关于ASP.NET2.0编写扩展存储过程的问题

SqlPipe 类
C#  复制代码
[Microsoft.SqlServer.Server.SqlProcedure()]
public static void StoredProcExecuteCommand(int rating)
{
    // Connect through the context connection.
    using (SqlConnection connection = new SqlConnection("context connection=true"))
    {
        connection.Open();

        SqlCommand command = new SqlCommand(
            "SELECT VendorID, AccountNumber, Name FROM Purchasing.Vendor " +
            "WHERE CreditRating <= @rating", connection);
        command.Parameters.AddWithValue("@rating", rating);

        // Execute the command and send the results directly to the client.
        SqlContext.Pipe.ExecuteAndSend(command);
       
    }
以上存储过程的执行结果怎么样在ASP.NET2.0应用程序端来调用？
如果想把以上存储过程的返回结果体现在DataList控件中，应用程序端的调用代码是什么样的？
