ASP.NET中调用存储过程

public static string GetCustomerCName(ref ArrayList arrayCName,ref ArrayList arrayID)
        {
            SqlConnection con=ADConnection.createConnection();
            SqlCommand cmd=new SqlCommand("testProcedure_AX",con);
            cmd.CommandType=CommandType.StoredProcedure;
            con.Open();
            try
            {
                SqlDataReader dr=cmd.ExecuteReader();
                while(dr.Read())
                {
                    if(dr[0].ToString()=="")
                    {
                        arrayCName.Add(dr[1].ToString());
                    }
                }
                con.Close();
                return "OK!";
            }
            catch(Exception ex)
            {
                con.Close();
                return ex.ToString();
            }
        }
注:其實就是把以前SqlCommand cmd=new SqlCommand("select userID from USERS order by userid desc",con);
中的SQL語句替換為存儲過程名,再把cmd的類型標注為CommandType.StoredProcedure(存儲過程)

CREATE PROCEDURE dbo.AXzhz
/*這里輸注釋*/
@startDate varchar(16),
@endDate varchar(16)
AS
 select id  from table_AX where commentDateTime>@startDate and commentDateTime<@endDate order by contentownerid DESC

注:@startDate varchar(16)是聲明@startDate 這個變量,多個變量名之間用【,】隔開.后面的SQL就可以使用這個變量了.

我怎麼在ASP.NET中調用這個參數的存儲過程?

 public static string GetCustomerCNameCount(string startDate,string endDate,ref DataSet ds)
{
            SqlConnection con=ADConnection.createConnection();
//-----------------------注意這一段------------------------------------------
            SqlDataAdapter da=new SqlDataAdapter("AXzhz",con);
            para0=new SqlParameter("@startDate",startDate);
            para1=new SqlParameter("@endDate",endDate);
            da.SelectCommand.Parameters.Add(para0);
            da.SelectCommand.Parameters.Add(para1);
            da.SelectCommand.CommandType=CommandType.StoredProcedure;
//----------------------------------------------------------------------------
            try
            {
                con.Open();
                da.Fill(ds);
                con.Close();
                return "OK";
            }
            catch(Exception ex)
            {
                return ex.ToString();
            }           
        }
