Possible to modify the C# that Linq To SQL generates?

[MetadataType(typeof(Product_Meta))]
 public partial class Product
 {
   public partial class Product_Meta
   {
     [Range(5, 50, ErrorMessage = "The product's reorder level must be greater than 5 and less than 50")]
     public object ReorderLevel { get; set; }
   }
 }
