FilePicker UWP

Hi,
In my Game I can't open the NativeFile picker. I created a seperate Visual Studio project and followed this tutorial. The main code to open the FilePicker is:

Code (CSharp):

1. #if NETFX_CORE
2.         public async void OpenFilePicker()
3.         {
4.             var picker = new Windows.Storage.Pickers.FileOpenPicker();
5.             picker.ViewMode = Windows.Storage.Pickers.PickerViewMode.List;
6.             picker.SuggestedStartLocation = PickerLocationId.DocumentsLibrary;
7.             picker.FileTypeFilter.Add(".png");
8.  
9.             var file = await picker.PickSingleFileAsync();
10.             if (file != null)
11.             {
12.                 this.onFileSelected?.Invoke(file.Name);
13.             }
14.         }
15. #endif
16.     }

If I build the Project and try to access the FilePicker I got the following error:


I hope someone could help me.

 

OpenFilePicker needs to be called on the UI thread. See this post for details:

Thank you very much it's working now.

 

what is ShowOpenPanel input?

1. public static string ShowOpenPanel(bool includeFiles, bool includeDirectories)
2. {
3. Application.InvokeOnUIThread(async () => {
4. var filePicker = new FileOpenPicker();
5. filePicker.FileTypeFilter.Add("*");
6. var file = await filePicker.PickSingleFileAsync();
7. }, false);
8. return string.Empty;
9. }
