Question

我正在开发适用于Windows Phone 8.1的应用程序：

带有文件打开选择器的页面，可以从图库和第二页拍摄照片将该一张照片作为带有消息的电子邮件附件发送。

我如何拍摄这张照片并通过电子邮件发送。

我试图寻找一些解决方案，但到目前为止没有任何运气。

有什么建议吗？

代码是常规c#和xaml，我在Visual Studio 2015中使用Windows Phone 8.1。

您可以一步到位地使用此解决方案。

        /// <summary>
        /// Taking photo from the gallery
        /// </summary>
        private void SharePhotoClick(object sender, RoutedEventArgs e)
        {
            PhotoChooserTask ph=new PhotoChooserTask();
            ph.Completed += ph_Completed;
            ph.Show();

        }

        /// <summary>
        /// Sharing the photo to social media including email
        /// </summary>
        void ph_Completed(object sender, PhotoResult e)
        {

            ShareMediaTask smt = new ShareMediaTask();
            smt.FilePath = e.OriginalFileName;
            smt.Show();
        }

希望这有帮助！

我相信WP8.1你需要实现IContinuationManager，它将帮助你获得用户选择的图像。首先，您需要一个打开图库的活动

 private void PickAFileButton_Click(object sender, RoutedEventArgs e)
    {
        ...
        FileOpenPicker openPicker = new FileOpenPicker();
        openPicker.ViewMode = PickerViewMode.Thumbnail;
        openPicker.SuggestedStartLocation = PickerLocationId.PicturesLibrary;
        openPicker.FileTypeFilter.Add(".jpg");
        openPicker.FileTypeFilter.Add(".jpeg");
        openPicker.FileTypeFilter.Add(".png");

        // Launch file open picker and caller app is suspended
        // and may be terminated if required
        openPicker.PickSingleFileAndContinue();
    }

选择图像后，调用app.xaml.cs中的OnActivated（）方法，您需要继续管理器来获取所选文件的数据。

protected async override void OnActivated(IActivatedEventArgs args)
    {
        base.OnActivated(args);
        var continuationManager = new ContinuationManager();
        var rootFrame = CreateRootFrame();
        await RestoreStatusAsync(args.PreviousExecutionState);

        if (rootFrame.Content == null)
        {
            rootFrame.Navigate(typeof(MainPage));
        }

        var continuationEventArgs = e as IContinuationActivatedEventArgs;
        if (continuationEventArgs != null)
        {
            Frame scenarioFrame = MainPage.Current.FindName("ScenarioFrame") as Frame;
            if (scenarioFrame != null)
            {
                // Call ContinuationManager to handle continuation activation
                continuationManager.Continue(continuationEventArgs, scenarioFrame);
            }
        }

        Window.Current.Activate();
    }

现在，延续管理器将为您处理激活。

        case ActivationKind.PickSaveFileContinuation:
            var fileSavePickerPage = rootFrame.Content as IFileSavePickerContinuable;
            if (fileSavePickerPage != null)
            {
                fileSavePickerPage.ContinueFileSavePicker(args as FileSavePickerContinuationEventArgs);
            }
            break;

        case ActivationKind.PickFolderContinuation:
            var folderPickerPage = rootFrame.Content as IFolderPickerContinuable;
            if (folderPickerPage != null)
            {
                folderPickerPage.ContinueFolderPicker(args as FolderPickerContinuationEventArgs);
            }
            break;

        case ActivationKind.WebAuthenticationBrokerContinuation:
            var wabPage = rootFrame.Content as IWebAuthenticationContinuable;
            if (wabPage != null)
            {
                wabPage.ContinueWebAuthentication(args as WebAuthenticationBrokerContinuationEventArgs);
            }
            break;
    }

完成此操作后，您可以获取数据并将其保存到文件中，并将该文件附加到电子邮件中。

EmailMessage email = new EmailMessage();
email.To.Add(new EmailRecipient("test@abc.com"));
email.Subject = "Test";
var file = await GetFile();
email.Attachments.Add(new EmailAttachment(file.Name, file));
await EmailManager.ShowComposeNewEmailAsync(email);
