title: Lambda expression to manipulate a single field in a collection
body: <p>I have a collection of objects where an object has some fields. I need to format one of the fields in the collection and still maintain the integrity of the collection.</p>
  
  <p>Say for example I have a list of cars <code>var myCars = new List&lt;Car&gt;();</code>, and in that list of cars I want to change all color field from black to white by calling a <code>ChangeColor(string color)</code> method.
  Can I do that in one single line or do I need to make a new List and assign the fields one by one in a loop and call the change color method within that loop?</p>
  
  <p>I want to see if there is an 'one-liner'</p>
  
  <p>Thanks in advance.</p>
