Récupère le chemin d'image actuel

Question

Comment obtenir le chemin actuel d'une image dans wpf? J'essaye de construire une fonction générique qui change l'image à l'autre image en ajoutant juste un "focus" à la fin du nom de l'image, btu ne peut pas sembler obtenir le chemin courant ainsi je peux faire le changement

une idée?

EDIT:

private void image1_MouseEnter(object sender, MouseEventArgs e) 
{ 
     string buf = ((BitmapImage)(sender as Image).Source).UriSource.ToString(); 
     string pack = buf.Substring(0, buf.LastIndexOf('.')) + "focus" + buf.Substring(buf.LastIndexOf('.')); 

     SetImageFullURI(sender as Image, pack); 
}

Answer 1

Vous pouvez utiliser BitmapImage objets et pointez votre image.Source les si nécessaire

Bitm apImage a bitmapImage.UriSource propriété

Answer 2

Vous pouvez modifier la source sous-jacente pour votre Image dans votre code derrière comme ça ... où i est votre défini Image provenant XAML ou définies ailleurs. Dans cet exemple, path n'est pas utilisé; Cependant, vous l'utiliserez lorsque vous ajouterez focus comme mention dans votre question.

Image i = new Image(); 

BitmapImage bi = i.Source as BitmapImage; 
bi.BeginInit(); 

Uri uri = bi.UriSource; 
String path = uri.AbsolutePath; 
String newPath = @"C:\Images\blah.png"; 
Uri newUri = new Uri(newPath); 

bi.UriSource = newUri; 
bi.EndInit(); 

EDIT:

Sur la base de votre code essayer ...

string buf = ((BitmapFrame)(sender as Image).Source).BaseUri.ToString();
