C# (pronounced "C Sharp") is a language used to create computer applications that tell the machine what to do and when. In the various lessons on this web site, we study the C# language by creating console applications, which are text-based programs that display their results in a black or gray window.

The lessons on this site use step-by-step instructions with a patient detail-oriented approach, accentuated by various useful examples in every section. To make it easy to learn effectively, the lessons are organized in topics so you can lead to the particular part you are interested in.

If you are a beginner, we recommend you follow our below laid-out logical organization from the top-left side (Fundamentals) to the right and down.

To follow the lessons on this web site, you should have installed either Microsoft Visual C# 2005 (Express Edition (which is free) or Professional), Borland C# Builder, sharpdevelop (which is free), or another environment or compiler that uses C#.
