Я начинаю разработку. NET Я уже установил ссылки в своем проекте, которые описаны ниже.
- Oracle .DataAccess
- System.Data. OracleClient
Код такой:

private void button1_Click(object sender, EventArgs e)
{
//string oradb = "Data Source=ORCL;User Id=hr;Password=hr;";
string oradb = "DATA SOURCE=BLANK;USER ID=USER;Password=password";
OracleConnection conn = new OracleConnection(oradb); // C#
conn.Open();
OracleCommand cmd = new OracleCommand();
cmd.Connection = conn;
cmd.CommandText = "select DESCRIPTION from ncr where ncr_no ='60'";
cmd.CommandType = CommandType.Text;
OracleDataReader dr = cmd.ExecuteReader();
dr.Read();
label1.Text = dr.GetString(0);
conn.Dispose();
}
private void label1_Click(object sender, EventArgs e)
{
}
}
}

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
