Storing an object to a file in Windows 8 apps

Quote:

So, what are the ways of saving the objects to files in Windows 8 apps(C#).

Have a look at this Tip:
Windows 8 App - Data storage in files using Windows.Storage namespace[^]

I am getting an Exception:
An exception of type 'System.Runtime.Serialization.InvalidDataContractException' occurred in System.Runtime.Serialization.dll but was not handled in user code

Additional information: Type 'Windows.UI.Xaml.Media.ImageSource' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute. If the type is a collection, consider marking it with the CollectionDataContractAttribute. See the Microsoft .NET Framework documentation for other supported types.

at serializer.WriteObject(stream1, record1)

The class is:

[DataContract(Namespace = "http://www.abcdefg.com")]
    internal class Record
    {
        private double n1;
        private BitmapImage bimg;

        internal Record(double n1, BitmapImage bimg)
        {
            this.n1 = n1;
            this.bimg = bimg;
        }
        [DataMember]
        internal BitmapImage image
        {
            get { return bimg; }
            set { bimg = value; }
        }

        [DataMember]
        internal double OperandNumberOne
        {
            get { return n1; }
            set { n1 = value; }
        }

        public override string ToString()
        {
            return string.Format("Record: {0} and an image: {1}", n1, bimg.ToString());
        }
    }

and the Serialization is done here:

private async void save_Click(object sender, RoutedEventArgs e)
        {
            FileOpenPicker openPicker = new FileOpenPicker();
            openPicker.ViewMode = PickerViewMode.List;
            openPicker.SuggestedStartLocation = PickerLocationId.ComputerFolder;
            openPicker.FileTypeFilter.Add(".jpg");
            StorageFile file = await openPicker.PickSingleFileAsync();
            IRandomAccessStream imageStream = await file.OpenReadAsync();
            bitmapImage = new BitmapImage();
            bitmapImage.SetSource(imageStream);
            ImgUIelement.Source= bitmapImage;

            
            MemoryStream stream1 = new MemoryStream();
            //Serialize the Record object to a memory stream using DataContractSerializer.
            DataContractSerializer serializer = new DataContractSerializer(typeof(Record));
            Record record1 = new Record(1, bitmapImage);
            serializer.WriteObject(stream1, record1);   // EXCEPTION HERE

            tbx_OP.Text = "Written to Stream:" + record1.ToString();

            FileSavePicker fileSavePicker = new FileSavePicker();
            fileSavePicker.DefaultFileExtension = ".bla";
            fileSavePicker.FileTypeChoices.Add("Bla Files", new List<string> { ".bla" });
            fileSavePicker.SuggestedFileName = "New Bla File";
            fileSavePicker.SuggestedStartLocation = PickerLocationId.DocumentsLibrary;
            var sfile = await fileSavePicker.PickSaveFileAsync();

            using (Stream x = await sfile.OpenStreamForWriteAsync())
            {
                x.Seek(0, SeekOrigin.Begin);
                stream1.WriteTo(x);
            }
}
</string>

My requirement is to serialize an object consisting a List of Images and List of StorageFiles into a File, in my Windows Store App. I am trying to find intially whether it is possible to serialize a Single Image.
If possible could anyone please provide the sample code for a class like this..

public class ExClass
{
    List<Image> imgList = new List<Image>();
    List<StorageFile> audList = new List<StorageFile>();
}

I did'nt find any examples for serializing Types other than the Strings,Int,Double..Primitive ones.
