Introduction to C#

What is C# ?

C# is intended to be a simple, modern, general-purpose, object-oriented programming language.

Its development team is led by Anders Hejlsberg. The most recent version is C# 4.0, which was released on April 12, 2010.

C# (pronounced "see sharp") is a multi-paradigm programming language encompassing imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming disciplines.

It was developed by Microsoft within the .NET initiative and later approved as a standard by Ecma (ECMA-334) and ISO (ISO/IEC 23270).

C# is one of the programming languages designed for the Common Language Infrastructure.

Features of C#

Some notable distinguishing features of C# are:

There are no global variables or functions. All methods and members must be declared within classes. Static members of public classes can substitute for global variables and functions. Managed memory cannot be explicitly freed instead, it is automatically garbage collected. Garbage collection addresses the problem of memory leaks by freeing the programmer of responsibility for releasing memory which is no longer needed. In addition to the try...catch construct to handle exceptions, C# has a try...finally construct to guarantee execution of the code in the finally block. Multiple inheritance  is not supported by C#, although a class can implement any number of interfaces.
