Question

我在远程IBM AIX服务器上安装了Oracle 9i DB。我想使用C＃app（.Net）连接到它目前，我可以使用SQL Developer和SQLPlus从我的机器连接到它。

但是当我尝试使用System.Data.OracleClient连接Visual Studio App时。

    private static string GetConnectionString()
    {
        return "Data Source=<server address>;User ID=<username>;Password=<password>;";
    }

    // This will open the connection and query the database
    private static void ConnectAndQuery()
    {
        string connectionString = GetConnectionString();
        using (OracleConnection connection = new OracleConnection())
        {
            try
            {
                connection.ConnectionString = connectionString;
                connection.Open();
                Console.WriteLine("State: {0}", connection.State);
                Console.WriteLine("ConnectionString: {0}",
                                  connection.ConnectionString);

                OracleCommand command = connection.CreateCommand();
                string sql = "SELECT * FROM demo";
                command.CommandText = sql;

                OracleDataReader reader = command.ExecuteReader();
                while (reader.Read())
                {
                    string myField = (string)reader["f1"];
                    Console.WriteLine(myField);
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
                connection.Close();
            }
            finally
            {
                connection.Close();
            }
        }
    }

我收到以下错误：

ORA-12705指定了无效或未知的NLS参数值

我已检查NLS的注册表值，它已设置为AMERICAN_AMERICA.WE8MSWIN1252

不确定如何处理此问题。请建议
