BackgroundUploadAsync() in Windows Phone Silverlight 8.1.

Question

I have Upgraded my Windows Phone 8.0 App to WP SL 8.1

Iam getting an error like as below 

The best overloaded method match for 'Microsoft.Live.LiveConnectClient.BackgroundUploadAsync(string, string, Windows.Storage.IStorageFile,Microsoft.Live.OverwriteOption)' has some invalid arguments.

I wrote the code like this

public void updatefile(string folderid, string foldername)
        {
            try
            {
                Dictionary<string, IRandomAccessStream> stream = GetFiles(foldername);
                foreach (KeyValuePair<string, IRandomAccessStream> strm in stream)
                {
                    //string a = Convert.ToString(strm);
                    LiveConnectClient fileclient = new LiveConnectClient(session);
                   fileclient.BackgroundUploadAsync(folderid, strm.Key.ToString(), strm.Value.AsStreamForRead(), OverwriteOption.Overwrite);
                }
            }
            catch (Exception ex)
            {
                checktime = true;
                AppSettings.BackgroundAgentStatus = SyncAgentStatus.DownloadFavourites;
                Exceptions.SaveOrSendExceptions("Exception in updatefile Method In UploadStory.cs file", ex);
            }
        }

And the Definition for BackgroundUploadAsync() is like 

public Task<LiveOperationResult> BackgroundUploadAsync(string path, string fileName, IInputStream inputStream, OverwriteOption option);
        public Task<LiveOperationResult> BackgroundUploadAsync(string path, string fileName, IStorageFile inputFile, OverwriteOption option);
        public Task<LiveOperationResult> BackgroundUploadAsync(string path, string fileName, IInputStream inputStream, OverwriteOption option, CancellationToken ct, IProgress<LiveOperationProgress> progress);
        public Task<LiveOperationResult> BackgroundUploadAsync(string path, string fileName, IStorageFile inputFile, OverwriteOption option, CancellationToken ct, IProgress<LiveOperationProgress> progress);

Help me in getting out from this..!!!!!

Answer 1

The documentation says these are the available API for Windows Phone:

BackgroundUploadAsync(String, Uri, OverwriteOption)
BackgroundUploadAsync(String, Uri, OverwriteOption, String)

The API you tried to use is for Windows PC. Was this code working in Windows Phone 8?

Answer 2

This code is working on Windows Phone 8 but with a small change inplace of BackGroundUploadAsync() we used UploadAsync().

Iam using LiveSDK 5.6

I think error is with the conversion from "cannot convert from 'System.IO.Stream' to Windows.Storage.IStorageFile" 

cannot convert from 'System.IO.Stream' to 'Windows.Storage.Streams.IInputStream'

how to do this conversions.?

Answer 4

With the change of BackGroundUploadAsync() to UploadAsync ..

It is working on Windows Phone 8

but when comming to silverlight wp 8.1 there is no UploadAsync, So i replaced it with BackGroundUploadAsync()

here it is not working,..

Giving Errors like 

Error 116 Argument 3: cannot convert from 'System.IO.Stream' to 'Windows.Storage.IStorageFile'

Error 121 Argument 3: cannot convert from 'System.IO.Stream' to 'Windows.Storage.Streams.IInputStream'

I had Modified the above code as like this, It Worked for me on WP SL 8.1

   public void updatefile(string folderid, string foldername)
        {
            try
            {
                Dictionary<string, IRandomAccessStream> stream = GetFiles(foldername);
                foreach (KeyValuePair<string, IRandomAccessStream> strm in stream)
                {
                    //string a = Convert.ToString(strm);
                    LiveConnectClient fileclient = new LiveConnectClient(session);
                    string conv = strm.Key.ToString();
                    IInputStream strem = strm.Value.GetInputStreamAt(0);
                    fileclient.BackgroundUploadAsync(folderid, conv, strem, OverwriteOption.Overwrite);
                }
            }
            catch (Exception ex)
            {
                checktime = true;
                AppSettings.BackgroundAgentStatus = SyncAgentStatus.DownloadFavourites;
                Exceptions.SaveOrSendExceptions("Exception in updatefile Method In UploadStory.cs file", ex);
            }
        }
