在EF Code First中，是否可以封装应保留在数据存储中的属性？ [英] In EF Code First is it possible to encapsulate properties that should be persisted to the data store?

问题描述

因此，假设我有一个POCO，我希望EF Code First可以持久保存到数据存储中：

So let's say I've got a POCO that I want EF Code First to persist to a data store:

public class Campaign
{
    public string Name { get; set; }
    public double GoalAmount { get; set; }
    private double AmountRaised { get; set; }
    public bool GoalMet
    {
        get
        {
            return AmountRaised >= GoalAmount;
        }
    }
}

现在，无论出于何种原因，我不希望在对象外部访问 AmountRaised 属性，但是我 do 希望它持久保存到数据存储中。

Now, for whatever reason, I don't want the AmountRaised property to be accessible outside the object, but I do want it persisted to the data store. Is this possible with EF Code First?

推荐答案

您可以将其设置为内部，并确保包含POCO /域对象的项目与 DbContext 类位于同一程序集中。或者，您可以在包含POCO的文件中声明朋友程序集：

You can make it internal and make sure that the project that contains the POCOs / domain objects are in the same assembly as your DbContext classes. Or you can declare "friend" assemblies in the files that contain your POCOs:

[assembly：InternalsVisibleTo（ MyOther.Assembly）]
