Anonymous Delegates Sample 

Download sample

This sample demonstrates using an anonymous delegate to calculate a salary bonus for an employee. Using an anonymous delegate simplifies the program because there is no need to define a separate method.

The data for each employee is stored in an object containing personal details as well as a delegate that references the algorithm required to calculate the bonus. By defining the algorithm by means of a delegate, the same method can be used to perform the bonus calculation, irrespective 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.
