title: Split string input from textbox and convert it to array
body: <p>I am trying to get the input from a textbox and convert it to string in order to find the longest word using:</p>
  
  <pre><code>string longest = stringArray.OrderByDescending(s =&gt; s.Length).First();
  </code></pre>
  
  <p>For instance I have input in a text box "My sisters lives in UK"
  I want to have it in an array like ["My" , "sister", "lives", "in", "UK"] in order to use the code above to find the longest string.
  Thanks</p>
