Good afternoon.


I'm very beginner


After migrating from mysql 5.1 to mysql 5.7 my tool that transfers data from one database to another has stopped working.




It generates this error in the log.

HelpLink:
InnerException:
Message: Value cannot be null.
Parameter name: s
Source: mscorlib
StackTrace: at System.IO.StringReader..ctor(String s)
at System.Xml.XmlDocument.LoadXml(String xml)
at IntegracaoGhost.Service.ImportIcab.AccessXML.loadXml(String xml)

at IntegracaoGhost.Service.ImportIcab.Task.InsertCliente()
at IntegracaoGhost.Service.ImportIcab.Task.Insert()
at IntegracaoGhost.Service.ImportIcab.Task..ctor()
TargetSite: Void .ctor(System.String)


Follows the code


using CGP.Library.DataAccesLayer;


namespace IntegracaoGhost.IcabModel
{
public class Context : ContextBase
{
internal ConnectionInfo IcabConnectionInfo => GetConnectionInfo(Provider.MySql);


public string Name { get; set; }


static Context _instanc = null;
public static Context Instanc
{
get
{
if (_instanc == null)
_instanc = new Context();


_instanc.Initialize(_instanc.IcabConnectionInfo);


return _instanc;
}


set
{
_instanc = value;
//_instanc = null;
}
}


Companies _company = null;
public Companies Company => _company ?? (_company = new Companies());


Drivers _driver = null;
public Drivers Driver => _driver ?? (_driver = new Drivers());


Vehicles _vehicle = null;
public Vehicles Vehicle => _vehicle ?? (_vehicle = new Vehicles());


Customers _customer = null;
public Customers Customer => _customer ?? (_customer = new Customers());


CustomerPasswords _customerPassword = null;
public CustomerPasswords CustomerPassword => _customerPassword ?? (_customerPassword = new CustomerPasswords());


LoyaltyCards _loyaltyCard = null;
public LoyaltyCards LoyaltyCard => _loyaltyCard ?? (_loyaltyCard = new LoyaltyCards());


Capabilities _capabilities = null;
public Capabilities Capabilities => _capabilities ?? (_capabilities = new Capabilities());
}
}
