First we need to create a custom ConfigurationElement. This configuration element only has a value attribute.
public class MyConfigurationElement : ConfigurationElement
{
/// <summary>
/// Initializes a new instance of the <see cref="ValueConfigurationElement"/> class.
/// </summary>
public MyConfigurationElement ()
{}
/// <summary>
/// Gets or sets the value.
/// </summary>
/// <value>The value.</value>
[ConfigurationProperty("value", IsRequired = true)]
public string Value
{
get { return this["value"] as string; }
set { this["value"] = value as string; }
}
}
Second we need to create the custom ConfigurationSection :
public class MyCustomSection : ConfigurationSection
{
/// <summary>
/// Gets or sets the property 1.
/// </summary>
/// <value>The property 1.</value>
[ConfigurationProperty("Property1", IsRequired = true)]
public MyConfigurationElement Property1
{
get { return (MyConfigurationElement)this["Property1"]; }
set { this["Property1"] = value; }
}
/// <summary>
/// Gets or sets the Property 2.
/// </summary>
/// <value>The Property 2.</value>
[ConfigurationProperty("Property2", IsRequired = true)]
public MyConfigurationElement Property2
{
get { return (MyConfigurationElement)this["Property2"]; }
set { this["Property2"] = value; }
}
}
This custom section has 2 MyConfigurationElements: Property1 and Property2
And finally, the application config
<sectionGroup name="CustomGroup" type="System.Configuration.ConfigurationSectionGroup, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" >
<section name="CustomSection" type=" MyCustomSection, Version=1.0.0.0, Culture=neutral " />
</sectionGroup>
<CustomGroup>
<CustomSection>
<Property1 value="0123456789" />
<Property2 value="Lorem ipsum dolor sit amet" />
</CustomSection>
</CustomGroup>
See here how you can add this section programmatically to your web.config
