ASP.Net(C#)串連Oracle資料庫的方法

using System.Data.OracleClient;
using System.Data;

//在表單上添加一個按鈕，叫Button1，雙擊Button1，輸入以下代碼
private void Button1_Click(object sender, System.EventArgs e)
        {
             string ConnectionString="Data Source=sky;user=system;password=manager;";                //寫串連串
             OracleConnection conn=new OracleConnection(ConnectionString);                //建立一個新串連
             try
             {
                conn.Open();
                OracleCommand cmd=conn.CreateCommand();

                cmd.CommandText="select * from MyTable";                //在這兒寫sql語句
                OracleDataReader odr=cmd.ExecuteReader();                //建立一個OracleDateReader對象
                while(odr.Read())                //讀取資料，如果odr.Read()返回為false的話，就說明到記錄集的尾部了  

            
                {
                     Response.Write(odr.GetOracleString(1).ToString());                //輸出欄位1，這個數是欄位索引

，具體怎麼使用欄位名還有待研究
                }
                odr.Close();
             }
             catch(Exception ee)
             {
                Response.Write(ee.Message);                //如果有錯誤，輸出錯誤資訊
             }
             finally
             {
                conn.Close();                //關閉串連
             }
        }
