design mode (C #)

Returns the design mode (C #) series Article index

Introduced

Define a series of algorithms that encapsulate them each, and make them interchangeable. This mode allows the algorithm to be changed independently from the customer using it.

Example

There is a message entity class that has an insert () and get () method for its operation, persistent data in a SQL Server database or in an XML file (two interchangeable algorithms). The client determines which algorithm to use.
