StringBuilder result = new StringBuilder( ); // Get the HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\ODBC Drivers key. RegistryKey keyLocalMachine = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\ODBC\ODBCINST.INI\ODBC Drivers", false); string[] valueNames = keyLocalMachine.GetValueNames( ); for(int i = 0; i < valueNames.Length; i++) result.Append(valueNames[i] + Environment.NewLine); resultTextBox.Text = result.ToString( ); Discussion The .NET Framework classes that manipulate the registry are found in the
