design mode (C #)

Returns the design mode (C #) series Article index

Introduced

Defines the skeleton of an algorithm in an operation, and delays some steps into subclasses. Template method enables subclasses to redefine certain steps of the algorithm without altering the structure of an algorithm.

Example

There is a message entity class that operates with a get () method, and the ValidateUser () method is used to check the current user's permissions before each fetch (), and the data may be in the SQL Server database or in an XML file. (Here first check the user's permissions, then get the data is the skeleton of the algorithm, get the data delay to implement in subclasses)
