Function from: http://robertnyman.com/2005/11/07/the-ultimate-getelementsbyclassname/

function getElementsByClassName(className, tag, elm){
  var testClass = new RegExp("(^|\\s)" + className + "(\\s|$)");
  var tag = tag || "*";
  var elm = elm || document;
  var elements = (tag == "*" && elm.all)? elm.all : elm.getElementsByTagName(tag);
  var returnElements = [];

  var length = elements.length;

In summary, one easy fix is manually change the LINQ data type from Binary (System.Data.Linq.Binary) to byte[] (System.Byte[])

public static string GetHTMLFromURL(string URL)
{   
  // Download page content   
  WebClient MyWebClient = new WebClient();   
  Byte[] PageHTMLBytes;   
  PageHTMLBytes = MyWebClient.DownloadData(URL);    
  // Convert result from byte array to string   
  UTF8Encoding oUTF8 = new UTF8Encoding();   
  return oUTF8.GetString(PageHTMLBytes); 
}
