title: How to select all items in a radious in xyz space?
body: <p>So I have a <code>List</code> of <code>string</code>s formated like <code>{itemname}-{x}-{y}-{z}</code> (<code>x</code>, <code>y</code>, <code>z</code> are <code>typeof(int)</code> ). I have a point in 3d <code>xyz</code> space. I want using LINQ get all <code>List</code> items that are in some radious <code>R</code> (<code>typeof(int)</code>) from my point. How to do such thing with LINQ?</p>
