ARRAYS in C-Sharp

When defining variables you can choose between scalar number and arrays. Arrays in C# are declared by adding a set of square brackets to the end of the variable declaration. All members of an array must be of the same type. You cannot have different types in an array.

Binary Serialization in C#

In a previous tutorial we talked about serialization and the various option for formatting its data output. In this document we will talk about binary serialization. Binary serialization is used for communication between .Net applications and is not a human-readable format. Windows relies on serialization for many important tasks such as remoting and copying items to the clipboard.

Collections in C#

Sometimes is necessary to hold more than one object in your program as an object, a part, of a bigger collection. For example, one might want to store information about each book in his possession. So, a collection which represents these books must be defined. The C# language and the .Net environment offer you numerous techniques for implementing these kinds of collections in your code. One of those techniques is by using a collection structure.

Exception Handling in C#

Every self-respected programmer should include exception handling techniques. Sometimes your application will generate an error. Regardless of who was responsible for this error, the programmer or the user, it is up to the first to include the necessary exception handling techniques to keep his/her program from crashing. The .Net environment provides useful techniques for avoiding disastrous errors such as try-catch statements and user-defined exceptions.

Graphics with C#

The .Net provides classes for the programmer to be able to work with graphics. This technology is called GDI+ and controls custom drawing on the screen. These classes instruct the graphics device driver to send the appropriate output on the screen. This tutorial is an introduction to the GDI+ technology in order to start drawing simple objects on screen.

Regular Expressions in C#

A regular expression’s use is for finding substrings in a large string expression. It supports the use of various wild cards and other very useful techniques for performing the required actions. The namespace System.Text.RegularExpressions contains a number of classes associated with regular expressions.

Sequential Lists: The Queue and Stack Class

Sequential lists are collection of objects that can be entered or extracted in a sequential way. They don’t provide access to objects in the middle on the list. You can only access a specific object each time you extract it. The two classes named “Queue” and ”Stack” which belong to the “System.Collections” namespace provide you with this kind of functionality, each of them in a slightly different way. The Queue class offers you access to the first object on the list, whereas the Stack class offers you access to the last object on the list. By first and last we mean the first and last object that entered the list. So, the Queue class is a First-in, First-out collection(FIFO Collection) whereas the Stack class is a Last-in, First-out(LIFO Collection). In this tutorial you will create and use both classes to see how they behave when entering and extracting data. You will usually work with such collections with temporary and disposable data. For a more permanent use, arrays provide much better functionality.

Serialization in C#

Many applications need to communicate with other applications to exchange data or store data in the hard disk. The .Net framework has made these tasks quite simple by including the serialization technique, which can convert objects into binary, SOAP(Simple Object Access Protocol ) or XML documents in order to provide a convenient way for storing and transferring information. Besides the three mentioned format types you can also implement custom serialization to take complete control of the serialization output.

Threading with C#

Multi-core processors are new standards on the user’s hardware. By taking advantage of the multi-processing capabilities of these machines you can achieve significant performance upgrade with some minor changes in your code. When an application does not make use of threading techniques it is wasting valuable resources. This tutorial will cover the basic threading concepts and threading methods and properties.

Create Windows in C#

A C# program can be written either in a text editor or in an integrated development environment (IDE). The later provides access to various other features. In this tutorial we examine the Visual Studio 2008 IDE in order to illustrate various concepts of a C# windows program.

XML Serialization in C#

Serialization is the process of persisting an object to disk. Another application can deserialize your object and it will be in the same state it was before the serialization. This tutorial talks about XML serialization. The namespace containing classes and methods suitable for such a serialization is System.Xml.Serialization.

Sending Emails in C#

The process of sending emails is a simple one. However, because of its dependence on many factors things can become complicated. For example, if the server is not responding, the user should be able to choose whether to stop or not.

Introduction to Open GL in C#

OpenGl is an API similar to direct3D. However, OpenGL (Open Graphics Library) is not supported by Microsoft and is a cross-language, cross-platform API used for writing applications that produce 2d or 3D graphics. Over 300 functions are implemented in this API which can help you draw complex 3D scenes from primitive data such as polygons and triangles. Mesa 3D is an open source library API which is also compatible with the OpenGl protocol. OpenGl aims at two key goals: 1. To present to the programmer a uniform API that hides the complexities of interfacing with different 3D accelerators. 2. To hide the different capabilities of hardware platforms. OpenGL converts primitives into pixels that are depicted on your screen. Primitives can be polygons, triangles or lines. The transformation is accomplished by a graphics pipeline.

Direct3D with C#

Direct 3D is an API used for displaying applications with rich multimedia content. You can add 2D/3D graphics, video and sound in your application. You can also create 3D engines for video games. Direct Graphics is the portion of API that deals with the graphics of a direct 3D application. It is oriented towards 3D design but it also works well for 2D graphics. In order to use sound you have to use the functions of Direct Sound.

Data Encryption in C#

Data is most vulnerable when transferred across a network or stored on a disk drive. An attacker with some knowledge and skills can bypass security software and gain access to sensitive data. However, you can use cryptography to your advantage. You can protect your private data by encrypting their information with a key code, only you will know.

Creating Emails in C#

E-mail is an extremely popular communication mechanism. The .Net framework has added the System.Net.Mail namespace which provides classes that enable you to easily create and transmit email messages. Messages can include plain text and attachments. In this tutorial we will talk about creating emails.

Authenticating Users in C#

Unauthorized access of sensitive data must be prohibited in a business application. Unauthorized users must not be able to view other people’s information. In a windows program, sometimes it is necessary to provide different information in guests and users. A guest should not be able to see important data of the program’s flow. The authentication methods require the System.Security.Principal namespace.

While Loops in C#

C# provides several mechanisms for flow control in a program. The loops in C# allow you to execute a block of code repeatedly, until a certain condition is met. This condition can be the number of repetition, a variable taking a specified value or something completely different. The while loop is a pre-test loop and is used to execute a block of code for a number of times not known before the loop begins. The do..while loop is a post-test loop and is used for the same purposes as the while loop.

The SWITCH Statement in C#

The switch statement offers the programmer the capability to choose a specific block of code from a set of mutually exclusive ones. It is similar but not identical to the if statement. The block of code that will be chosen is not known before the execution of the program. This can be for example due to different windows platform or specific localization settings of each country.
