Orcas - First try

After reading a post by Scott Guthrie on the new C# Orcas language features I decided to download Orcas and try them out.  (excited)

The new features I practiced with and love are:

  1. Object initializers Example: Prior to Orcas:

Person person = new Person(); person.FirstName = “Scott”; person.LastName = “Guthrie”; person.Age = 32;

Orcas:

Person person = new Person { FirstName=“Scott”, LastName=“Guthrie”, Age=32 };

I personally like this because I like to have a constructor initializer for all my objects.  That is no longer necessary. =)

  1. Collection initilizers Orcas:

List people = new List();

people.Add( new Person { FirstName = “Scott”, LastName = “Guthrie”, Age = 32 } ); people.Add( new Person { FirstName = “Bill”, LastName = “Gates”, Age = 50 } ); people.Add( new Person { FirstName = “Susanne”, LastName = “Guthrie”, Age = 32 } );

The new feature I played with that I’m still not to sure about is:

  1. Automatic Properties Example: Prior to Orcas:

public class Person {

private string _firstName; private string_lastName; private int _age;

public string FirstName {

get { return _firstName; } set { _firstName = value; } }

public string LastName {

get { return _lastName; } set { _lastName = value; } }

public int Age {

get { return _age; } set { _age = value; } } }

Orcas:

public class Person { public string FirstName { get; set; } public string LastName { get; set; } public int Age { get; set; } }

Guthrie’s post has links to Bart deSmart’s blog where he shows what happens under the covers for each of these features.

More to come.
