c#访问oracle数据库

想在c#中访问oracle数据库，毕竟是开发，想要轻量级访问oracle，客户机上无需安装oracle环境就能正常运行程序。

在网上找了相关资料，只需要引用一个dll即可实现。

访问代码(需引用dll):

public class OracleConfig
    {
        //string connString = "Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=ip)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=ORCL)));Persist Security Info=True;User ID=system;Password=password;";
public string host { get; set; }

        public string port { get; set; }

        public string service { get; set; }

        public string id { get; set; }

        public string password { get; set; }
    }

public class OracleHelper
    {
        OracleConfig oracleConfig;
        OracleConnection oracleConnection;
        OracleDataReader oracleDataReader;
        OracleCommand oracleCommand;
        public OracleHelper(OracleConfig oracleConfig)
        {
            this.oracleConfig = oracleConfig;
        }
        public OracleDataReader GetDataReader(string commandText)
        {
            GetOracleConnection(oracleConfig);
            oracleCommand = oracleConnection.CreateCommand();
            oracleCommand.CommandText = commandText;
            oracleDataReader = oracleCommand.ExecuteReader();
            return oracleDataReader;
        }

        public void CloseConnection()
        {
            oracleDataReader.Close();
            oracleDataReader.Dispose();
            oracleCommand.Dispose();
            oracleConnection.Close();
            oracleConnection.Dispose();
        }

        private void GetOracleConnection(OracleConfig oracleConfig)
        {
            oracleConnection = new OracleConnection();
            oracleConnection.ConnectionString = string.Format("Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST={0})(PORT={1}))(CONNECT_DATA=(SERVICE_NAME={2})));Persist Security Info=True;User ID={3};Password={4};", oracleConfig.host,oracleConfig.port,oracleConfig.service,oracleConfig.id,oracleConfig.password);
            oracleConnection.Open();

        }
    }

OracleDataReader oracleDataReader = oracleHelper.GetDataReader("select * from table");

                    while (oracleDataReader.Read())
                    {
                       Console.WriteLine(oracleDataReader["字段"].ToString());
}
oracleHelper.CloseConnection();
