.net 不安装客户端连接oracle

 

Oralce版本：11g R2

1、将oci.dll、ociw32.dll、Oracle.DataAccess.dll、orannzsbb11.dll、oraocci11.dll、oraociicus11.dll、OraOps11w.dll拷到bin目录下
2、添加对Oracle.DataAccess.dll的引用
3、编写代码，如：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Oracle.DataAccess.Client;

namespace Oracle1
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            string connstring = "Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.0.37)(PORT=1521))" +"(CONNECT_DATA=(SID=orcl)));User Id=system;Password=ikmbikmb;";

            using (OracleConnection conn = new OracleConnection(connstring))
            {

                conn.Open();

                string sql = "select * from t1 t";

                using (OracleCommand comm = new OracleCommand(sql, conn))
                {

                    using (OracleDataReader rdr = comm.ExecuteReader())
                    {

                        while (rdr.Read())
                        {
                            Response.Write(rdr.GetString(1) + "<br>");

                        }

                    }

                }

            }

        }
    }
}
