In the code behind: MainPage.xaml.cs,

Update your code with this:

  1. using System;
  2. using System.Collections.Generic;
  3. using System.IO;
  4. using System.Linq;
  5. using System.Runtime.InteropServices.WindowsRuntime;
  6. using Windows.ApplicationModel.DataTransfer;
  7. using Windows.Foundation;
  8. using Windows.Foundation.Collections;
  9. using Windows.UI.Xaml;
  10. using Windows.UI.Xaml.Controls;
  11. using Windows.UI.Xaml.Controls.Primitives;
  12. using Windows.UI.Xaml.Data;
  13. using Windows.UI.Xaml.Input;
  14. using Windows.UI.Xaml.Media;
  15. using Windows.UI.Xaml.Navigation;
  17. namespace ShareAttachment
  18. {
  19. public sealed partial class MainPage : Page
  20. {
  21. public MainPage()
  22. {
  23. this.InitializeComponent();
  24. var dtm = Windows.ApplicationModel.DataTransfer.DataTransferManager.GetForCurrentView();
  25. dtm.DataRequested += Dtm_DataRequested;
  26. }
  28. private async void Dtm_DataRequested(Windows.ApplicationModel.DataTransfer.DataTransferManager sender, Windows.ApplicationModel.DataTransfer.DataRequestedEventArgs args)
  29. {
  30. DataPackage dataToShare = args.Request.Data;
  31. dataToShare.Properties.Title = "Attachment Sharing Application";
  32. dataToShare.Properties.Description = "Attachment Sharing Application that share images";
  34. var storageFile = await Windows.ApplicationModel.Package.Current.InstalledLocation.GetFileAsync("Assets\\abc.jpg");
  35. var imageStream = Windows.Storage.Streams.RandomAccessStreamReference.CreateFromFile(storageFile);
  36. dataToShare.SetBitmap(imageStream);
  37. }
  39. private void btn_Share_Click(object sender, RoutedEventArgs e)
  40. {
  41. Windows.ApplicationModel.DataTransfer.DataTransferManager.ShowShareUI();
  42. }
  43. }
  44. }
Step 5:
