entity-framework - Entity Framework の読み込み 親と子をグリッドに

Question

こんにちは、私のスキーマ edmx

私はこれを試します

protected void Page_Load(object sender, EventArgs e)
    {
         JeansEntities db = new JeansEntities();
         GridView1.DataSource = (db.Employes).Include("Address");
         GridView1.DataBind();
    }

そして、これは従業員テーブルのデータだけを提供します...わかりません...

ありがとう
