Is it possible to convert an Image in IFormFile

I'm trying to store a model informations in my Data Base, this informations contain an image, so I created a simple view with some entrys, with a media picker button to pick it and an image witch display the picked one.
This is the button method and the store method:
async void Button_Clicked(System.Object sender, System.EventArgs e)
{
var result = await MediaPicker.PickPhotoAsync(new MediaPickerOptions
{
Title = "Please pick a photo"
});
if (result != null)
{
var stream = await result.OpenReadAsync();
resultImage.Source = ImageSource.FromStream(() => stream);
}
}
public async Task SaveMachine()
{
var machine = new Machine
{
Machine_Name = nom.Text,
Machine_Qr = qr.Text,
Files = resultImage
};
await _rest.AddMachine(machine);
await Shell.Current.GoToAsync("..");
}
But I can't create Files = resultImage because the Files in the model is in IFormFile.

Clicked Item not playing song and giving error `The system cannot find the file specified'

I am trying to play a song from my listview in UWP. However when I click on the song (listview item) to play it I get the follwing error:
System.IO.FileNotFoundException: 'The system cannot find the file specified. (Exception from HRESULT: 0x80070002)'
This is my code:
private async Task InitFolderAsync()
{
StorageFolder musicLib = KnownFolders.MusicLibrary;
var files = await musicLib.GetFilesAsync();
foreach (var file in files)
{
StorageItemThumbnail currentThumb = await file.GetThumbnailAsync(ThumbnailMode.MusicView, 50, ThumbnailOptions.UseCurrentScale);
var albumCover = new BitmapImage();
albumCover.SetSource(currentThumb);
var musicProperties = await file.Properties.GetMusicPropertiesAsync();
var musicname = musicProperties.Title;
var musicdur = musicProperties.Duration;
var artist = musicProperties.Artist;
if (artist == "")
{
artist = "Unknown";
}
var album = musicProperties.Album;
if (album == "")
{
album = "Unknown";
}
MusicList.Add(new MusicLib
{
FileName = musicname,
Artist = artist,
Album = album,
Duration = musicdur,
AlbumCover = albumCover,
MusicPath = file.Path
});
}
}
private async void SongClicked(object sender, ItemClickEventArgs e)
{
var file = await KnownFolders.MusicLibrary.GetFileAsync(e.ClickedItem.ToString());
if (file != null)
{
var stream = await file.OpenReadAsync();
mediaElement.SetSource(stream, file.ContentType);
mediaElement.Play();
}
}
private async void objMediaPlayer_MediaEnded(object sender, RoutedEventArgs e)
{
// If the end of the ListView is reached and the last song was played stop.
if ((AudioFilesLV.SelectedIndex + 1) == AudioFilesLV.Items.Count)
{
mediaElement.Stop();
}
else
{
// This line you should try to change. When the last song was not played
//-> select next one and play them.
AudioFilesLV.SelectedIndex = AudioFilesLV.SelectedIndex + 1;
var file = await KnownFolders.MusicLibrary.GetFileAsync(AudioFilesLV.SelectedItem.ToString());
if (file != null)
{
var stream = await file.OpenReadAsync();
mediaElement.SetSource(stream, file.ContentType);
mediaElement.Play();
}
}
}
So basically after you click on the song to play it should then automatically go to the next song and play it. I haven't got to that stage yet as it does not want to play the song I clicked.
Thanks

Try to cast e.ClickedItem to a MusicLib and then pass its MusicPath to the GetFileAsync method:
private async void SongClicked(object sender, ItemClickEventArgs e)
{
var clickedItem = e.ClickedItem as MusicLib;
if (clickedItem != null)
{
var file = await KnownFolders.MusicLibrary.GetFileAsync(clickedItem.MusicPath);
if (file != null)
{
var stream = await file.OpenReadAsync();
mediaElement.SetSource(stream, file.ContentType);
mediaElement.Play();
}
}
}

I do this by looking at my example from here :
https://github.com/ozaksuty/Xamarin-Ogreniyorum/tree/master/MediaPlugin

For future reference I will take the answer of apineda in the comments and elaborate a bit.
The error here is that you have installed the NuGet package only on your shared PCL project. What you need to do is install it on your PCL project as well as your platform projects.
This is because of the way these plugins and Xamarin.Forms work. What actually happens with plugins like these is it offers you an abstract method to work with. Xamarin.Forms is targeting multi-platform, but at the end of the day, it will just transform into a native app. Because of that, it needs an implementation on the actual platform. For this example, code for showing the camera differs greatly between Android and iOS (and all other platforms for that matter).
So, effectively, you are installing the plugin on your shared library to get the method you call upon, but it is not implemented. By then installing the same plugin (but it takes another binary) to your platform project(s), the method will get it's implementation.
It is kind of hard to determine whether a plugin needs to be installed on all projects, or just the shared. Try to decide for yourself if it uses any platform specific stuff.

White tests - folder browser dialog

I have problem with getting of FolderBrowserDialog in white. I think that it should be assigned as a modal window but it isn't.
FolderBrowserDialog in DialogService.cs:
public FolderBrowserResult ShowFolderbrowserDialog(string storageFolder)
{
var dialog = new FolderBrowserDialog
{
Description = storageFolder
};
var result = new FolderBrowserResult
{
Result = dialog.ShowDialog() != DialogResult.OK,
Path = dialog.SelectedPath
};
return result;
}
Method called after click on browse button:
private void OnBrowseForTargetFolder(object sender, RoutedEventArgs e)
{
var result = dialogService.ShowFolderbrowserDialog(Properties.Resources.StorageFolder);
if (result.Result) return;
Project.PathToStorage = result.Path;
completePath = string.Format("{0}\\{1}", result.Path, Guid.NewGuid());
Directory.CreateDirectory(completePath);
}
Test:
public class LoggerTests
{
private Application application;
private MainWindowPage mainWindowPage;
[TestInitialize]
public void TestInitialize()
{
application = Application.Launch(#"PML.exe");
StartBlankApplication();
}
[TestMethod]
public void StartExistingProject()
{
mainWindowPage.StartExistingProjectButton.Click();
var modalWindows = new List<Window>();
Retry.For(() =>
{
modalWindows = mainWindowPage.applicationWindow.ModalWindows();
}, TimeSpan.FromSeconds(5));
var mod = modalWindows;
}
private MainWindowPage StartBlankApplication()
{
var appWindow = application.GetWindow("PML");
mainWindowPage = new MainWindowPage(appWindow);
return mainWindowPage;
}
private NewProjectConfigurationPage ConfigureBlankProject()
{
Window secondAppWindow = null;
Retry.For(() =>
{
secondAppWindow = application.GetWindow("PML");
}, TimeSpan.FromSeconds(5));
var newProjectConfiguration = new NewProjectConfigurationPage(secondAppWindow);
newProjectConfiguration.VesselName.Text = "Test";
newProjectConfiguration.BrowseButton.Click();
return newProjectConfiguration;
}
}
In StartExistingProject method is problem that variable mod is empty. And no FolderBrowserDialog is opened. But when I run app normally everything runs OK.

Solved - There must be setted owner to modal dialog. So
var wrapper = new WindowWrapper(this);
dialog.ShowDialog(wrapper)
solved my problem.

Wikipedia Image list show from wikipedia xml api

I am trying to write a code in which I got as xml format for the first image api from wikipedia. Now I want to parse it through c#. But I cannot get the image while running code. here is my code.
namespace WikiAPIWinForm
{
public partial class WikiForm : Form
{
private const string url1_Image1 = "https://en.wikipedia.org/w/api.php?action=query&titles=File:Schloss%20Neuschwanstein%202013.jpg&prop=imageinfo&iiprop=comment|url|dimensions&format=xml&iiurlwidth=300"; //show 1st image
private const string url1_Image2 = "https://en.wikipedia.org/w/api.php?action=query&titles=File:Neuschwanstein%20castle.jpg&prop=imageinfo&iiprop=comment|url|dimensions&format=xml&iiurlwidth=300";// show another image
private const string url1_Image3 = "https://en.wikipedia.org/w/api.php?action=query&titles=File:Hohenschwangau_-_Schloss_Neuschwanstein5.jpg&prop=imageinfo&iiprop=comment|url|dimensions&format=xml&iiurlwidth=300";// show another image
public WikiForm()
{
InitializeComponent();
}
XDocument xmlDocument1 = XDocument.Load(url1_Image1);
XDocument xmlDocument2 = XDocument.Load(url1_Image2);
XDocument xmlDocument3 = XDocument.Load(url1_Image3);
var image1 = (from page in xmlDocument1.Descendants("page")
select new AllImage
{
Title1 = page.Attribute("title").Value,
Imagerepository1 = page.Attribute("imagerepository").Value,
Url1 = page.Element("imageinfo").Element("ii").Attribute("thumburl").Value
});
ShowImages1(image1);
var image2 = (from page in xmlDocument2.Descendants("page")
select new AllImage
{
Title2 = page.Attribute("title").Value,
Imagerepository2 = page.Attribute("imagerepository").Value,
Url2 = page.Element("imageinfo").Element("ii").Attribute("thumburl").Value
});
ShowImages2(image2);
var image3 = (from page in xmlDocument3.Descendants("page")
select new AllImage
{
Title3 = page.Attribute("title").Value,
Imagerepository2 = page.Attribute("imagerepository").Value,
Url3 = page.Element("imageinfo").Element("ii").Attribute("thumburl").Value
});
ShowImages3(image3);
}
private void ShowImages1(IEnumerable<AllImage> image1)
{
var image = image1.First();
pictureLabel1.Text = image.Title1;
pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;
pictureBox1.LoadAsync(image.Url1);// asynchronous loading
}
private void ShowImages2(IEnumerable<AllImage> image2)
{
var image = image2.First();
pictureLabel2.Text = image.Title2;
pictureBox2.SizeMode = PictureBoxSizeMode.StretchImage;
pictureBox2.LoadAsync(image.Url2);// asynchronous loading
}
private void ShowImages3(IEnumerable<AllImage> image3)
{
var image = image3.First();
pictureLabel3.Text = image.Title3;
pictureBox3.SizeMode = PictureBoxSizeMode.StretchImage;
pictureBox3.LoadAsync(image.Url3);// asynchronous loading
}
}

You need something like
private void button1_Click(object sender, EventArgs e)
{
button1.Enabled = false; // to prevent a new download until you have finished the old one
XDocument xmlDocument = XDocument.Load(url1_Image);
var images = (from page in xmlDocument.Descendants("page")
select new AllImage
{
Title = page.Attribute("title").Value,
Imagerepository = page.Attribute("imagerepository").Value,
Url = page.Element("imageinfo").Element("ii").Attribute("url").Value
});
ShowImages(images);
};
private void ShowImages(IEnumerable<AllImage> images)
{
var image = images.First();
label1.Text = image.Title;
pictureBox1.LoadAsync(image.Url); // asynchronous loading
}
After downloading the image you need to make the button available.
void pictureBox1_LoadCompleted(object sender, AsyncCompletedEventArgs e)
{
button1.Enabled = true;
}
We strongly recommend to give normal names to the controls. For example, buttonLoad, labelTitle, pictureBoxWikiImage.
In addition, I see in XML information about only one image. So, for what the IEnumerable collection?
