Nhibernate和WCF IList<>冲突

问题描述

这是一个实体

<$公共类Channel：EntityBase
{

[DataMember]
公共虚拟IList< LocalChannel> LocalChannels {get;组; }
}

本地频道有一个字符串属性

这2个类映射流畅，并与许多关系正常工作。

问题出在wcf服务。

当我选择一个频道或所有频道。

localChannels列表是固定的大小。 （返回的ILIst类型是typed数组）

我希望我成为一个List。

Nhibernate不要让我这样写：

  public virtual List< LocalChannel> LocalChannels {get;组; } 
  

因为无法将他的集合转换为List

任何解决方案？

请参阅我的答案

NHibernate投影和DataContract投影是否有是一样的？我不太了解NHibernate，但你可以做这样的事情吗？

  public class Channel：EntityBase {
 
 //对于WCF 
 [DataMember（Name =LocalChannel）] 
 private List< LocalChannel>本地通道私人{
获得{返回新的List< LocalChannel>（LocalChannels）;} 
 set {LocalChannels = value;} 
} 
 
 //对于NHibernate 
公共虚拟IList< LocalChannel> LocalChannels {get; set;} 
} 
  

i'll use some sample code to demonstrate my problem...

this is an entity

public class Channel : EntityBase
{

    [DataMember]
    public virtual IList<LocalChannel> LocalChannels { get; set; }
}

local channel has a string property.

this 2 classes mapped fluently and works fine with the has many relation.

the problem is in the wcf service.

when i'm selecting a channel or all channels.

the localChannels list is fixed size. (the type of ILIst that returns is typed array)

i want i to be a List.

Nhibernate wont let me to write this:

public virtual List<LocalChannel> LocalChannels { get; set; }

becuase it cant cast his collections to List

and my proxy is written in code and not generated with svcutil so i cant change the collection type.

any solutions?

解决方案

See my answer to Manually change the ClientBase collection type from Array[] to List<>

Does the NHibernate projection and DataContract projection have to be the same? I don't know much about NHibernate, but can you do something like this?

public class Channel : EntityBase{

  //For WCF
  [DataMember(Name="LocalChannel")]
  private List<LocalChannel> LocalChannelsPrivate {
     get {return new List<LocalChannel>(LocalChannels);}
    set {LocalChannels=value;}
  }

  //For NHibernate
  public virtual IList<LocalChannel> LocalChannels {get; set;}
}
