Question

I try to upload a text file to my skydrive or at least create new text file in SD and edit it’s content, through SkyDrive API in my Windows 8 application.
How can I do that?

I tried to do something like that:

        LiveConnectClient client = new LiveConnectClient(session);
        var fileData = new Dictionary<string, object>();
        fileData.Add("name", "new_file.txt");
        try
        {
            LiveOperationResult fileOperationResult = await client.PutAsync("me/skydrive", fileData);
            this.infoTextBlock.Text = fileOperationResult.ToString();
        }
        catch (LiveConnectException exception)
        {
            this.infoTextBlock.Text = exception.Message;
        }

but I get error
“The provided request is not valid. The root SkyDrive folder cannot be updated.”
If I write something like “me/skydrive/” I get
“The provided URL is not valid. The requested path ” is not supported”.
Method LiveConnectClient.PutAsync allows me only to update existing properties (but not it’s content).

How it should be done properly?

Btw – Is content on LCDC(http://msdn.microsoft.com/en-us/library/live/hh826531.aspx) updated? I’m asking because some methods, which are in documentation, doesn’t exist in dlls (f.e. LiveConnectClient.Upload. There’s only BackgroundUploadAsync).

Thanks for help in advance,

Answer 1

Close but as I wrote: I can’t use client.upload method because LiveConnectClient class doesn’t contain it. That’s why I asked about site content update.

Anyway – I’ve got an answer:

//create a StorageFile (here is one way to do that if it is stored in your ApplicationData)
StorageFile file = awaitApplicationData.Current.LocalFolder.GetFileAsync("yourfilename.txt");

try {
   client = new LiveConnectClient(session);
   LiveOperationResult operationResult = await client.BackgroundUploadAsync("me/skydrive", file.Name, file, OverwriteOption.Overwrite);
}
catch (LiveConnectException exception) {
  //handle exception                
}
