In PHP it's common practice to pass an array as options for a class, and then merge that array with a set another array that holds the defaults.

Something like this.

class MyObject
{
     private static $defaults = array('value'=>10);
     private $settings;

     public function Something(array $settings = array())
     {
          $this->settings = array_merge(static::defaults,$settings);
     }
}

You can do the something in JavaScript using jQuery or other libraries that introduce the merge function. These scripts let you take two Javascript objects and merge them together. Allowing you to use one as the defaults, and another to override those defaults.

I've found this pattern very useful, because it allows you to configure a large set of defaults but only assign the settings you need.

Is there anyway to do something like this in C#?

I could write a function that uses reflection to do this on public properties, but I was thinking something like this must have already been done.

EDIT:

This question has been asked before on stack, but not answered in a way that provides the same simplicity as what can be done in PHP and Javascript.
