Introuction To C# Lesson 0

Main introduction: C Sharp Programming/Foreword

Although C# is derived from the C programming language, it has features such as garbage collection that allow beginners to become proficient in C# more quickly than in C or C++. Similar to Java, it is objectoriented, comes with an extensive class library, and supports exception handling, multiple types of polymorphism, and separation of interfaces from implementations. Those features, combined with its powerful development tools, multiplatform support, and generics, make C# a good choice for many types of software development projects: rapid application development projects, projects implemented by individuals or large or small teams, Internet applications, and projects with strict reliability requirements. Testing

frameworks such as NUnit make C# amenable to test-driven development and thus a good language for use with Extreme Programming (XP). Its strong typing helps to prevent many programming errors that are common in weakly typed languages. Foreword A description of the C# language and introduction to this Wikibook. Getting started with C# A simple C# program and where to get tools to compile it. Language Basics Naming conventions Quickly describes the generally accepted naming conventions for C#. Basic syntax Describes the basics in how the applications you write will be interpreted. Variables The entities used to store data of various shapes.

Operators Summarizes the operators, such as the '+' in addition, available in C#. Data structures Enumerations, structs, and more. Control statements Loops, conditions, and more. How the program flow is controlled. Exceptions Responding to errors that can occur. Classes Namespaces Giving your code its own space to live in. Classes The blueprints of objects that describes how they should work. Objects Cornerstones of any object-oriented programming language, objects are the tools you use to perform work. Encapsulation and accessor levels

Explains protection of object states by encapsulation. The .NET Framework .NET Framework Overview An overview of the .NET class library used in C#. Console Programming Input and Output using the console. Windows Forms GUI Programming with Windows Forms. Advanced Object-Orientation Concepts Inheritance Re-using existing code to improve or specialise the functionality of an object. Interfaces Define a template, in which to base subclasses from. Delegates and Events Be informed about when an event happens and choose what method to call when it happens with delegates.

Abstract classes Build partially implemented classes. Partial classes Split a class over several files to allow multiple users to develop, but also to stop code generators interfering with source code. Collections Effectively manage (add, remove, find, iterate, etc.) large sets of data. Generics Allow commonly used collections and classes to appear to have specialisation for your custom class. Object Lifetime Learn about the lifetime of objects, where they are allocated and learn about garbage collection. Design Patterns Learn commonly used design methodologies to simplify and/or improve your development framework. Keywords
