WEB.config:
  <connectionStrings>
    <add name="conn" connectionString="Data Source=orcl;User ID=qxw;Password=123456" providerName="System.Data.OracleClient"/>
  </connectionStrings>
数据库类：DBTool.cs:
    public class DBTool
    {

        public OracleConnection GetConnection()
        {
            string str = ConfigurationManager.ConnectionStrings["conn"].ConnectionString;
            OracleConnection conn = new OracleConnection(str);
            return conn;
        }


        public DataTable Get_FFLOWList()
        {
            string sql = "select * from rr";
            OracleConnection conn = GetConnection();
            OracleDataAdapter oda = new OracleDataAdapter(sql, conn);
            DataTable dt = new DataTable();
            oda.Fill(dt);
            return dt;
        }

    }

        protected void Page_Load(object sender, EventArgs e)
        {
            DBTool tool = new DBTool();
            DataTable dt = tool.Get_FFLOWList();

            GridView1.DataSource = dt;
            GridView1.DataBind();



            DataList1.DataSource = dt;
            DataList1.DataBind();

            Repeater1.DataSource = dt;
            Repeater1.DataBind();
        }
