Question

My custom config section looks like this:

  <MySection>
    <add name="a" value="111"/>
    <add name="b" value="222"/>
    <add name="c" value="333"/>
    ...
  </MySection>

I know how to write a custom config section, but how to iterate through all its entries?

If you want to parse your section use:

var config = (SampleConfigurationSection)ConfigurationManager.GetSection("sampleConfiguration");

config.YourCustomProperty = "Hello World";

If you want to iterate through the XML elements manually (which would be a really strange requirement), you could use LINQ to XML

using System.Xml.Linq;

....

var xml = XDocument.Load("path to your config file");

var section = from e in xml.Root.Elements("your section name").Elements()
              select e;

If you need dynamic items, then perhaps you could use the ConfigurationElementCollection and then parse your section and work with your collection objects instead of working with the XML directly
