Cinchoo – Configuration framework, part 4

Using ChoFileNameValueConfigStorage

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

In this part, I’ll go over the details of using ChoFileNameValueConfigStorage in your application. It provides name/value-pair configuration information from file source. This is the default configuration storage used by ChoNameValueConfigurationSectionHandlerChoNameValueConfigurationSectionAttribute is the corresponding attribute used to decorate the configuration object class.

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

[ChoNameValueConfigurationSection("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. Now 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>
  <configSections>
    <section name="sample" type="Cinchoo.Core.Configuration.ChoNameValueSectionHandler, Cinchoo.Core" />
  </configSections>
  <sample>
    <add key="name" value="Mark" />
    <add key="message" value="Hello World!" />
  </sample>
</configuration>
