在NHibernate的映射私有字段（与流利NH） [英] Mapping a Private Field in NHibernate (with Fluent NH)

问题描述

我想知道，我怎么能映射（用流利的NHibernate的）这种模式：

I'd like to know, How Could I map (with fluent nhibernate) this model:

public class Category
{
   private IList<Product> _products;
   public IEnumerable<Product> Products {
       get { return _products; }
   }
   /* others properties */   


   public Category() {
       _products = new List<Product>();
   }


   // to add a product i'd use something like this:
   public void AddProducts(Product product) {
      product.Category = this;
      _products.Add(products);
   }
}

今天，我使用的IList的属性，但我不希望暴露，如添加，删除，等等......在我的财产的方法，所以我觉得揭露的一个简单属性IEnumerable和封装一个IList像一个私人领域！

Today, I'm using a property of IList, but I don't want to expose the methods like "Add", "Remove", etc... on my property, So I think to expose a simple property of IEnumerable and encapsulate an IList like a private field!

所以，它是一个很好的初步实践？我怎么能使用NHibernate映射呢？

So, Is it a good pratice ? How could I map it using NHibernate?

感谢

干杯

推荐答案

如果你遵循的命名约定NHibernate的可以工作，而你的样品code呢，这是​​非常容易的：

If you follow a naming convention that NHibernate can work with, and your sample code does, it's very easy:

HasMany(x => x.Products).KeyColumn("ProductId")
    .AsBag().Inverse()
    .Access.CamelCaseField(Prefix.Underscore);
    // plus cascade options if desired

我觉得这是不是一个很好的做法多了，我觉得它几乎总是正确的做法。

I think this is more than a good practice, I think it's almost always the right practice.
