How to code for Delegate
In this artical explains basic understanding for delegate and how to create nad
This code for .net framework for C#
This artical is usefull for .net(C#) developers who requires basic understanding
for delegate concept
Using the code
Delegate is a class that can hold a reference to a method or a function. Delegate
class has a signature and it can only reference those methods whose signature is
compliant with the class. Delegates are type-safe functions pointers or callbacks
Below is the code for delegates
delegate int CalculateArea();
delegate int CalculateAreaParam(<span
As above code we have created two delegate CalculateArea and CalculateAreaParam.One
is without any parameter and other one is with paramter.
In this code In this method CallDelegate, we have created object for CalculateArea.
This object is initated by Calculate . Once we invoke this object it will calculate
method. Here we have created anther delegate CalculateAreaParam which is with parameter
so while invoking this method we need to pass relavant parameter so it will call
appropriate iniated methods.
