Object-Oriented Programming in C# (OBJ201)

This thorough and comprehensive Object-Oriented Programming in C# training class provides a practical introduction to programming in C#, utilizing the services provided by .NET. This course emphasizes the C# language.

This course is intended to be fully accessible to programmers who do not already have a strong background in object-oriented programming in C-like languages, such as C++ or Java. It is ideal, for example, for procedural programmers who desire to learn C#.

An important thrust of the course is to teach C# programming from an object-oriented perspective. It is often difficult for programmers trained originally in a procedural language to start "thinking in objects." This course introduces object-oriented concepts early, and C# is developed in a way that leverages its object orientation. A case study is used to illustrate creating a complete system using C# and .NET. Besides supporting traditional object-oriented features, such as classes, inheritance, and polymorphism, C# introduces several additional features, such as properties, indexers, delegates, events, and interfaces that make C# a compelling language for developing object-oriented and component-based systems. This course provides thorough coverage of all these features.

C# as a language is elegant and powerful. But to utilize its capabilities fully, you need to have a good understanding of how it works with the .NET Framework. The course explores several important interactions between C# and the .NET Framework, and it includes an introduction to major classes for collections, delegates, and events. It includes a succinct introduction to creating GUI programs using Windows Forms.
