MongoDB C#驱动程序:忽略插入时的属性 [英] MongoDB C# Driver: Ignore Property on Insert

问题描述

我使用的是MongoDB C#官方驱动器v0.9.1.26831，但我想知道是否有POCO类，无论如何都将忽略某些属性.

I am using the Official MongoDB C# Drive v0.9.1.26831, but I was wondering given a POCO class, is there anyway to ignore certain properties from getting inserted.

例如，我有以下课程:

public class GroceryList
{
    public string Name { get; set; }
    public FacebookList Owner { get; set; }
    public bool IsOwner { get; set; }
}

有没有办法让我插入GroceryList对象时不会插入 IsOwner ? 基本上，我从数据库中获取对象，然后在应用程序层中设置IsOwner属性，然后将其返回给控制器，然后该控制器将对象映射到视图模型.

Is there a way, for the IsOwner to not get inserted when I insert a GroceryList object? Basically, I fetch the object from the database then set the IsOwner property in the app layer and then return it back to the controller, which than maps the object to a view model.

希望我的问题有道理.谢谢！

Hope my question makes sense. thanks!

推荐答案

看起来[BsonIgnore]属性完成了这项工作.

It looks like the [BsonIgnore] attribute did the job.

public class GroceryList : MongoEntity<ObjectId>
{
    public FacebookList Owner { get; set; }
    [BsonIgnore]
    public bool IsOwner { get; set; }
}
