how to call stored procedure in c#

Step 1) Create a ASP.NET Web Application using .net 4.0

before that

create database table called "sales data" 

USE [test]
GO

/****** Object:  Table [dbo].[Sales Data]    Script Date: 05/15/2012 00:40:34 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[Sales Data](
[ID] [int] IDENTITY(1,1) NOT NULL,
[Sales Man] [nchar](20) NOT NULL,
[2005] [int] NOT NULL,
[2006] [int] NOT NULL,
[2007] [int] NOT NULL,
 CONSTRAINT [PK_Sales Data] PRIMARY KEY CLUSTERED 
(
[ID] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

INSET DATA INTO TABLE

INSERT INTO [Sales Data]([Sales Man],[2005],[2006],[2007]) VALUES('CAROL',2000,3000,4000)
......

create stored procedure 

USE [test]
GO

/****** Object:  StoredProcedure [dbo].[getsalesdata]    Script Date: 05/15/2012 00:42:26 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
