- What is a delegate?
- A delegate is a type-safe method reference. It can be used to execute any method with a matching signature.
- What is an event?
- An event is a field that is a delegate having the
eventkeyword applied. The keyword ensures that only+=and-=are used; this safely combines multiple delegates without replacing any existing event handlers.
- An event is a field that is a delegate having the
- How is a base class and a derived class related?
- A derived class (or subclass) is a class that inherits from a base class (or superclass).
- What is the difference between the
isandasoperators?- The
isoperator returnstrueif an object can be cast to the type. Theasoperator returns a reference if an object can be cast to the type; otherwise, it returnsnull.

- What's the difference between a destructor and a deconstructor?
- A destructor, also known as a finalizer, must be used to release resources owned by the object. A deconstructor is a new feature of C# 7 that allows a complex object to be broken down into smaller parts.
- What are the signatures of the constructors that all exceptions should have?
- The following are the signatures of the constructors that all exceptions should have:
- A constructor with no parameters
- A constructor with a
stringparameter usually namedmessage - A constructor with a
stringparameter, usually namedmessage, and anExceptionparameter usually namedinnerException
- The following are the signatures of the constructors that all exceptions should have:
- What is an extension method and how do you define one?
- An extension method is a compiler trick that makes a static method of a static class appear to be one of the members of a type. You define which type you want to extend by prefixing the type with
this.
