其他几个类持有的同一类的模型集合

如何使用 Castle ActiveRecord 对以下内容进行建模？

我有两个类，客户和任务。

我想重用第三个类 Note，它存储在每个 Customer 和 Task 类的集合中。

public class Note
{
    public int ID { get; set; }
    public string Subject { get; set; }
    public string Body { get; set; }
}

public class Customer
{ 
    public int ID { get; set; }
    public IList<Note> Notes { get; set; }
}

public class Task
{
    public int ID { get; set; }
    public IList<Note> Notes { get; set; }
}

然后，我希望能够将 Notes 集合传递到 Customer 或 Task 类的相关 ASP.Net 页面中的 Gridview、Listview 或 Repeater。

How do I model the following using Castle ActiveRecord?

I have two classes, Customer and Task.

I would like to reuse a third class, Note, stored in a Collection in each of the Customer and Task classes.

public class Note
{
    public int ID { get; set; }
    public string Subject { get; set; }
    public string Body { get; set; }
}

public class Customer
{ 
    public int ID { get; set; }
    public IList<Note> Notes { get; set; }
}

public class Task
{
    public int ID { get; set; }
    public IList<Note> Notes { get; set; }
}

I would then like to be able to pass the Notes collection to a Gridview, Listview or Repeater in the relevant ASP.Net page for the Customer or Task classes.

我认为你需要的是实现类型层次结构。您可以在此处阅读相关内容。

我们确定了以下模式：

[ActiveRecord]
public class Note
{
    [PrimaryKey]
    public int ID { get; set; }

    [Property]
    public string Subject { get; set; }

    [Property]
    public string Body { get; set; }

    [BelongsTo]
    public Customer Customer { get; set; }

    [BelongsTo]
    public Customer Task{ get; set; }
}

[ActiveRecord]
public class Customer
{ 
    [PrimaryKey]
    public int ID { get; set; }

    [HasMany]
    public IList<Note> Notes { get; set; }
}

[ActiveRecord]
public class Task
{ 
    [PrimaryKey]
    public int ID { get; set; }

    [HasMany]
    public IList<Note> Notes { get; set; }
}

We settled on the following pattern:

[ActiveRecord]
public class Note
{
    [PrimaryKey]
    public int ID { get; set; }

    [Property]
    public string Subject { get; set; }

    [Property]
    public string Body { get; set; }

    [BelongsTo]
    public Customer Customer { get; set; }

    [BelongsTo]
    public Customer Task{ get; set; }
}

[ActiveRecord]
public class Customer
{ 
    [PrimaryKey]
    public int ID { get; set; }

    [HasMany]
    public IList<Note> Notes { get; set; }
}

[ActiveRecord]
public class Task
{ 
    [PrimaryKey]
    public int ID { get; set; }

    [HasMany]
    public IList<Note> Notes { get; set; }
}
