C# dropbox SDK listfoldercontinueasync(string cursor) not working

I'll be happy to help with any issues you're having with the Dropbox API, but I'll need some more information. Please reply with:

• the version number of the platform and SDK/library you are using, if any
• the steps to reproduce the issue, including relevant code snippet(s), but don't include any access/refresh token(s)
• the full text of any error or unexpected output

-using dropbox.net SDK

-CodeSnippet
var listfoldercontinuearg = new ListFolderContinueArg(cursor);
var listFolderResult = dropboxClient.Files.ListFolderContinueAsync(listfoldercontinuearg).Result;

using ablove code snippet, able to fetch chenges made on the home location (ie.:\\home).
but not able to fetch changes which are made on subfolder(ie.:\\home\subfolder)

var listfoldercontinuearg = new ListFolderContinueArg(previousDeltaLink);

listFolderResult = dropboxClient.Files.ListFolderContinueAsync(listfoldercontinuearg).Result;

ProcessLogger.Info($"Processing {listFolderResult.Entries.Count} items..");

foreach (var entry in listFolderResult.Entries)
{}

this is my exact code can you tell where do i need to set ListFolderArg.recursive to true

i am calling first time ListFolderAsync here 

ListFolderResult listFolderResult;

listFolderResult = dropboxClient.Files.ListFolderAsync(controlpath, true, false, false, false, true, 200).Result;

and i have here setted isrecursive to true still not getting results 

I see you've also posted this in a new thread, so I'll follow up with you there.

For future reference, please note it is not necessary to post the same question in multiple threads.
