尝试在邮件正文中提交带有对象的队列邮件,但在BrokeredMessage的以下行中接收异常
QueueClient queueClient = QueueClient.CreateFromConnectionString(_connectionString, _queuePathName);
var data = new ABSurvey
{
name = "somename",
version = 1,
language = "eng",
SelfSurvey = new Survey()
{
SurveyItems = new List<ISurveyItem>() { new SurveyItem(){IsSelected = true, ItemId = 1}},
SurveyPerception = Constants.Perception.Self
},
SelfConcept = new Survey()
{
SurveyItems = new List<ISurveyItem>() { new SurveyItem(){IsSelected = true, ItemId = 1}},
SurveyPerception = Constants.Perception.SelfConcept
}
};
BrokeredMessage message = new BrokeredMessage(data);
queueClient.Send(message);
异常消息 - 输入&#39;。调查&#39;数据合同名称&#39;调查:http://schemas.datacontract.org/2004/07/namespace&#39;不是预期的。考虑使用DataContractResolver或将任何静态未知的类型添加到已知类型列表中 - 例如,使用KnownTypeAttribute属性或将它们添加到传递给DataContractSerializer的已知类型列表中。
这些是我的模型 -
[DataContract]
public class ABSurvey
{
[DataMember] public string name;
[DataMember] public int version;
[DataMember] public string language;
[DataMember] public ISurvey SelfSurvey;
[DataMember] public ISurvey SelfConcept;
}
[DataContract]
public class SurveyItem : ISurveyItem
{
[DataMember]
public int ItemId { get; set; }
[DataMember]
public bool IsSelected { get; set; }
public SurveyItem()
{
ItemId = -1;
IsSelected = false;
}
}
[DataContract]
public class Survey : ISurvey
{
[DataMember]
public IList<ISurveyItem> SurveyItems { get; set; }
[DataMember]
public Constants.Perception SurveyPerception { get; set; }
public Survey()
{
SurveyItems = new List<ISurveyItem>();
}
}
public interface ISurvey
{
[DataMember]
IList<ISurveyItem> SurveyItems { get; set; }
[DataMember]
Constants.Perception SurveyPerception { get; set; }
}
public interface ISurveyItem
{
[DataMember]
int ItemId { get; set; }
[DataMember]
bool IsSelected { get; set; }
}
请帮助找到问题。

您的数据合约缺少[KnownType]
属性,这就是您的邮件无法序列化的原因。详细说明可以在hehe找到。
只需添加[KnownType]属性即可告诉序列化器可以使用哪种具体实现:
[KnownType(typeof(Survey))]
[DataContract]
public class ABSurvey
{
[DataMember]
public string name;
[DataMember]
public int version;
[DataMember]
public string language;
[DataMember]
public ISurvey SelfSurvey;
[DataMember]
public ISurvey SelfConcept;
}
[KnownType(typeof(SurveyItem))]
[DataContract]
public class Survey : ISurvey
{
[DataMember]
public IList<ISurveyItem> SurveyItems { get; set; }
public Survey()
{
SurveyItems = new List<ISurveyItem>();
}
}
