app.configに基づいて、以下の3〜5行目の例に示すように列の要素を取得できるようにしたいと思います。これを実現するには、どのようにコードを書く必要がありますか。app.configを変更する必要がある場合は、変更します。

1. var bounceProviders = ConfigurationManager.GetSection("BounceProviders") as BounceProvidersSection;
2. var providerColumns = bounceProviders.Providers[0].Columns;
3. var emailColumn = providerColumns.Email;
4. var dateColumn = providerColumns.Date;
5. var messageColumn = providerColumns.Message;

app.config

<BounceProviders>
  <Providers>
    <Provider Name="p1">        
      <Columns>
          <Email Name="My Email" />
          <Date Name="My Date" />
          <Message Name="My Message" />               
      </Columns>
    </Provider>  
    <Provider Name="p2">
      <Columns />
    </Provider>    
  </Providers>
</BounceProviders>

ConfigurationSection

public class BounceProvidersSection : ConfigurationSection
{
    [ConfigurationCollection(typeof(ConfigCollection<BounceProviderConfig>), AddItemName = "Provider")]
    [ConfigurationProperty("Providers", IsRequired = true)]
    public ConfigCollection<BounceProviderConfig> Providers
    {
        get { return (ConfigCollection<BounceProviderConfig>)this["Providers"]; }
        set { this["Providers"] = value; }
    }                
}

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

ConfigCollection

public class ConfigCollection<T> : ConfigurationElementCollection
        where T : ConfigurationElement, new()
{        
    protected override ConfigurationElement CreateNewElement()
    {
        return new T();
    }

    protected override object GetElementKey( ConfigurationElement element )
    {
        return element.GetHashCode();
    }

    public T this[int index]
    {
        get
        {
            return ( T )BaseGet( index );
        }
        set
        {
            if ( BaseGet( index ) != null )
            {
                BaseRemoveAt( index );
            }
            BaseAdd( index, value );
        }
    }

    new public T this[string Name]
    {
        get
        {
            return ( T )BaseGet( Name );
        }
    }
}

私はそれを考え出した

public class BounceProvidersSection : ConfigurationSection
{
    [ConfigurationCollection(typeof(ConfigCollection<BounceProviderConfig>), AddItemName = "Provider")]
    [ConfigurationProperty("Providers", IsRequired = true)]
    public ConfigCollection<BounceProviderConfig> Providers
    {
        get { return (ConfigCollection<BounceProviderConfig>)this["Providers"]; }
        set { this["Providers"] = value; }
    }                
}

public class BounceProviderConfig : ConfigurationElement
{
    [ConfigurationProperty("Id", IsRequired = true)]
    public int Id
    {
        get { return (int)this["Id"]; }
        set { this["Id"] = value; }
    }

    [ConfigurationProperty("Columns", IsRequired = false)]
    public BounceProviderColumns Columns
    {
        get { return (BounceProviderColumns)this["Columns"]; }
        set { this["Columns"] = value; }
    }

    public static BounceProviderConfig GetByProviderId(int providerId)
    {
        var section = ConfigUtils.GetConfigurationSection<BounceProvidersSection>("BounceProviders");
        foreach (BounceProviderConfig provider in section.Providers)
        {
            if (provider.Id == providerId)
                return provider;
        }

        return null;
    }
}

public class BounceProviderColumns : ConfigurationElement
{
    [ConfigurationProperty("Email", IsRequired = true)]
    public ColumnConfig Email
    {
        get { return (ColumnConfig)this["Email"]; }
        set { this["Email"] = value; }
    }

    [ConfigurationProperty("Date", IsRequired = true)]
    public DateColumnConfig Date
    {
        get { return (DateColumnConfig)this["Date"]; }
        set { this["Date"] = value; }
    }

    [ConfigurationProperty("Message", IsRequired = true)]
    public ColumnConfig Message
    {
        get { return (ColumnConfig)this["Message"]; }
        set { this["Message"] = value; }
    }        
}

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