This module provides students with the theory and syntax for creating and
destroying objects in a C# application.
After completing this module, students will be able to:
Create objects by using the new operator.
Use constructors to initialize objects.
Create overloaded constructors that can accept varying parameters.
Describe the lifetime of an object and what happens when it is destroyed.
Inherit from IDisposable interface and implement Dispose method.
Introduction, Creating and Destroying Objects, Methods Common to All Objects, Classes and Interfaces,... are the main contents of the book "Effective Java Second Edition", invite you to refer to additional documentation service needs learning and research. Hope this is useful references for you.
This tutorial uses a unique system that allows you to learn
the concepts presented in this lesson without struggling
with the frustration of coding errors caused by mistakes in
typing or formatting.
As the picture (right) shows, the sources are organized
logically in several folder
The Life and Times of an Object First, let's recap what happens when you create and destroy an object. You create an object like this: TextBox message = new TextBox(); // TextBox is a reference type From your point of view

In this chapter, you will learn how to programmatically create (and destroy) a directory system as well as move data into and out of various streams (file based, string based, memory based, etc.). The latter part of this chapter examines the role of isolated storage, which allows you to persist per-user data into a safe sandbox, regardless of the security settings of a target machine.

are f lawed. If the objective of the firm is to maximize investors’ wealth, the alternative rules sometimes fail to identify projects that further this end and in fact sometimes lead to acceptance of projects that destroy wealth. We will examine the payback period rule, the discounted payback rule, and the internal rate of return rule.
The Payback Period
The payback period rule stipulates that cash f lows must completely repay the initial outlay prior to some cutoff payback period.
Introducing the Microsoft .NET Platform
in use, these objects will always have a reference count greater than zero, so unless they are implicitly deconstructed, their memory may never be recovered. For a C or C++ programmer—accustomed to ensuring that objects are properly destroyed, essentially managing memory on their own—this sounds perfectly normal, and a good reason for not trusting anyone else to take care of managing resources. However, in the .NET environment, Microsoft is striving to make developing software easier. Later in this chapter, we cover a how .
