C#利用ODP.net连接Oracle数据库的操作方法

复制代码 代码如下:

数据库SID =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = Oracle主机名或者IP)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = 数据库SID)
)
)

复制代码 代码如下:

OracleConnection conn =
new OracleConnection();
try
{
conn.ConnectionString = ConfigurationManager.ConnectionStrings["oradb"].ConnectionString;
conn.Open();
string sql = " select id,content from test"; // C#
OracleCommand cmd = new OracleCommand(sql, conn);
cmd.CommandType = CommandType.Text;
OracleDataReader dr = cmd.ExecuteReader(); // C#
List<string> contents = newList<string>();
while(dr.Read())
{
contents.Add(dr["content"].ToString());
}
listBox1.ItemsSource = contents;
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}
finally
{
conn.Clone();
}

复制代码 代码如下:

<connectionStrings >
<addconnectionString="Data Source=(DESCRIPTION=
(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.1.1)(PORT=1521)))
(CONNECT_DATA=(SERVICE_NAME=****)));
User Id=***;Password=***;"/>
</connectionStrings>
