C# is an object-oriented high-level programming language issued by Microsoft, which runs on the. NET Framework. And is scheduled to appear on the Microsoft Professional Developers Forum (PDC). C# is the latest achievement of Microsoft researcher Anders Hejlsberg. C# looks strikingly similar to Java; It includes procedures such as single inheritance, interface, almost the same syntax as Java, and compilation into intermediate code before running. However, C# is obviously different from Java. It draws on a feature of Delphi, is directly integrated with COM (Component Object Model), and is the leading role of Microsoft's. NET windows network framework.
