title: return multiple rows from an asmx service
body: <p>I have a web service method which i'd like to return multiple rows from a datatable.</p>
  
  <p>I am familiar with returning values from web service methods but not multiple rows from a datatable. What is the best way to go about doing this? Do I need to return an array or <code>list&lt;&gt;</code>?</p>
  
  <p>My code method is setup like this.</p>
  
  <pre><code>[WebMethod]
  public void UpdateBold(int count, float lat, float lng)
  {
  DataTable dt = new Gallery().DisplayNearestByLatLong(count, lat, lng);
  
  // return code here
  }
  </code></pre>
