EF调用sp，EF自动生成返回类型
在sp中添加下面的红色部分，就是执行sp时的返回类型，后面在EF中添加该sp后，EF会在DBContext文件中，自动生成调用该sp的代码，包括返回类型等，如下：
public virtual ObjectResult<SP_CustomerRequestWriteoff_Result> SP_CustomerRequestWriteoff(Nullable<int> qrTransID, Nullable<int> campaignID, string openID, string buyList, string giftList)
{
var qrTransIDParameter = qrTransID.HasValue ?
new ObjectParameter("qrTransID", qrTransID) :
new ObjectParameter("qrTransID", typeof(int));
var campaignIDParameter = campaignID.HasValue ?
new ObjectParameter("campaignID", campaignID) :
new ObjectParameter("campaignID", typeof(int));
var openIDParameter = openID != null ?
new ObjectParameter("openID", openID) :
new ObjectParameter("openID", typeof(string));
var buyListParameter = buyList != null ?
new ObjectParameter("buyList", buyList) :
new ObjectParameter("buyList", typeof(string));
var giftListParameter = giftList != null ?
new ObjectParameter("giftList", giftList) :
new ObjectParameter("giftList", typeof(string));
return ((IObjectContextAdapter)this).ObjectContext.ExecuteFunction<SP_CustomerRequestWriteoff_Result>("SP_CustomerRequestWriteoff", qrTransIDParameter, campaignIDParameter, openIDParameter, buyListParameter, giftListParameter);
}
然后直接调用即可，如下：
public static Result ExportPeriodDetailReport(DateTime? beginDate, DateTime? endDate, string activityId, string storeCode, string flag)
{
using (var db = new SAISC_4S_PotentialEntities())
{
//调用存储过程
if (flag == "1")
{
var query = db.sp_Rpt_Act_Weekly_List(beginDate, endDate, activityId, storeCode).ToList();
return new Result(true, "", query);
}
}
}
