使用存儲過程將對象列表保存到單獨的表中

Question

我有如下所示的對象列表。

public class Details 
    { 

     public string Reference { get; set; } 

     public List<Hotel> HotelDetails { get; set; } 
} 

我已經創建存儲過程來保存詳細信息表中的值。它的工作正常。以下是我的存儲過程。

USE [UL_SLHEV] 
GO 
/****** Object: StoredProcedure [dbo].[SP_EVoucherDetails_Insert] Script Date: 8/9/2017 11:20:31 AM ******/ 
SET ANSI_NULLS ON 
GO 
SET QUOTED_IDENTIFIER ON 
GO 

ALTER PROCEDURE [dbo].[SP_Details_Insert] 
    @XRequestReference varchar(15), 
AS 
BEGIN 

    DECLARE @RequestReference AS VARCHAR(15) = ISNULL(@XRequestReference,'') 


    INSERT INTO Voucher(
    RequestReference, 
    ) 

    VALUES(
    @RequestReference, 
    ) 

END 

在這裏，我必須在同一個保存方法和存儲過程中保存酒店詳細信息列表在另一個表中。以下是我用於在表格中保存酒店詳細信息的C＃代碼。

public EVoucherDetails SaveEVoucherDetails(EVoucherDetails detailsModel) 
     { 
      Func<SqlCommand, EVoucherDetails> injector = (cmd) => 
      { 
       cmd.Parameters.Add("@XRequestReference", SqlDbType.VarChar).Value = detailsModel.RequestReference; 

       var pList = new SqlParameter("@XHotelInfoDetails", SqlDbType.Structured); 
       pList.TypeName = "dbo.HotelInfo"; 
       pList.Value = GetHotelList(detailsModel.HotelInfo, detailsModel.RequestReference); 
       cmd.Parameters.Add(pList); 

      }; 
      return _sqlHelper.SqlSpExecute("SP_Details_Insert", injector); 
     } 

private List<SqlDataRecord> GetHotelList(List<HotelInfo> list, string RequestRef) 
{ 
    List<SqlDataRecord> datatable = new List<SqlDataRecord>(); 

    SqlMetaData[] sqlMetaData = new SqlMetaData[11]; 
    sqlMetaData[0] = new SqlMetaData("HotelID", SqlDbType.Int); 
    sqlMetaData[1] = new SqlMetaData("RequestReference", SqlDbType.VarChar, 15); 
    sqlMetaData[2] = new SqlMetaData("FromDate", SqlDbType.DateTime); 
    sqlMetaData[3] = new SqlMetaData("ToDate", SqlDbType.DateTime); 
    sqlMetaData[4] = new SqlMetaData("Nights", SqlDbType.Int); 
    sqlMetaData[5] = new SqlMetaData("MealPlan", SqlDbType.VarChar, 10); 
    sqlMetaData[6] = new SqlMetaData("StarCategory", SqlDbType.Int); 
    sqlMetaData[7] = new SqlMetaData("Status", SqlDbType.Int); 
    sqlMetaData[8] = new SqlMetaData("LastUpdatedBy", SqlDbType.VarChar, 50); 
    sqlMetaData[9] = new SqlMetaData("LastUpdatedDate", SqlDbType.DateTime); 
    sqlMetaData[10] = new SqlMetaData("CreatedDateTime", SqlDbType.DateTime); 
    sqlMetaData[10] = new SqlMetaData("CreatedUserId", SqlDbType.VarChar, 15); 

    foreach (var info in list) { 
     SqlDataRecord row = new SqlDataRecord(sqlMetaData); 
     int? hotelId = GetHoteId(info.HotelName); 
     row.SetValues(hotelId, RequestRef, info.FromDate, info.ToDate, info.Nights, info.MealPlan, info.StarCategory, info.Status, info.LastUpdatedBy, info.LastUpdatedDateTime, info.CreatedDateTime, info.CreatedUserId); 
     datatable.Add(row); 
    } 

    return datatable; 
} 

我不知道如何通過使用上述相同的存儲過程獲取酒店詳細信息。有人可以幫我嗎？

感謝

當使用SQL參數，它看起來像：

exec SP_Details_Insert "InputValueHere" 

你必須在你的多領域：

sqlMetaData[0] = new SqlMetaData("HotelID", SqlDbType.Int); 
    sqlMetaData[1] = new SqlMetaData("RequestReference", SqlDbType.VarChar, 15); 
    sqlMetaData[2] = new SqlMetaData("FromDate", SqlDbType.DateTime); 
    sqlMetaData[3] = new SqlMetaData("ToDate", SqlDbType.DateTime); 
    sqlMetaData[4] = new SqlMetaData("Nights", SqlDbType.Int); 
    sqlMetaData[5] = new SqlMetaData("MealPlan", SqlDbType.VarChar, 10); 
    sqlMetaData[6] = new SqlMetaData("StarCategory", SqlDbType.Int); 
    sqlMetaData[7] = new SqlMetaData("Status", SqlDbType.Int); 
    sqlMetaData[8] = new SqlMetaData("LastUpdatedBy", SqlDbType.VarChar, 50); 
    sqlMetaData[9] = new SqlMetaData("LastUpdatedDate", SqlDbType.DateTime); 
    sqlMetaData[10] = new SqlMetaData("CreatedDateTime", SqlDbType.DateTime); 
    sqlMetaData[10] = new SqlMetaData("CreatedUserId", SqlDbType.VarChar, 15); 

現在，如果你想Insert這一切記錄您的Stored Procedure無法處理此數據，因爲它只使用一個參數值VALUES( @RequestReference, )。

您需要在您的SP中有一個與您的數據相同的多參數，並循環您的data<List>以一次插入一個。
