有人可以请它向我解释一下吗?我有这个存储过程:
ALTER proc [dbo].[Invoice_GetHomePageInvoices] (
@AreaIdList varchar(max)
, @FinancialYearStartDate datetime = null
, @FinancialYearEndDate datetime = null
) as
在代码中我试图这样称呼它:
var areasString = new SqlParameter("AreaIdList", "1,2");
var startDate = new SqlParameter("FinancialYearStartDate", financialYear.StartDate);
var endDate = new SqlParameter("FinancialYearEndDate", financialYear.EndDate);
return _db.Database.SqlQuery<HomePageInvoice>("Invoice_GetHomePageInvoices", areasString, startDate, endDate);
我收到了这个错误:
程序或功能'Invoice_GetHomePageInvoices'需要参数 '@AreaIdList',未提供。
说什么?我提供了那个参数。有人可以给我一些关于如何修复的见解吗?

您需要这样称呼它:
var areasString = new SqlParameter("AreaIdList", "1,2");
var startDate = new SqlParameter("FinancialYearStartDate", financialYear.StartDate);
var endDate = new SqlParameter("FinancialYearEndDate", financialYear.EndDate);
return _db.Database.SqlQuery<HomePageInvoice>("EXEC Invoice_GetHomePageInvoices @AreaIdList, @FinancialYearStartDate, @FinancialYearEndDate", areasString, startDate, endDate);
我相信你也可以缩短它,比如:
return _db.Database.SqlQuery<HomePageInvoice>("EXEC Invoice_GetHomePageInvoices {0}, {1}, {2}", "1,2", financialYear.StartDate, financialYear.EndDate);

可能需要参数值:
return _db.Database.SqlQuery<HomePageInvoice>("Invoice_GetHomePageInvoices", areasString.Value, startDate.Value, endDate.Value)
