Powiązanie listy generycznej z repeaterem - ASP.NET

Próbuję powiązać List<AreaField> z repeaterem. Przekonwertowałem listę do tablicy za pomocą metody ToArray() i teraz mam tablicę AreaField[]

Oto moja hierarchia klas

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

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

W aspx, chciałbym związać go repeater (coś takiego)

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

MyAreaFieldName1 jest wartością właściwości Name w klasie AreaFieldItem.

Możesz chcieć utworzyć podrepeater.

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

Możesz również rzucać swoje pola

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

W końcu możesz zrobić małą funkcję CSV i zapisać swoje pola za pomocą funkcji

<%# 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();
}

To zaskakująco proste...

Kod za:

// Here's your object that you'll create a list of
private class Products
{
    public string ProductName { get; set; }
    public string ProductDescription { get; set; }
    public string ProductPrice { get; set; }
}

// Here you pass in the List of Products
private void BindItemsInCart(List<Products> ListOfSelectedProducts)
{   
    // The the LIST as the DataSource
    this.rptItemsInCart.DataSource = ListOfSelectedProducts;

    // Then bind the repeater
    // The public properties become the columns of your repeater
    this.rptItemsInCart.DataBind();
}

Kod ASPX:

<asp:Repeater ID="rptItemsInCart" runat="server">
  <HeaderTemplate>
    <table>
      <thead>
        <tr>
            <th>Product Name</th>
            <th>Product Description</th>
            <th>Product Price</th>
        </tr>
      </thead>
      <tbody>
  </HeaderTemplate>
  <ItemTemplate>
    <tr>
      <td><%# Eval("ProductName") %></td>
      <td><%# Eval("ProductDescription")%></td>
      <td><%# Eval("ProductPrice")%></td>
    </tr>
  </ItemTemplate>
  <FooterTemplate>
    </tbody>
    </table>
  </FooterTemplate>
</asp:Repeater>
Mam nadzieję, że to pomoże!

Należy użyć metody ToList (). (Nie zapomnij o systemie.Przestrzeń nazw Linq)

Ex.:

IList<Model> models = Builder<Model>.CreateListOfSize(10).Build();
List<Model> lstMOdels = models.ToList();
