title: String.Format vs ToString()
body: <p>Can anyone explain if there is any benefit in either one of the following methods:</p>
  
  <pre><code>decimal d = 12.0m;
  
  // 1. how I'd have done it
  myLabel.Text = d.ToString();
  
  // 2. how I saw someone do it today
  myLabel.Text = String.Format("{0}", d);
  </code></pre>
  
  <p>Just to clarify, I'm not querying what the methods do, I'm obviously happy with that, just if there is perhaps a performance benefit in one over the other in this specific example.
  I'm aware of the added flexibility of cultures and formatting offered by string.format(), but I'd always just 'tostring()' numerics to attach their value to a label, or text based property in general.</p>
  
  <p>To me, the string.format() option seems like more typing for no additional benefit here, but I wondered if there are any other 'under the hood' benefits of doing things one way vs the other.</p>
