Entity Framework里不用查询直接更新的办法

直接贴示例代码吧

public static void UpdateOwnerAndCondo(int buildingID, Action<Building> updateAction)
{
    Building building = new Building();
    building.ID = buildingID;
    using (CafContext context = CafContext.Create())
    {
        context.Configuration.ValidateOnSaveEnabled = false;
        context.Entry<Building>(building).State = EntityState.Unchanged;
        updateAction(building);
        context.SaveChanges();
    }
    building.ID = buildingID;
}
