1、添加 Oracle.ManagedDataAccess.dll
2、连接Oracle的实例得添加到Oracle的监听器中，不然会报“ORA-12514: TNS: 监听程序当前无法识别连接描述符中请求的服务”的错，添加如下，本例使用的是Oracle10g，找到C:\oracle\product\10.2.0\db_1\NETWORK\ADMIN下的lisener.org，打开后修改添加标红的部分
# listener.ora Network Configuration File: C:\oracle\product\10.2.0\db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = C:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = ORCL)
(ORACLE_HOME = C:\oracle\product\10.2.0\db_1)
(SID_NAME = ORCL)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.121.130)(PORT = 1521))
)
)
3、连接字符串：
string connStr = "Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.121.130)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=ORCL)));Persist Security Info=True;User ID=scott;Password=tiger;";
其中Oracle数据库服务器IP：192.168.121.130
ServiceName：ORCL
用户名：scott
密码：tiger
4、查看Oracle的实例名，用sys作为dba登录，执行语句 select name from v$database;
5，C#代码
using System;
using System.Collections.Generic;
using System.Configuration;
using Oracle.ManagedDataAccess.Client;
using System.Linq;
using System.Text;
namespace ADOSample
{
class Program
{
static void Main(string[] args)
{
string connStr = "Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.121.130)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=ORCL)));Persist Security Info=True;User ID=scott;Password=tiger;";
using (OracleConnection conn = new OracleConnection(connStr))
{
string sql = "select * from dept ";
conn.Open();
using (OracleCommand cmd = new OracleCommand(sql, conn))
{
using (OracleDataReader dataReader = cmd.ExecuteReader())
{
while (dataReader.Read())
{
string obj = (string)dataReader[1];
Console.WriteLine(obj);
}
}
}
}
Console.ReadKey();
}
}
}
