Update one-to-many EntityKey using Foreign Key
- by User.Anonymous
To use by the easiest way Entity Framework, I use partial class to add Foreign Key on most important Entities Model.
For example, I have an Entity "CONTACT" which have "TITLE", "FUNCTION" and others.
When I update a CONTACT, with this code, Foreign Key are automatically updated :
public int? TitId
{
get
{
if (this.TITLE_TIT != null)
return TITLE_TIT.TIT_ID;
return new Nullable<int>();
}
set
{
this.TITLE_TITReference.EntityKey = new System.Data.EntityKey("Entities.TITLE_TIT", "TIT_ID", value);
}
}
But I have a join with ACTIVITY, that can have many CONTACT, and I don't know how to update EntityKey on setters.
public IEnumerable<EntityKeyMember> ActId
{
get
{
List<EntityKeyMember> lst = new List<EntityKeyMember>();
if (this.ACT_CON2 != null)
{
foreach (ACT_CON2 id in this.ACT_CON2.ToList())
{
EntityKeyMember key = new EntityKeyMember(id.CON_ID.ToString(),id.ACT_ID);
lst.Add(key);
}
}
return lst;
}
set
{
this.ACT_CON2.EntityKey = new System.Data.EntityKey("Entities.ACT_CON2", value);
}
}
How set many EntityKey ?
Thank you.
