无法从Windows Phone 8应用程序上传文件 [英] Unable to upload file from a Windows Phone 8 app

问题描述

我正在尝试将一个位于MemoryStream中的GPX文件上传到SkyDrive。以下是相关代码：

 //开始上传过程。首先检查我们在Skydrive中是否有足够的空间... 
 LiveConnectClient客户端=新的LiveConnectClient（App.Client.Session）; 
 if（client！= null）
 {
 LiveOperationResult quotaResult = await client.GetAsync（" me / skydrive / quota"）; 
 if（quotaResult.Result.ContainsKey（" available"））
 {
 Int64 available = Convert.ToInt64（quotaResult.Result [" available"]）; 
 if（可用> = memStream.Length）
 {
尝试
 {
 LiveOperationResult uploadResult = await client.UploadAsync（" me / skydrive"，fileName， memStream，OverwriteOption.Rename）; 
 ProgressIndicatorIsVisible = false; 
} 
 catch（例外e）
 {
 DialogMessage message = new DialogMessage（e.Message，DialogMessageCallback）; 
} 
} 
 else 
 {
 DialogMessage message = new DialogMessage（AppResources.SkydriveFull，DialogMessageCallback）; 
 Messenger.Default.Send< DialogMessage>（消息）; 
} 
} 
} 

我遇到的问题是它似乎等待了一段时间，然后抛出以下异常在client.UploadAsync（）行：

client_error：Microsoft.Live.LiveConnectException：抛出了类型'Microsoft.Live.LiveConnectException'的异常。

这是在手机上运行（我的电脑无法运行模拟器），无论手机是连接到WiFi还是移动数据，都会出现。

我做错了什么？

解决方案

异常中是否还有其他信息 - 消息，堆栈跟踪等。 ？

I'm trying to upload a GPX file, which is in a MemoryStream, to SkyDrive. Here's the relevant code :

// Start the upload process. First check we have enough space in the Skydrive...
                LiveConnectClient client = new LiveConnectClient(App.Client.Session);
                if (client != null)
                {
                    LiveOperationResult quotaResult = await client.GetAsync("me/skydrive/quota");
                    if (quotaResult.Result.ContainsKey("available"))
                    {
                        Int64 available = Convert.ToInt64(quotaResult.Result["available"]);
                        if (available >= memStream.Length)
                        {
                            try
                            {
                                LiveOperationResult uploadResult = await client.UploadAsync("me/skydrive", fileName, memStream, OverwriteOption.Rename);
                                ProgressIndicatorIsVisible = false;
                            }
                            catch (Exception e)
                            {
                                DialogMessage message = new DialogMessage(e.Message, DialogMessageCallback);
                            }
                        }
                        else
                        {
                            DialogMessage message = new DialogMessage(AppResources.SkydriveFull, DialogMessageCallback);
                            Messenger.Default.Send<DialogMessage>(message);
                        }
                    }
                }

The problem I'm having is that it seems to wait for a while, then throw the following exception on the client.UploadAsync() line:

client_error: Microsoft.Live.LiveConnectException: Exception of type 'Microsoft.Live.LiveConnectException' was thrown.

This is being run on a phone (my computer won't run the emulator), and occurs whether the phone is connected to WiFi or mobile data. 

What am I doing wrong?

解决方案

Is there any more information in the exception - message, stack trace, etc.?
