Cinchoo – Configuration framework, part 9

Using ChoRegistryConfigStorage

Download sample source files (Require .NET 4.0 / Visual Studio 2010)

In this section, I’ll go over the details of using ChoRegistryConfigStorage in your application. It’s a custom configuration section handler enables application to read and write application settings from Windows System Registry.

1. Define the configuration section object decorated with ChoRegistryConfigurationSectionAttribute as below.

[ChoRegistryConfigurationSection("sample", "HKLM/Software/Sample")]
public class SampleConfigSection : ChoConfigurableObject
{
	#region Instance Data Members (Public)

	[ChoPropertyInfo("name", DefaultValue="Mark")]
	public string Name;

	[ChoPropertyInfo("message", DefaultValue="Hello World!")]
	public string Message;

	#endregion

	[ChoAfterConfigurationObjectLoadedHandler]
	void OnAfterConfigurationObjectLoaded(object sender, ChoConfigurationObjectEventArgs e)
	{
		Console.WriteLine(sender.ToString());
	}
}

2. Instantiate and use it as below.

class Program
{
	static void Main(string[] args)
	{
		SampleConfigSection sampleConfigSection = new SampleConfigSection();
		Console.WriteLine(sampleConfigSection.ToString());
	}
}

The configuration section will be generated automatically for the first time in HelloWorld.exe.xml as below.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <sample cinchoo:registryKey="HKLM\Software\sample" xmlns:cinchoo="http://schemas.cinchoo.com/cinchoo/01/framework" />
  <configSections>
    <section name="sample" type="Cinchoo.Core.Configuration.ChoDictionarySectionHandler, Cinchoo.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=b7dacd80ff3e33de" />
  </configSections>
</configuration>

Also the corresponding registry entries are created automatically if not exists as below
