[导入]ASP.Net(C#)连接Oracle数据库的方法

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

//在窗体上添加一个按钮，叫Button1，双击Button1，输入以下代码 private void Button1_Click(object sender, System.EventArgs e)         {              string ConnectionString="Data Source=sky;user=system;password=manager;";                //写连接串              OracleConnection conn=new OracleConnection(ConnectionString);                //创建一个新连接              try              {                 conn.Open();                 OracleCommand cmd=conn.CreateCommand();

                cmd.CommandText="select * from MyTable";                //在这儿写sql语句                 OracleDataReader odr=cmd.ExecuteReader();                //创建一个OracleDateReader对象                 while(odr.Read())                //读取数据，如果odr.Read()返回为false的话，就说明到记录集的尾部了  

                             {                      Response.Write(odr.GetOracleString(1).ToString());                //输出字段1，这个数是字段索引

，具体怎么使用字段名还有待研究                 }                 odr.Close();              }              catch(Exception ee)              {                 Response.Write(ee.Message);                //如果有错误，输出错误信息              }              finally              {                 conn.Close();                //关闭连接              }         }
