New is a type of procedure called a constructor that is used to initialize new objects before any other code in an object executes. A New constructor can be used to open files, connect to databases, initialize variables, and take care of any other tasks that need to be done before an object can be used....

Classes are symbolic representations of objects; classes describe the properties, fields, methods, and events that form objects in the same way that blueprints describe the items that form buildings. Just as a blueprint can be used to create multiple buildings, a single class can be used to create as many objects as necessary. Just as a blueprint defines which parts of a building are accessible to people who use the building, so too can classes control user access to object items through encapsu...

The gist of the new method is this: you must create your own custom class that implements the IComparable interface and overrides ...
