body: <p>What is the most elegant way to return a string from a List
  ok, yeah, I know I can do something like</p>
  
  <pre><code>public string Convert(List&lt;int&gt; something)
  {
      var s = new StringBuilder();
      foreach(int i in something)
          s.AppendFormat("{0} ", i);
  
      return s.ToString();
  }
  </code></pre>
  
  <p>but i m sure there is a way to do this with lambdas
  I tried also to append to a stringbuilder but that is not doing whats expected</p>
