Crystal Report in C#, Stored Procedure

Crystal report in C# , stored procedure
Dear Friends,
I want to create a Crystal report in C# using Parameterised Storred Procedure
This is my Stored Procedure
CREATE PROCEDURE sp_percentageGraph
(
@RecordNo INT,
@startDate varchar(40),
@endDate varchar(40)
)
AS
BEGIN
select PlugPercentage,TimeInspected from statistic where RecordNo =
@RecordNo and TimeIninterval between(@startDate) and (@endDate)
return
END
GO

I passed 3 input parametrs.
How to use this storedprocedure to my C# program and pass the parameters to
the crystal report.
The user would change the timeinterval and recordNo. According to change the
timeinverval and Recordno we want my report
I am new to this.
If any one knows please let me know....if sample C#, Storedprocedure source
code would be greatly appreciate.

Thanks
Ever Smiling
