title: Using object/method name inside Linq method?
body: <p>What is the name of the "construction" at line 3 in which Contains is invoked, but without parentheses? Is it some kind of syntactic sugar?</p>
  
  <pre><code>string current = "02";
  string[] list = {"00", "01", "02", "03", "10"};
  if (list.Any(current.Contains)) {
    // logic
  }
  </code></pre>
  
  <p>I just can not figure out why and how it works nor what it is called?</p>
