stored procedure returning only reference fields - linq-to-sql

Question

have a stored procedure with 1 input and 2 reference parameters. When assigning the stored procedure to a linq-query the query is not executed. What should I do to really execute the query which fills the 2 reference parameters. All examples I found at the internet use 'foreach' statements but the sp isn't returning a list of results.
the stored procedure:
ALTER PROCEDURE [dbo].[usp_GetStraatenPlaatsnaam]
-- Add the parameters for the stored procedure here
-- <#Param1, sysname, #p1> <Datatype_For_Param1, , int> = <Default_Value_For_Param1, , 0>,
-- <#Param2, sysname, #p2> <Datatype_For_Param2, , int> = <Default_Value_For_Param2, , 0>
#POSTCODE nvarchar(6)
,#STRAAT nvarchar(17) out
,#PLAATS nvarchar(18) out
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
SELECT
#STRAAT = PCT_STRAATNAAM_TNT
,#PLAATS = PCT_WOONPLAATS_TNT
FROM
PCTR
WHERE
PCT_POSTCODE = #POSTCODE
END
The Procedure is a given fact with no allowance to change. How can I call and execute this procedure using LinqToSQL? The Procedure is already used for a number of other processes and has worked for ages.

You are using output parameter as 'out' keyword which merely used in PL-Sql(Oracle)....Instead, you have to use 'OUTPUT' keyword for output parameter in T-Sql(Sql Server)....
ALTER PROCEDURE [dbo].[usp_GetStraatenPlaatsnaam]
-- Add the parameters for the stored procedure here
-- <#Param1, sysname, #p1> <Datatype_For_Param1, , int> = <Default_Value_For_Param1, , 0>,
-- <#Param2, sysname, #p2> <Datatype_For_Param2, , int> = <Default_Value_For_Param2, , 0>
#POSTCODE nvarchar(6)
,#STRAAT nvarchar(17) OUTPUT
,#PLAATS nvarchar(18) OUTPUT
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
SELECT
#STRAAT = PCT_STRAATNAAM_TNT
,#PLAATS = PCT_WOONPLAATS_TNT
FROM
PCTR
WHERE
PCT_POSTCODE = #POSTCODE
END
