我想生成一个价格行情表，存储过程如下，现在知道起始时间、结束时间分别是lda_start,lda_end,
请问在.net(c#)中如何调用执行这个存储过程.小妹很愚笨，请多指教。
CREATE PROCEDURE OPR.WEB_SP_GETPRICESINFO
(
@startTime datetime ,
@endTime datetime
)
AS
if @startTime is null
begin
raiserror('没有指定要检索的单价的起始时间。', 16, 1)
return
end

if @endTime is null
begin
raiserror('没有指定要检索的单价的终止时间。', 16, 1)
return
end

if @startTime > @endTime
begin
declare @time datetime
set @time = @endTime
set @endTime = @startTime
set @startTime = @time
end

create table #WEB_PRICESINFO
(

)

where (OPR.ICTRADES.VEGCODE = @code) and (OPR.ICTRADES.FIRSTWEIGHTIME between @startTime and @endTime)

if @@ERROR <> 0
begin
close price_cur
deallocate price_cur
return
end

if @@ROWCOUNT = 0
begin
