C# 3.0: Auto-Implemented Property

Published 17 July 07 09:22 PM | adrian

Tired of writing this?

private int id;
public int Id
{
  get
  {
    return this.id;
  }
  set
  {
    this.id = value;
  }
}

Fear not! C# 3.0 will give way to a new structure for simple getter setter. The above code will become...

public string Test { get; set; }

Amazing!

Behind the scene, the compiler will generate an anonymous type as the backing field, and create getter/setter code as usual. Now what's anonymous type? Well, that's another question for another day!

How if I wanted the auto-generated code (private int id;) to be (protected int id;)?

Well, you can't! (at least right now before Beta2)

This is for rapid development, when more complex scenario happens, you would just extend the definitions.

So earlier this week I've blogged about the auto-implemented property . A thing it uses is anonymous
