    copied!<p>This is generic code for configuration collection :</p> <pre><code>public class GenericConfigurationElementCollection&lt;T&gt; : ConfigurationElementCollection, IEnumerable&lt;T&gt; where T : ConfigurationElement, new() { List&lt;T&gt; _elements = new List&lt;T&gt;(); protected override ConfigurationElement CreateNewElement() { T newElement = new T(); _elements.Add(newElement); return newElement; } protected override object GetElementKey(ConfigurationElement element) { return _elements.Find(e =&gt; e.Equals(element)); } public new IEnumerator&lt;T&gt; GetEnumerator() { return _elements.GetEnumerator(); } } </code></pre> <p>After you have <code>GenericConfigurationElementCollection</code>, you can simple use it in the config section (this is an example from my Dispatcher):</p> <pre><code>public class DispatcherConfigurationSection: ConfigurationSection { [ConfigurationProperty("maxRetry", IsRequired = false, DefaultValue = 5)] public int MaxRetry { get { return (int)this["maxRetry"]; } set { this["maxRetry"] = value; } } [ConfigurationProperty("eventsDispatches", IsRequired = true)] [ConfigurationCollection(typeof(EventsDispatchConfigurationElement), AddItemName = "add", ClearItemsName = "clear", RemoveItemName = "remove")] public GenericConfigurationElementCollection&lt;EventsDispatchConfigurationElement&gt; EventsDispatches { get { return (GenericConfigurationElementCollection&lt;EventsDispatchConfigurationElement&gt;)this["eventsDispatches"]; } } } </code></pre> <p>The Config Element is config Here:</p> <pre><code>public class EventsDispatchConfigurationElement : ConfigurationElement { [ConfigurationProperty("name", IsRequired = true)] public string Name { get { return (string) this["name"]; } set { this["name"] = value; } } } </code></pre> <p>The config file would look like this:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8" ?&gt; &lt;dispatcherConfigurationSection&gt; &lt;eventsDispatches&gt; &lt;add name="Log" &gt;&lt;/add&gt; &lt;add name="Notification" &gt;&lt;/add&gt; &lt;add name="tester" &gt;&lt;/add&gt; &lt;/eventsDispatches&gt; &lt;/dispatcherConfigurationSection&gt; </code></pre> <p><em>Hope it help !</em></p>
