WCF ria 服务返回复杂类型列表
我有一个复杂类型实体
public class ComplexEntity : ComplexObject
{
private int _ID;
private string _Name;
private int _ParentID;
[Key]
[DataMember]
public int ID { get;set;}
[DataMember]
public string Name {get;set;}
[DataMember]
public int ParentID {get;set;}
}
、另一个实体
[DataContract]
public class ComplexEntitiesList : ComplexObject
{
[DataMember]
[Include]
[Association("CEntities_CEntity","ID","ParentID")]
public List<CompelxEntity> List {get;set;}
[Key]
[DataMember]
public int ID {get;set;}
public int LKEntitiesList()
{
List = new List<LKEntity>;
}
和一种方法：
[Invoke]
public ComplexEntitiesList GetPS()
{
return new ComplexEntitiesList() { List = /*..some logic*/});
}
在服务器端一切都很完美，但在客户端列表为空 有什么线索吗？ }
I have a complex type entity
public class ComplexEntity : ComplexObject
{
private int _ID;
private string _Name;
private int _ParentID;
[Key]
[DataMember]
public int ID { get;set;}
[DataMember]
public string Name {get;set;}
[DataMember]
public int ParentID {get;set;}
}
and another one
[DataContract]
public class ComplexEntitiesList : ComplexObject
{
[DataMember]
[Include]
[Association("CEntities_CEntity","ID","ParentID")]
public List<CompelxEntity> List {get;set;}
[Key]
[DataMember]
public int ID {get;set;}
public int LKEntitiesList()
{
List = new List<LKEntity>;
}
and a method:
[Invoke]
public ComplexEntitiesList GetPS()
{
return new ComplexEntitiesList() { List = /*..some logic*/});
}
On the server side everything's perfect however the list comes empty at the client side
Any clues?

我认为 Include 不适用于 Invoke-Operations。查看 silverlight.net 上的此问题并查看 Colin Blairs 的回答。您的方法 GetPs() 应该返回一个包含复杂对象的普通集合（又名列表）。
I think the Include will not work wit Invoke-Operations. Take a look at this question on silverlight.net and see Colin Blairs answer. Your method GetPs() should return a normal collection (aka. List) containing your complex objects.
