BeginGetList and EndGetList Methods not found in 2014 R2 release

Question

Hello,

We have implemented like the below way to get the directories and files list from FTP client object.

                IAsyncResult ar = client.BeginGetList(null, null);
                while (!ar.IsCompleted)
                {
                    if (isFromObjects == false)
                    {
                        Application.DoEvents();
                    }
                    System.Threading.Thread.Sleep(1);
                }
                FtpList fileFolderList = client.EndGetList(ar);

Now we have upgraded to latest 2014 R2 version. In the latest version we are getting build errors that the BeginGetList and EndGetList methods are not found in latest 2014 R2 FTP client object.

Earlier we have copied the above code from sample application which Rebex has provided.

Please help me resolve the above issue.

Regards, Shahin.

Hello,

since release 2012R3 the old async API BeginXYZ/GetXYZ methods are not accessible under .NET 4.0 / .NET 4.5. However, you can still get access to them, just add

using Rebex.Legacy;

namespace into your program and your old code will work as before.

See more info about upgrading from 2012R2 or older.

Hello Tomas,

Actually this code I have copied from earlier version of Rebex. Can I remove these lines of code and write like below ?

FtpList list = _ftp.GetList();

If you do not need the operation to be executed in background then the normal Ftp.GetList method is suitable for you.

If we want to execute in background, what is the code I need to write in latest 2014 R2 version?

Well, if you have a working solution I guess it is really the best to add the

using Rebex.Legacy;

namespace and keep using the old style async code. Are you able to compile and run after importing the Rebex.Legacy namespace? If not please let us know.
