Reading Results Into .NET

Hi. I want to write a function to retrieve all records from a "Parts" table so that I can read these records in .NET.

SqlDataReader reader = sqlCmd.ExecuteReader()

while( reader.Read() )
{
int x = reader["id"];
string partName = reader["name"];

// Do stuff with data here //
}


My question: How should the function be written?

Should I create a PROCEDURE and just call a SELECT statement?

CREATE PROCEDURE getPartsList()
AS
SELECT part_id as 'id', part_name as 'name' FROM parts


Or should I create a FUNCTION that returns a TABLE? If so, is this the correct syntax?

CREATE FUNCTION getPartsList()
RETURNS TABLE
AS
RETURN (SELECT part_id as 'id', part_name as 'name' FROM parts)


Thanks for reading
