I have a C# WinForms application that manages stored procedures used by different services. What the users see is something like that:

exec stored_procedure_name param1, param2, param3

And since param1 doesn't mean anything to them (they can't see the stored procedure), I would like to present to them small descriptions of the parameters which are normally saved in the header of the stored procedure.

A typical stored procedure would like:

IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[stored_procedure_name]') AND type in (N'P', N'PC'))
DROP PROCEDURE [dbo].[stored_procedure_name]
GO

SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

/*************************************************************************************
[Procedure Info]
Author = myName
Description = this stored procedure returns results.

**************************************************************************************
[Parameters Info]
@param1 = this is parameter one
@param2 = this is parameter two
@param3 = this is parameter three

**************************************************************************************

*/

CREATE PROCEDURE [dbo].[stored_procedure_name]
@param1 int,
@param2 nvarchar(20),
@param3 nvarchar(10)
AS
BEGIN
    -- SP code here
END
GO

From the above, I want to get the descriptions in the Parameters info. I know that I can use the following SQL to retrieve the stored procedure as text/table:

CREATE TABLE #tmpHeader
(
   TEXT NVARCHAR(1000)
)

INSERT INTO #tmpHeader
EXEC sp_helptext 'stored_procedure_name';

SELECT * FROM #tmpHeader

DROP TABLE #tmpHeader

Any ideas or suggestions how to proceed from here in order to get the content of the parameters info? I am also open to any other suggestions.
