c# – Downloading design step attachments from HP ALM

I used to be utilizing under code to obtain attachments for take a look at instances on the HP ALM TestLab folder,
However then I discover out that attachments could be obtainable on the step degree too.
So is there any technique to obtain attachments for take a look at steps?

I attempted with altering 2nd line to

TDAPIOLELib.StepFactory tsTestFact = tDConnection.StepFactory;

But it surely was not working.

public void DownloadTestAttachments_FromVB_TestLab()

        {

            String AttachmentDownloadPath = @"C:temp";

            TDAPIOLELib.TSTestFactory tsTestFact = tDConnection.TSTestFactory;

            TDAPIOLELib.Checklist tsTestList = tsTestFact.NewList("");

            TDAPIOLELib.AttachmentFactory attFact;

            TDAPIOLELib.Checklist attList;

            Console.WriteLine("Downloading attachments for the Exams : " + AttachmentDownloadPath);

            strive

            {

                foreach (TDAPIOLELib.TSTest tsItem in tsTestList)

                {

                    if (tsItem.HasAttachment == true)

                    {

                        attFact = tsItem.Attachments;

                        attList = attFact.NewList("");

                        foreach (TDAPIOLELib.Attachment attItem in attList)

                        {

                            attItem.Load(true, AttachmentDownloadPath + "" + attItem.Title);

                        }

                    }

                }

            }

            catch (Exception x)

            {

                Console.WriteLine(x.ToString());

            }

        }
