我有一个表 Country.CountryID 是另一个表 Energy 上的外键。当我尝试删除 Country 表中的记录时,我应该收到一条显示外键关系的消息。该消息还应该显示子表的名称。我使用过 jtable。

编辑:模型是:-

public class Country
    {
        [Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        public int CountryID { get; set; }

        [Required(ErrorMessage = "The Country Name is required")]        
        public string CountryName { get; set; }
}

public class Energy
    {
        [Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        public int EnergyID { get; set; }

        [Required(ErrorMessage = "Country is required.")]
        public int? CountryID { get; set; }
        [ForeignKey("CountryID")]
        public virtual Country Countries { get; set; }
}

在控制器内部,我这样写:-

SqlException sqlException = ex.InnerException != null ? ex.InnerException.InnerException as SqlException : null;
                if (sqlException != null) return Json(new { Result = "ERROR", Message = "Sorry! unable to delete." });
                else return Json(new { Result = "ERROR", Message = ex.Message });

如何在 mvc3 中获取相关表名?可以使用linq吗?
