Anonymous Delegates Sample

  • Article

This sample demonstrates how to use an anonymous method to calculate a salary bonus for an employee. An anonymous method simplifies the program because you do not have to define a separate method.

Note

This sample is misnamed. The correct term for this feature is anonymous methods. Furthermore, anonymous methods are a feature of C# 2.0 and have been mostly superseded in C# 3.0 by lambda expressions. For more information about anonymous methods and lambda expressions, see Anonymous Functions (C# Programming Guide).

The data for each employee is stored in an object that contains personal details and a delegate that references the algorithm required to calculate the bonus. By using a delegate to define the algorithm, the same method can be used to perform the bonus calculation, regardless of how it is actually calculated. Also of note, a local variable, multiplier, becomes a captured outer variable because it is referenced in a delegated calculation.
