value is {0}.", 3.ToString());
  }
}
The output is

Value is 3.
