If given the following delegate declaration: public delegate void MyCallback(object obj); write code segments to perform the following: A) , Design a non-static method that can be contained within an instance/object of the MyCallback delegate type. This method should display values of two data fields contained within the object that is passed to the method. Make-up your own method definition that meets these requirements. B) ( ) Creat an instance of the MyCallback delegate (i.e. a delegate object) and initialize this object to contain an entry point of the method defined in part A) as well as a copy of the object that calls this method. Include the declaration statement of the object needed to create the required delegate instance. C) ( :) Writ a statement that uses the delegate object created in part B) to call the method contained within this delegate object and include error checking.

If given the following delegate declaration: public delegate void MyCallback(object obj); write code segments to perform the following: A) -, Design a non-static method that can be contained within an instance/object of the MyCallback delegate type. This method should display values of two data fields contained within the object that is passed to the method. Make-up your own method definition that meets these requirements. B) ( ) Creat an instance of the MyCallback delegate (i.e. a delegate object) and initialize this object to contain an entry point of the method defined in part A) as well as a copy of the object that calls this method.

Question 2. A;. Use the MyCallback delegate type from question 2) to creat an event field and the corresponding event property. Make up your own event identifiers. . B) ( n) Writ a complete statement that will add the method that you created in question 3 A) to be a handler of the event you created in this question. Make up your own object name that raises the event.
