copied!<p>If all you had was basic types all you would need to do is put a <a href="http://msdn.microsoft.com/en-us/library/system.serializableattribute%28v=vs.110%29.aspx" rel="nofollow"><code>[Serializable]</code></a> attribute on your class and you could use a <a href="http://msdn.microsoft.com/en-us/library/system.xml.serialization.xmlserializer%28v=vs.110%29.aspx" rel="nofollow"><code>XmlSeralizer</code></a> to write it out to a file.</p> <pre><code>[Serializable] public class cEspecie { //...Snip... } </code></pre> <p>However for that to work all of the elements inside the class must also be marked <code>[Serializable]</code>, unfortunately <code>BitmapImage</code> is not.</p> <p>To work around this we mark the unseralizeable object to be skipped, we then provide a new property that can be seralized that can represent the image</p> <pre><code>[Serializable] public class cEspecie { //...Snip... [XmlIgnore] //Skip this object public BitmapImage Imagen { get { return imagen; } set { imagen = value; } } [Browsable(false), EditorBrowsable(EditorBrowsableState.Never)] //This creates a secret hidden property that does not show up in intellisense [XmlElement("Imagen")] //It uses the name of the real property for it's name public BitmapImageSearalizer ImagenSerialized { get { return new BitmapImageSearalizer(imagen); } set { imagen = value.GetSearalizedImage(); } } } [Serializable] internal BitmapImageSearalizer { public BitmapImageSearalizer(BitmapImage sourceImage) { //...Snip... } public BitmapImage GetSearalizedImage() { //...Snip... } //...Snip... } </code></pre> <p>I leave it to you to write <code>BitmapImageSearalizer</code> I have not worked with the class enough to write it. </p> <p>To show you a more complete known working example of how to do it, here is a snippet from one of my projects where I did this exact trick with just a plain <a href="http://msdn.microsoft.com/en-us/library/system.drawing.bitmap%28v=vs.110%29.aspx" rel="nofollow"><code>Bitmap</code></a> object</p> <pre><code> /// <summary> /// 1 bit per pixel bitmap to use as the image source. /// </summary> [XmlIgnore] public Bitmap BitmapImage { get { return _Bitmap; } set { if (value.PixelFormat != System.Drawing.Imaging.PixelFormat.Format1bppIndexed) throw new FormatException("Bitmap Must be in PixelFormat.Format1bppIndexed"); _Bitmap = value; } } [Browsable(false), EditorBrowsable(EditorBrowsableState.Never)] [XmlElement("Bitmap")] public byte[] BitmapSerialized { get { // serialize if (BitmapImage == null) return null; using (MemoryStream ms = new MemoryStream()) { BitmapImage.Save(ms, ImageFormat.Bmp); return ms.ToArray(); } } set { // deserialize if (value == null) { BitmapImage = null; } else { using (MemoryStream ms = new MemoryStream(value)) { BitmapImage = new Bitmap(ms); } } } } </code></pre>
