问题描述

使用Entity Framework CTP 5,我试图在我的课程中列出一个外键列表.但是我不断收到一条错误消息,提示找不到相关的收件人."

Using Entity Framework CTP 5 I am trying to make a list of foreign keys in my class.But I keep getting an error which says RelatedTo can not be found.

这是代码:

public class VertragsVerweis : GenericBLL
{
    [Key]
    public String Uid
    {
        get;
        set;
    }

    public String VertagsVerweisNr
    {
        get;
        set;
    }

    public String Bezeichnung
    {
        get;
        set;
    }

    public Boolean Reparatur
    {
        get;
        set;
    }

    [RelatedTo(RelatedProperty="Artikel")]
    public List<Artikel> Artikelen
    {
        get;
        set;
    }
}

这给了我错误:

由于某种原因,它确实从System.ComponentModel.DataAnnotations中识别键属性.为什么它不识别RelatedTo?

For some reason it DOES recognize the Key Attribute from System.ComponentModel.DataAnnotations. Why does it not recognize RelatedTo?

推荐答案

I would recommend you upgrade to EF4.1 ... Perhaps your problem is solved with that. If not - update your question :)
