I have created a web service and a function in it that should return a list of 11thousand records retreived from a pervasive database

Here is my function in the web service.

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
public class BBI : System.Web.Services.WebService
{
    [WebMethod]
    public List<myObject> getAll()
    {
        List<myObject> result = new List<myObject>();
        PsqlConnection conn = new PsqlConnection("Host=soemthing;Port=something;Database=something;Encoding=IBM861");
        conn.Open();
        string strSql = "select 0, 1, 2, 3, 4, 5 from something";
        PsqlCommand DBCmd = new PsqlCommand(strSql, conn);
        PsqlDataReader myDataReader;
        myDataReader = DBCmd.ExecuteReader();
        while (myDataReader.Read())
        {
            myObject b = new myObject();
            b.0 = Convert.ToInt32(myDataReader[0].ToString());
            b.1 = myDataReader[1].ToString();
            b.2 = myDataReader[2].ToString();
            b.3 = myDataReader[3].ToString();
            b.4 = myDataReader[4].ToString();
            b.5 = myDataReader[5].ToString();
            result.Add(b); 
        }
        conn.Close();
        myDataReader.Close();
        return result;
    }
}

Then i add web reference to this web service in my client program and call the reference BBI. Then i call to the getAll function and get the error : There is an error in XML document (1, 63432).

public List<BBI.myObject> getAll()
{
    BBI.BBI bbi = new BBI.BBI();

    List<BBI.myObject> allBooks = bbi.getAll().OfType<BBI.myObject>().ToList(); 
    return allBooks;
}

Here is the total exception detail
