How to parse app.config using ConfigurationManager?

I used a specific method to parse my app.config file. Then I was told that using the ConfigurationManager is better and easier. But the point is, I don't know how to do it using the ConfigurationManager.

My original code looked like this:

   XmlNode xmlProvidersNode;
    XmlNodeList xmlProvidersList;
    XmlNodeList xmlTaskFactoriesList;

    XmlDocument xmlDoc = new XmlDocument();
    xmlDoc.Load("app.config");
    xmlProvidersNode = xmlDoc.DocumentElement.SelectSingleNode("TaskProviders");
    xmlProvidersList = xmlProvidersNode.SelectNodes("TaskProvider");

    foreach (XmlNode xmlProviderElement in xmlProvidersList)
    {
        if (xmlProviderElement.Attributes.GetNamedItem("Name").Value.Equals(_taskProvider))
        {
            xmlTaskFactoriesList = xmlProviderElement.SelectNodes("TaskTypeFactory");
            foreach (XmlNode xmlTaskFactoryElement in xmlTaskFactoriesList)
            {
                if (xmlTaskFactoryElement.Attributes.GetNamedItem("TaskType").Value.Equals(_taskType))
                {
                    taskTypeFactory = xmlTaskFactoryElement.Attributes.GetNamedItem("Class").Value;
                }
            }
        }
    }

What would be the equivalent using the ConfigurationManager? (Because all I can see is how to get keys, not nodes.)

thanks

Create a class that inherits ConfigurationSection

, called, say MyConfigSection

. Then you can use the method ConfigurationManager.GetSection

to get an instance of your class MyConfigSection

. ConfigurationManager

will do all the parsing, so you have a strongly typed object to work with. Here's a great example to follow.

If you are worried that custom sections create their own class using the Config section class. Here's a usage example.
