Binding a generic list to a repeater - ASP.NET

Question

I am trying to bind a List<AreaField> to a repeater. I have converted the list into an array by using the ToArray() method and now have a array of AreaField[]

Here's my class hierarchy

public class AreaFields
{
    public List<Fields> Fields { set; get; }
}

public class Fields
{
    public string Name { set; get; }
    public string Value {set; get; }
}

In the aspx, I would like to bind it a repeater (something like this)

DataBinder.Eval(Container.DataItem, "MyAreaFieldName1")

The MyAreaFieldName1 is the value of the Name property in the AreaFieldItem class.

You may want to create a subRepeater.

<asp:Repeater ID="SubRepeater" runat="server" DataSource='<%# Eval("Fields") %>'>
  <ItemTemplate>
    <span><%# Eval("Name") %></span>
  </ItemTemplate>
</asp:Repeater>

You can also cast your fields

<%# ((ArrayFields)Container.DataItem).Fields[0].Name %>

Finally you could do a little CSV Function and write out your fields with a function

<%# GetAsCsv(((ArrayFields)Container.DataItem).Fields) %>

public string GetAsCsv(IEnumerable<Fields> fields)
{
  var builder = new StringBuilder();
  foreach(var f in fields)
  {
    builder.Append(f);
    builder.Append(",");
  }
  builder.Remove(builder.Length - 1);
  return builder.ToString();
}
