Warnings are reported using TdConnection.InfoMessage event.

public TdConnection OpenConnection(String connectionString)
{
    try
    {
        TdConnection cn = new TdConnection(connectionString);
        cn.Open();
        
        return cn;
    }
    catch(TdException e)
    {
        for (int index = 0; index < e.Errors.Count; index++)
        {
            Console.WriteLine(“ERROR: {0} ({1})”, e.Errors[index].Message, 
                                                  e.Errors[index].Number);
