Question

I have a class defining a Person. In the class I have it defined like this:

    [XmlIgnore]
    public BitmapImage PhotoSource
        {
        get { return _PhotoSource; }
        set
            {
            _PhotoSource = value;
            NotifyPropertyChanged( "PhotoSource" );
            }
        }

I added the :

      [XmlIgnore]

vs. using the

      [DataMember]

since the serialization will not work with BitmapImage.

However, I still need to save the BitmapImage Local and/or Roaming.

How can that be accomplished?

Thanks,

Create a file from your BitmapImage and then use the StorageFile class to write it to the filesystem.

    Windows.Storage.StorageFile file = await Windows.Storage.StorageFile.GetFileFromApplicationUriAsync(bmImage.UriSource);
    await file.CopyAsync(Windows.Storage.ApplicationData.Current.LocalFolder);

To load the file back into a BitmapImage:

BitmapImage bmImage;
bmImage = new BitmapImage();

bmImage.UriSource = new Uri(new Uri(
     Windows.Storage.ApplicationData.Current.LocalFolder.Path + "\\" +
     Windows.Storage.ApplicationData.Current.LocalFolder.Name), 
     "favicon.scale-100.ico");
