C# is an object-oriented programming language developed by Microsoft as part of their .NET initiative, and later approved as a standard by ECMA and ISO. C# has a procedural, object-oriented syntax based on C that includes aspects of several other programming languages (most notably Delphi and Java) with a particular emphasis on simplification (fewer symbolic requirements than C , fewer declarative requirements than Java).
