2005調用存儲過程

調用無參數的存儲過程可以這樣寫。
  SqlDataSource ds = new SqlDataSource();
            ds.ConnectionString = "Data Source=(local);Initial Catalog=E_Quotation;User ID=sa;Password=breakin";
            ds.SelectCommand = "quote_fit_home";
            ds.SelectCommandType = SqlDataSourceCommandType.StoredProcedure ;
            this.GridView1.DataSource = ds;
            this.GridView1.DataBind();

如果要引入參數的話該怎麼寫？
