title: Add comma thousand separator to decimal (.net)
body: <p>I have a decimal number, say 1234.500.</p>
  
  <p>I want to display it as 1,234.5.</p>
  
  <p>I'm currently converting it to a double to remove the trailing '0's.</p>
  
  <p><code>string.Format("{0:0,0}",1234.500)</code> removes the decimal place, and other formatting options seem to use two decimal places regardless.</p>
  
  <p>Can anyone offer insight?</p>
