FileOpenPicker 在 Windows 11 桌面上的 C# 中不起作用

Question

I am creating a Windows Form App in VS on Windows11 and get this error when I attempt to run my file picker function: System.NotImplementedException: 'The member IAsyncOperation<IReadOnlyList> FileOpenPicker.PickMultipleFilesAsync() is not implemented in Uno.'

The Code:

        var picker = new FileOpenPicker();
        picker.ViewMode = PickerViewMode.Thumbnail;
        picker.SuggestedStartLocation = PickerLocationId.PicturesLibrary;
        picker.FileTypeFilter.Add(".png");

        var files = await picker.PickMultipleFilesAsync();     
        if(files!=null){//stuff n things}

Answer 1

Windows 11 has its own method for opening files. FilePicker will not work in the new App environtment.
