元の質問とコード：ConfigurationSectionでカスタマイズされたIEnumerable

これに対する解決策を進め、@ Daniel Hilgarthの回答で、これを変更しました（app.config）：

<section name="Disk"
         type="ConsoleApplication1_ConfigurationEnumerable.PathsConfigSection"/>

これに：

    <section name="Disk"
             type="ConsoleApplication1_ConfigurationEnumerable.PathsConfigSection,
             ConsoleApplication1_ConfigurationEnumerable"/>

今、私はこれとは別の例外があります：

PathsConfigSection.Pathsプロパティに次の属性を追加してみてください。

    [ConfigurationCollection(typeof(Paths), AddItemName = "Path")]

これで、次のようになります。

    [ConfigurationProperty("Paths")]
    [ConfigurationCollection(typeof(Paths), AddItemName = "Path")]
    public Paths Paths
    {
        get
        {
            var o = this["Paths"];
            return o as Paths;
        }
    }

構成は次のようになります。

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="Disk" type="ConsoleApplication1.DiskConfigSection, ConsoleApplication1"/>
  </configSections>
  <Disk>
    <Paths>
      <Path name="one" permission="1" />
      <Path name="two" permission="2" />
      <Path name="three" permission="3" />
    </Paths>
  </Disk>
</configuration>

これで、クラスは次のようになります。

using System.Configuration;

namespace ConsoleApplication1
{
class Program
{
    static void Main(string[] args)
    {
        var t = DiskConfigSection.GetConfig();
        // Put a breakpoint on the line after this and put a watch on t
    }
}

public class Path : ConfigurationElement
{
    [ConfigurationProperty("name", IsRequired = true)]
    public string Name
    {
        get
        {
            return (string)this["name"];
        }
    }

    [ConfigurationProperty("permission", IsRequired = true)]
    public string Permission
    {
        get
        {
            return (string)this["permission"];
        }
    }
}

public class Paths : ConfigurationElementCollection
{
    public Path this[int index]
    {
        get
        {
            return BaseGet(index) as Path;
        }
        set
        {
            if (BaseGet(index) != null)
            {
                BaseRemoveAt(index);
            }
            BaseAdd(index, value);
        }
    }

    protected override ConfigurationElement CreateNewElement()
    {
        return new Path();
    }
    protected override object GetElementKey(ConfigurationElement element)
    {
        return ((Path)element).Name;
    }
}

public class DiskConfigSection : ConfigurationSection
{
    public static DiskConfigSection GetConfig()
    {
        var b = ConfigurationManager.GetSection("Disk") != null;
        return b ? (DiskConfigSection)ConfigurationManager.GetSection("Disk") : new DiskConfigSection();
    }

    [ConfigurationProperty("Paths")]
    [ConfigurationCollection(typeof(Paths), AddItemName = "Path")]
    public Paths Paths
    {
        get
        {
            var o = this["Paths"];
            return o as Paths;
        }
    }
}
}

コンソールアプリでテストしましたが、構成が完全に読み込まれます。
