Singleton Pattern - Default Property

Question

I\'ve been studying the Singleton pattern as it is used in the Settings class. Here\'s the relevant code from Settings.Designer.cs for my project AccessTest:

int         


        

Answer 1

Normaly, your Default property is called Instance

So that you can call your singleton like this :

Settings.Instance. X FUNCTION()

Design Pattern by Erich Gamma is pretty solid on design pattern. You should be able to find a PDF on the web easily :)

BTW you should also add this to your Default/Instance property

If(defaultInstance == null)
{
  defaultInstance = new Settings();
}
return defaultInstance

That way your singleton is never null and is lazy instantiated
