使用.NET创建可自定义的配置

OnDeserializeUnrecognizedElement

override protected bool OnDeserializeUnrecognizedElement (string elementName, System.Xml.XmlReader 
{
    if (sNames.ContainsKey (elementName))
    {
        var elementType = sNames[elementName];
        if (elementType != null)
        {
            var element = Activator.CreateInstance (elementType) as LoggerConfigurationElement;
            if (element != null)
            {
                element.DeserializeElementForConfig (reader, false);
                BaseAdd (element);
            }
        }

        return true;
    }

    return base.OnDeserializeUnrecognizedElement (elementName, reader);
}
