Multicast delegate contains reference to more than one method or it could be a combination of other delegates, which is also known as delegate chaining.

As you know, multiple class inheritance is not possible in C#. But you can achieve this goal using interfaces because multiple interface inheritance is allowed in C#. We can learn this thing better with an example. Create 2 interfaces IA and IB. IA contains a method PrintA() and IB contains a method PrintB(). Create 3
I hope you have already came across questions such as why C# doesn’t support multiple inheritance, why multiple inheritance is not supported in C# etc. One of the main reason behind this is Diamond Shape Problem. You can learn better about this problem with an example. Suppose you have 4 classes named as A, B, C,
