Xml Literals in vb

Here I am creating an XElement in C#

   19         public static XElement PropertyTable(List<Property> propertyList)

   20         {

   21             XElement root = new XElement("div");

   22             root.Add(new XElement("div"

   23                 , new XAttribute("class", "propertyCount hand")

   24                 , string.Format("{0} properties", propertyList.Count)));

   25             XElement tableElement = new XElement("table", new XAttribute("class", "propertyTable"));

   26             root.Add(tableElement);

   27             XElement headerRow = new XElement("tr");

   28             headerRow.Add(new XElement("th", "Code"));

   29             headerRow.Add(new XElement("th", "Value"));

   30             tableElement.Add(headerRow);

   32

   33             foreach (Property p in propertyList)

   34             {

   35                 XElement projectRow = new XElement("tr");

   36                 projectRow.Add(new XElement("td", p.Code));

   37                 projectRow.Add(new XElement("td", p.Value));

   38                 tableElement.Add(projectRow);

   39             }

   40             return root;

   41         }

Here I am creating the EXACT SAME XElement in VB using xml literals

   19     Public Function PropertyTable(ByVal propertyList As List(Of [Property])) As XElement

   20       Dim root = <div>

   21                    <div class="propertyCount hand"><%= String.Format("{0} properties", propertyList.Count) %></div>

   22                    <table class="propertyTable">

   23                      <tr>

   24                        <th>Code</th>

   25                        <th>Value</th>

   26                      </tr>

   27                      <%= From p In propertyList Select _

   28                        <tr>

   29                          <td><%= p.Code %></td>

   30                          <td><%= p.Value %></td>

   31                        </tr> %>

   32                    </table>

   33                  </div>

   34       Return root

   35     End Function

passing data in an ntier application

http://stackoverflow.com/questions/917457

How do you pass data to layers in an n-tier application? I have mapped out 3 different methods.

A) generic .net objects generic data tables, Hashtables, generic datasets, strings, ints etc... then using the datasets to fill your business objects which get sent to the UI layer.

http://dabbleboard.com/draw?b=eiu165&i=26&c=54eef6f1ac01f03c85919518f4a24e798e57e133

Pro- No extra layers needed Con- Have to work with Generic datasets and tables in the business layer

B) using an entities layer that the other layers would reference. This layer would contain either strongly typed datasets or Plain Old C Objects. The objects would be mostly container data and very little logic. these would be the same objects sent to the UI layer.

http://dabbleboard.com/draw?b=eiu165&i=6&c=d0c2b346894a96b12bd3867f630e474a2af098fa

Pro- working with the same classes in all layers Con- adding a reference to entities.dll to all layers

C) use data transfer objects (conatiner objects only) defined in the DataAccess Layer. then using those objects to fill business objects which get sent to the UI layer.

http://dabbleboard.com/draw?b=eiu165&i=27&c=f886efa3f9d5eb4b45ddb02361c79cdcdaec0a9b

Pro- the business layer would not have to work with generic classes Con- working with two types of objects and you would have to hydrate the business objects with the transfer objects

We had a discussion at work and wanted to see what the community thought. I also added a link to the dabbleboard. please copy and create instead of editing.
Thanks
