I have this table. And i want "one to many" in it on ParentID. I want choose parent id from list and want to do it by Entity framework or fluent api, but don't know them good.
You would want to do something like this:
[Table("Menus")]
public class Menus
{
[Key]
public int ID { get; set; }
public string MenuName { get; set; }
[ForeignKey("ParentMenu")]
public int ParentID { get; set; }
public virtual Menu ParentMenu { get; set; }
public virtual List<Menu> ChildMenus { get; set; }
}
Everything work. Thanks. I delete all rows in my tables and then create migrations. But the property must be nullable:
public int? ParentID { get; set; }
