You should use ToList   method    Don t forget about System Linq namespace   ex    IList lt Model gt  models   Builder lt Model gt  CreateListOfSize 10  Build    List lt Model gt  lstMOdels   models ToList

It is surprisingly simple     Code behind      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 lt Products gt  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        ASPX code    lt asp Repeater ID  rptItemsInCart  runat  server  gt     lt HeaderTemplate gt       lt table gt         lt thead gt           lt tr gt               lt th gt Product Name lt  th gt               lt th gt Product Description lt  th gt               lt th gt Product Price lt  th gt           lt  tr gt         lt  thead gt         lt tbody gt     lt  HeaderTemplate gt     lt ItemTemplate gt       lt tr gt         lt td gt  lt    Eval  ProductName     gt  lt  td gt         lt td gt  lt    Eval  ProductDescription    gt  lt  td gt         lt td gt  lt    Eval  ProductPrice    gt  lt  td gt       lt  tr gt     lt  ItemTemplate gt     lt FooterTemplate gt       lt  tbody gt       lt  table gt     lt  FooterTemplate gt   lt  asp Repeater gt    I hope this helps

You may want to create a subRepeater    lt asp Repeater ID  SubRepeater  runat  server  DataSource   lt    Eval  Fields     gt   gt     lt ItemTemplate gt       lt span gt  lt    Eval  Name     gt  lt  span gt     lt  ItemTemplate gt   lt  asp Repeater gt    You can also cast your fields   lt      ArrayFields Container DataItem  Fields 0  Name   gt    Finally you could do a little CSV Function and write out your fields with a function   lt    GetAsCsv   ArrayFields Container DataItem  Fields    gt   public string GetAsCsv IEnumerable lt Fields gt  fields      var builder   new StringBuilder      foreach var f in fields          builder Append f       builder Append             builder Remove builder Length - 1     return builder ToString
