Question

To encapsulate more than one method into a single delegate which operator is used

Answer 1

A delegate in C# is similar to a function pointer in C or C++. Using a delegate allows the programmer to encapsulate a reference to a method inside a delegate. The delegate object can then be passed to code which can call the referenced method, without having to know at compile time which method will be invoked.
