這里我從存儲過程中檢索輸出參數Entity Framework(EDMX)（輸出參數是TransactionId）這里我想將TransactionId值傳輸到Scdid（在下一篇文章方法中）如何獲取TransactionId = Scdid in the controller我的API代碼是 public class StockcountheaderController : ApiController{    private adminv2Entities enqentities = new adminv2Entities();    [HttpPost]    private  void Stock([FromBody] List<spGetNewStockCountHeader_Result> jsonvalues)    {        foreach (spGetNewStockCountHeader_Result Datastock in jsonvalues)        {            ObjectParameter TransactionId = new ObjectParameter("TransactionId", typeof(Int32));            spGetNewStockCountHeader_Result Stockobject = new  spGetNewStockCountHeader_Result();            Stockobject.UserID = Datastock.UserID;            Stockobject.created = Datastock.created;            Stockobject.CompanyID = Datastock.CompanyID;            Stockobject.modified = Datastock.modified;            Stockobject.modifieduserid = Datastock.modifieduserid;            Stockobject.confirm = Datastock.confirm;            Stockobject.ShopId = Datastock.ShopId;            enqentities.spGetNewStockCountHeader(Datastock.UserID,  Datastock.created,                 Datastock.CompanyID, Datastock.modified,  Datastock.modifieduserid, Datastock.confirm,                Datastock.ShopId, TransactionId);        }    }    }
