title: List of strings to one string
body: <p>Lets say you have a:</p>
  
  <pre><code>List&lt;string&gt; los = new List&lt;string&gt;();
  </code></pre>
  
  <p>In this crazy functional world we live in these days which one of these would be best for creating one string by concatenating these:</p>
  
  <pre><code>String.Join(String.Empty, los.ToArray());
  
  StringBuilder builder = new StringBuilder();
  los.ForEach(s =&gt; builder.Append(s));
  
  string disp = los.Aggregate&lt;string&gt;((a, b) =&gt; a + b);
  </code></pre>
  
  <p>or Plain old StringBuilder foreach</p>
  
  <p>OR is there a better way?</p>
