如何使用XMLSerializer的一个城堡的ActiveRecord包含一个IList＆LT; T＆GT;会员

问题描述：

我想使用XmlSerializer的与它看起来像下面的一个城堡活动记录类：

I am trying to use the XMLSerializer with a castle active record class which looks like the following:

[ActiveRecord("Model")]
public class DataModel : ActiveRecordBase
{
    private IList<Document> documents;

    [XmlArray("Documents")]
    public virtual IList<Document> Documents
    {
        get { return documents; }
        set
        {
            documents = value;    
        }
    }
}

不过，XmlSerializer的运行，因为IList接口的麻烦。（引发异常：无法序列类型的成员DataModel.Documents''System.Collections.Generic.IList`1 .... ）

However, the XMLSerializer runs into trouble because of the IList interface. (Raises exception: Cannot serialize member 'DataModel.Documents' of type 'System.Collections.Generic.IList`1....)

我在其他地方看，这是在XmlSerializer的限制和建议的解决方法是将其声明为名单，其中，T＆GT; 接口，而不是

I read elsewhere that this is a limitation in the XMLSerializer and the recommended workaround is to declare it as a List<T> interface instead.

因此，我试图改变的IList＆LT;文件＆GT; 到名单，其中，文件＆GT; 。这导致的ActiveRecord引发异常： 属性DataModel.Documents类型必须是接口（IList的，的ISet，IDictionary的还是他们的通用零件柜）。不能使用的ArrayList或List作为属性类型。

Therefore I tried changing the IList<Document> to List<Document>. This causes ActiveRecord to raise an Exception: Type of property DataModel.Documents must be an interface (IList, ISet, IDictionary or their generic counter parts). You cannot use ArrayList or List as the property type.

所以，问题是：你如何使用XmlSerializer的一个城堡的ActiveRecord包含一个IList成员

So, the question is: How do you use the XMLSerializer with a Castle ActiveRecord containing an IList member?

答

有趣的...最好的，我可以建议是使用 [XmlIgnore] 在文件 - 和它的ActiveRecord有忽视成员的类似的方式？你可以这样做：

Interesting... the best I can suggest is to use [XmlIgnore] on Documents - and does ActiveRecord have a similar way of ignoring a member? You could do something like:

[XmlIgnore]
public virtual IList<Document> Documents
{
    get { return documents; }
    set
    {
        documents = value;    
    }
}

[Tell ActiveRecord to ignore this one...]
[XmlArray("Documents"), XmlArrayItem("Document")]
[Browsable(false), EditorBrowsable(EditorBrowsableState.Never)]
public Document[] DocumentsSerialization {
    get {
         if(Documents==null) return null;
         return Documents.ToArray(); // LINQ; or do the long way
    }
    set {
         if(value == null) { Documents = null;}
         else { Documents = new List<Document>(value); }
    }
}
