如何使用XMLSerializer的一个城堡的ActiveRecord包含一个IList&LT; T&GT;会员 [英] How to use XMLSerializer with a Castle ActiveRecord containing an IList<T> member
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?
推荐答案
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); }
}
}
