return this;
}

public ShopViewData WithProduct(Product product)
{

return this;
}

public ShopViewData WithProducts(IEnumerable<Product> products)
{

return this;
}

public ShopViewData WithRoles (IEnumerable<Role> roles)
{

}

public ShopViewData WithUser(User user)
{

return this;
}

public ShopViewData WithUsers(IEnumerable<User> users)
{

return this;
}

public ShopViewData WithBasket(Basket basket)
{
this.Basket = basket;
return this;
}

public ShopViewData WithOrders(PagedList<Order> orders)
{
this.Orders = orders;
return this;
}

public ShopViewData WithOrder (Order order)
{
this.Order = order;
return this;
}

public ShopViewData WithOrderSearchCriteria(OrderSearchCriteria orderSearchCriteria)
{
this.OrderSearchCriteria = orderSearchCriteria;
return this;
}

public ShopViewData WithCountries(IEnumerable<Country> countries)
{
this.Countries = countries;
return this;
}

public ShopViewData WithCountry(Country country)
{
this.Country = country;
return this;
}

public ShopViewData WithCardTypes(IEnumerable<CardType> cardTypes)
{
this.CardTypes = cardTypes;
return this;
}

public ShopViewData WithPostage(Postage postage)
{
this.Postage = postage;
return this;
}

public ShopViewData WithPostages(IEnumerable<Postage> postages)
{
this.Postages = postages;
return this;
}

public ShopViewData WithTotalPostage(PostageResult postageResult)
{
this.PostageResult = postageResult;
return this;
}

public ShopViewData WithCard(Card card)
{
this.Card = card;
return this;
}

public ShopViewData WithStockItems(IEnumerable<StockItem> stockItems)
{
this.StockItems = stockItems;
return this;
}

public ShopViewData WithContents (IEnumerable<Content> contents)
{
this.Contents = contents;
return this;
}

public ShopViewData WithOrderStatuses (IEnumerable<OrderStatus> orderStatuses)
{
this.OrderStatuses = orderStatuses;
return this;
}
}

为了便于使用，Suteki.Shop还以静态属性的方式进行了封闭，最终以ShopView这个类开放出来提供给Action和View使用，其实现代码如下：

/// <summary> /// So you can write /// ShopView.Data.WithProducts(myProducts); /// </summary> public class ShopView { public static ShopViewData Data { get { return new ShopViewData(); } } }

下面以“编辑用户”这个Action来看
