创建C#控制台项目.首先引用system.oracle.dll,然后在类文件中键入如下代码:

using System;
using System.Collections.Generic;
using System.Text;
using System.Data;
using System.Data.OracleClient;

namespace ConnectOracle
{
    class Program
    {
        static void Main(string[] args)
        {

            //server=数据库Sid的名字
            OracleConnection con = new OracleConnection("server=student;user

id=scott;password=tiger");
            //OracleDataAdapter da = new OracleDataAdapter("select * from demo",con);

            //demo是oracle数据库中的表名
            OracleCommand com = new OracleCommand("select * from demo",con);
            con.Open();
            OracleDataReader dr = com.ExecuteReader();
            while (dr.Read())
            {
                Console.WriteLine(dr[0]);
                Console.WriteLine(dr.GetValue(1).ToString());
            }
            dr.Close();
            con.Close();

        }
    }
}
