Using ChoStandardAppSettingsConfigStorage

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

In this section, I’ll go over the details of using ChoStandardAppSettingsConfigStorage in your application. It’s a custom configuration section handler provides the ability to read and write  custom application key/value-pair configuration information under <appSettings> section in App.config file.

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

[ChoStandardAppSettingsConfigurationSection]
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.config (please note that this section is NOT created in HelloWorld.exe.xml file) as below

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="name" value="Mark" />
    <add key="message" value="Hello World!" />
  </appSettings>
</configuration>
