What is the difference between early binding and late binding in C#?

Following are the access modifiers generally used for accessibility:

• Public: If you define an attribute or method as public, it can be accessed from any code of the project.
• Private: A private defined attribute or method can be accessed by any code within the containing class only.
• Protected: If you define the method or attribute as protected it can be accessed by any method in the inherited classes and any method within the same class.
• Internal: If you define an attribute or a method as internal, it is restricted to classes within the current position assembly.
• Protected internal: If you define an attribute or method as protected internal, access is restricted to classes within the current project assembly or types derived from the containing class.

Abstract class can have abstract and concrete methods whereas interface has only abstract methods.

The dispose() method is explicitly called by user to free unmanaged resources such as files, database connections etc whereas finalize() method is implicitly called by garbage collector to free unmanaged resources like files, database connections etc.

The dispose() method belongs to IDisposable interface whereas finalize() method belongs the Object class.

Method parameters must be different in method overloading whereas it must be same in method overriding.

Inheritance is not required in method overloading, it occurs within the same class. But inheritance is required in method overriding.

Object pool is a container of ready to use objects. It reduces the overhead of creating new object.

A delegate in C# is an object that holds the reference to a method. It is like function pointer in C++.

A Hashtable is a collection of key/value pairs. It contains values based on the key.

Reflection allows us to get metadata and assemblies of an object at runtime.

Garbage Collection is a process of releasing memory automatically occupied by objects which are no longer accessible.
