XML Serialization for Complex Data Types

XML serialization for complex data types including GDI objects, Hashtable, and List.


Looking up on Google about XML serialization would give us many links about problems, questions, and other things about it. But nowhere, did I find an article that has it all. So if you are looking at how to serialize hashtables, GDI objects (GraphicsPath, Fonts...), etc., read on.


All the code has been verified under Microsoft FxCop 1.35. If you're not very familiar with XML or serialization, refer to MSDN.

Using the code

An XML file can store any of the following: basic type objects (like DateTime...), GDI objects (GraphicsPath, Font, Pen...), or complex objects (Hashtable ...).

The main serialization operation is is done inside Configuration.cs. All new XML object types are listed in XmlUtility.GetXmlTypes. The Save and Load functions are not very difficult to understand.

You can have a Hashtable of anything (integer, list). Just take a look at the code in the InitDefault function in BasicConfiguration, GdiConfiguration, and OtherConfiguration.

// Main code
    string           strConfigurationFile = @"./config.XML";
    Configuration    Config = new Configuration ();
    Configuration    Config2;

    // Save configuration file
    Console.WriteLine ("Writing configuration file");
    Config.Save (strConfigurationFile);

    // Assign new values
    Console.WriteLine ("Reset values");
    Config.BasicConfiguration.MyFloat    = 0.0f;
    Config.BasicConfiguration.MyString   =String.Empty;
    Config.BasicConfiguration.MyInt      = 64;

    // Node test
    Console.WriteLine ("Node test");
    XmlNodeContainer ScreenNode = (XmlNodeContainer)
    XmlKeyAndValue    KeyAndValue1 = (XmlKeyAndValue)ScreenNode["ResolutionX"];
    XmlKeyAndValue    KeyAndValue2 = (XmlKeyAndValue)ScreenNode["ResolutionY"];
    Console.WriteLine (string.Format ("Resolution saved : {0}x{1}", 
                       KeyAndValue1.Value, KeyAndValue2.Value));

    XmlKeyAndValue    KeyAndValue3 = (XmlKeyAndValue)((XmlNodeContainer)
         Config.OtherConfiguration.XmlNodeContainer["Network"])["MAC ADDRESS"];
    Console.WriteLine (string.Format ("Network MAC ADDRESS saved : {0}", 

    // Reload default values
    Console.WriteLine ("Reload default configuration");
    Config2 = Configuration.Load (strConfigurationFile);
    Console.WriteLine ("Ok");
catch (Exception e)
    Console.WriteLine ("ERROR");
    Console.WriteLine (e.ToString ());

Console.WriteLine ("Press Return to quit");
Console.ReadLine ();

I hope you'll find it useful.

Points of interest

I've tried to make the code as simple as possible so that anyone can upgrade it.

Bug report

There is one 'bug' where I need some help. In xmltranslatorelement.cs (line 111), FxCop returns this error: CollectionPropertiesShouldBeReadOnly. So you'd prolly think that you could remove the set() attribute, but here comes the trouble. We must implement the Add and GetEnumerator functions from IEnumerable but we have a hashtable. If someone knows how to break this error...
