連接Oracle數據庫

之前我也有談論過.net中對不同數據庫的連接操作，這次單談談Oracle，其實你要連接到Oracle數據庫是要要求有個Oracle.DataAccess.dll。可以到Oracle網站下載。如果你安裝了Oracle了，也會有這個dll了。引入就OK
因為是測試，學習。所以代碼也簡單。
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using Oracle.DataAccess.Client;
using System.Windows.Forms;
namespace OraWinApp
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
string oradb = "Data Source=(DESCRIPTION=" + "(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=10.1.3.14)(PORT=1521)))" + "(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=lab)));" + "User Id=adte;Password=adte123;";
OracleConnection conn = new OracleConnection(oradb);
try
{
conn.Open();
string sql = "select * from TB_ZCTYPE";
OracleCommand cmd = new OracleCommand(sql, conn);
cmd.CommandType = CommandType.Text;
OracleDataAdapter oda = new OracleDataAdapter();
oda.SelectCommand = cmd;
DataSet ds = new DataSet();
oda.Fill(ds);
dataGridView1.DataSource = ds.Tables[0].DefaultView;

}
catch (Exception ex) // catches any error
{
MessageBox.Show(ex.Message.ToString());
}
finally
{
conn.Close();
}
}
}
}

其實很多都是跟sql是一樣的模式。我也是學Ň
