Question
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.
