Calling Business Central SOAP Web Service using .NET

Posted on by 170

Hi Everyone,

I am trying to call Business Central SOAP web service using the .NET code. i am able to do it with Business Central 15 online. However, it is not working with BC 16 online. 

URL is working fine with browser or SOAP UI, but, while accessing it using the .NET code, it is giving below error.

Connection to Business Central Failed System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

Below is my piece of code for reference.

updatebacktoeventrecord.Url = str;

updatebacktoeventrecord.UseDefaultCredentials = false;
updatebacktoeventrecord.Credentials = new System.Net.NetworkCredential(txtBCWebUser.Text, txtBCWebServiceKey.Password.ToString()); 
NAVConnector_Service service = new NAVConnector_Service();

if (updatebacktoeventrecord.WebServicesRunning() == 0)  //Error occurred here. WebServicesRunning is a procedure in Codeunit published as Web Service.
{
lbl_Error_Information.Visibility = System.Windows.Visibility.Visible;
lbl_Error_Information.Content = resourceDictionary["Conn50"].ToString();
lbl_Error_Information.Background = brush;
lblBaseServiceName.Content = "";
if (Directory.Exists(logpath))
{
WriteToFile("Connection to Business Central Failed due to web service setup in Business Central ", logpath.ToString());
}
return false;
}
else
{
if (Directory.Exists(logpath)) { WriteToFile("Connection to Business Central Succeeded ", logpath.ToString()); }
return true;
}

could anyone suggest what is the issue?? same code is working with Business Central 15.

Thanks in Advance.

    Hi Sunil,

    This can be caused by a timeout. In any case, I would recommend opening a support ticket with Microsoft via your Solution Provider or Business Central Partner. 

    Hope that helps.
