Hierarichal objects to Oracle stored procedure
<p>Below is my DTO structure</p>

<pre><code>public class Config_DTO
{
    public string NAME { get; set; }
    public string TITLE { get; set; }
    public string TYP { get; set; }
    public string RMKS { get; set; }
    public string PROC { get; set; }
    public string ORGL_USER { get; set; }
    public DateTime ORGL_STAMP { get; set; }
    public string UPDT_USER { get; set; }
    public DateTime UPDT_STAMP { get; set; }
    public IEnumerable&lt;CommonConfig_DTO&gt; COLUMNS_DATATYPE { get; set; }
}

public class CommonConfig_DTO
{
    public string COLUMNS { get; set; }
    public string DATA_TYP { get; set; }
}
</code></pre>

<p>How to pass these values to a backend procedure? I have tried converting this <code>&lt;CommonConfig_DTO&gt;</code> <code>COLUMNS_DATATYPE</code> to array, but I am not successful.</p>
