title: Retrieve Pairs of Points from PointCollection?
body: <p>I have a collection of Points, stored in a PointCollection.</p>
  
  <p>I need the points in the collection to draw lines.  So, for example, if a point collection has four points, that will be two lines, as I use pairs of points in the collection to draw the line.  I am looking for a way, preferably using linq, and as few lines of code as possible, to essentially iterate through my PointCollection, extracting the next available pairs of points, and then drawing the line using the pairs of points.  Is there a way to do this using linq, lambda expressions, or extension method?</p>
  
  <p>Thanks.</p>
