C# 2.0 - Introductory

Hi,

This blog post summarizes the new features of C# 2.0.

Below are the new features been introduced.

§ Partial Classes

§ Static Classes

§ Generic Classes

§ Anonymous methods

§ Iterators

§ Nullable Types

Partial Classes	- Partial types allow classes, structs, and interfaces to be broken into multiple pieces stored in different source files for easier development and maintenance.
Static Classes
Generic Classes	- Generics permit classes, structs, interfaces, delegates, and methods to be parameterized by the types of data they store and manipulate. - Provide stronger compile-time type checking. - Require fewer explicit conversions between data types - Reduces the need for boxing operations and runtime type checks
Anonymous methods	- Anonymous methods allow code blocks to be written “in-line” where delegate values are expected. - Anonymous methods are similar to lambda functions in the Lisp programming language. - C# 2.0 supports the creation of “closures” where anonymous methods access surrounding local variables and parameters.
Iterators	- Iterators are methods that incrementally compute and yield a sequence of values. - Iterators make it easy for a type to specify how the foreach statement will iterate over its elements.
Nullable Types	-

The language extensions in C# 2.0 were designed to ensure maximum compatibility with existing code. For example, even though C# 2.0 gives special meaning to the words where yield , and partial

in certain contexts, these words can still be used as identifiers.

Indeed, C# 2.0 adds no new keywords because such keywords could conflict with identifiers in existing code.

Hope this helps
