Write ICON data to an xml file

[SteveT]

I have a structure that contains both 32x32 and 16x16 icons plus some text.
I want to write all this to an XML file so that I can recover the icons later
in an application. Can someone tell me how to properly serialize the
System.Drawing.Icon structure to an XML file?

The following code doesn't write the icon information to the xml file.

private void CreateXmlFile(string filename)
{

string fullPath = String.Format(@"{0}", filename);

XmlWriter xw = null;
try
{
XmlSerializer xSer = new XmlSerializer(typeof(AppIconList));
XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = true;
settings.ConformanceLevel = ConformanceLevel.Auto;
xw = XmlWriter.Create(fullPath, settings);
xSer.Serialize(xw, this.List);
}
catch (Exception e)
{
System.Windows.MessageBox.Show(e.Message);
}
finally
{
// Ensure the file is closed.
if (xw != null)
xw.Close();
}
}

Hi Steve,

From your description, you have an .NET appliccation which will use some
Icon file, and you also want to persist them into a XML file so that you
can retrieve them out and reuse next time, correct?

In my opinion, since Icons are actually of binary image stream, you'd
better still persist them through their binary content, however, since the
persistent storage is xml file, you can use Convertion to convert the
binary stream of the Icon from binary to string. For example,you can use
Convert.ToBase64String

#Convert..::.ToBase64String Method
http://msdn2.microsoft.com/en-us/library/system.convert.tobase64string.aspx

To get the binary stream of a Icon object, you can simply call its "Save"
method and provide a "MemoryStream" class, then, you can get the saved
byte[] array of your Icon object and save it into XML file.

#Icon..::.Save Method
http://msdn2.microsoft.com/en-us/library/system.drawing.icon.save.aspx

Next time, you just need to extract the binary blob(convert from base64
string to binary) and use Icon's c onstructor to recreate the Icon. How do
you think?

Sincerely,
