There is an error in XML document... When calling to web service
- by Sigurjón Guðbergsson
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
