Triplet Class
Provides a basic utility class that is used to store three related objects.
Assembly: System.Web (in System.Web.dll)
The Triplet class is used as a basic structure to store three related objects. It is a utility class that is used in various ways throughout ASP.NET. You can use the Triplet class in your own code anywhere that you need a structure to contain three related objects and where data-hiding is not essential. The Triplet class does not encapsulate its object references, First, Second, and Third, in properties; it exposes them directly to all calling code as public class fields.
The following example uses a Triplet object to hold three integer values and another Triplet to hold three label controls.

When accessing reference types as members of a Triplet, only generic Object methods are available for that member. |
