ASP Net Core 使用 ADO 存储到多个表

Question

我一直试图让 api 存储到多个表中，我创建了 2 个程序：

 CREATE PROCEDURE [dbo].[SaveDelivery]
(
@DNum INT,
@DName NVARCHAR(MAX),
@DriverNum INT,
@ReturnCode NVARCHAR(20) OUTPUT
)
AS
BEGIN
    SET @ReturnCode = 'C200'
    BEGIN
        INSERT INTO Delivery(DNum,DName,DriverNum)
        VALUES (@DNum,@DName,@DriverNum)
        SET @ReturnCode = 'C200'
    END
END

CREATE PROCEDURE [dbo].[SaveOrder]
(
@DNum INT,
@OrderNum INT,
@CustName NVARCHAR(MAX),
@CustAddress NVARCHAR(MAX),
@ContactNum NVARCHAR(MAX),
@TotalPrice Int,
@ReturnCode NVARCHAR(20) OUTPUT
)
AS
BEGIN
    SET @ReturnCode = 'C200'
    BEGIN
        INSERT INTO Orders(OrderNum,CustName,CustAddress,ContactNum,TotalPrice,DNum)
        VALUES (@OrderNum,@CustName,@CustAddress,@ContactNum,@TotalPrice,@DNum)
        SET @ReturnCode = 'C200'
    END
END

用我的 model

[DataContract]
    public class Delivery
    {
        [DataMember(Name = "DNum")]
        public int DNum { get; set; }
        [DataMember(Name = "DName")]
        public string DName { get; set; }
        [DataMember(Name = "DriverName")]
        public int DriverNum { get; set; }
        public List<Orders> order { get; set; }        
       
    }
    public class Orders
    {
        [DataMember(Name = "OrderNum")]
        public int orderNum { get; set; }
        //[DataMember(Name = "DNum")]
        public string CustName { get; set; }
        public string CustAddress { get; set; }
        public int contactNum { get; set; }
        public int totalPrice { get; set; }
   }

和我的 DBLink

public string SaveDelivery(Delivery model, string connString)
        {
            
            var outParam = new SqlParameter("@ReturnCode", SqlDbType.NVarChar, 20)
            {
                Direction = ParameterDirection.Output
            };
            SqlParameter[] param = {
                new SqlParameter("@DNum",model.DNum),
                new SqlParameter("@DName",model.DName),
                new SqlParameter("@DriverNum",model.DriverNum),
                outParam
            };
            SqlHelper.ExecuteProcedureReturnString(connString, "SaveDelivery", param);
            return (string)outParam.Value;
        }
        public string SaveOrder(Delivery model, string connString)
        {

            var outParam = new SqlParameter("@ReturnCode", SqlDbType.NVarChar, 20)
            {
                Direction = ParameterDirection.Output
            };
            SqlParameter[] param = {
                new SqlParameter("@DNum",model.DNum),
                new SqlParameter("@OrderNum", model.order.ForEach(Orders)),
                outParam
            };
            SqlHelper.ExecuteProcedureReturnString(connString, "SaveOrder", param);
            return (string)outParam.Value;
        }

问题是我找不到任何关于如何使用这种方法使用外键存储到数据库表的信息，而且我不想使用 EF Core。

这也是我的 controller，我希望 controller 为这两个表获取数据。

[HttpPost]
        //[Route("SaaveDelivery")]
        public IActionResult SaveDelivery([FromBody] Delivery model)
        {
            var msg = new Messages<Delivery>();
            var data = DbClientFactory<DeliveryDbClient>.Instance.SaveDelivery(model, appSettings.Value.DbConn);
            if (data == "C200")
            {
                msg.IsSuccess = true;  
            }
            return Ok(msg);
        }
