silverlight - WCF Ria 服务返回带有子列表的复杂对象

Question

当我构建要由 WCF RIA 服务返回给 silverlight 的模型时，silverlight 客户端中不会显示列表属性。

班级：

public class Batch
{
    [DataMember]
    public DateTime Time { get; set; }

    [DataMember]
    public List<BasicInfoModel> Accepted { get; set; }

    [DataMember]
    public List<BasicInfoModel> UnAccepted { get; set; }
}

public class Batch
{
    [Key]
    [DataMember]
    public int Id { get; set; }

    [DataMember]
    public string Name { get; set; }
}

在客户端时，似乎没有生成列表，例如，这是我加载的回调事件：

private void Callback(LoadOperation<Batch> loadOperation)
{
     //there is no such property as `Accepted`
     var acceptedList = loadOperation.Entities.FirstOrDefault().Accepted;
}

难道我做错了什么？

Answer 1

我想，你错过了 DataContract 属性，例如

[DataContract]
public class Batch
{
    [DataMember]
    public DateTime Time { get; set; }

    [DataMember]
    public List<BasicInfoModel> Accepted { get; set; }

    [DataMember]
    public List<BasicInfoModel> UnAccepted { get; set; }
}
