Examples
The following example shows how to obtain a type associated with a custom section. For the implementation of the custom section, refer to the code example in the ConfigurationConverterBase class reference.
using System;
using System.IO;
using System.ComponentModel;
using System.Configuration;
namespace Samples.AspNet
{
public sealed class UsingTypeNameConverter
{
public static void GetTypeName()
{
try
{
CustomSection section =
ConfigurationManager.GetSection("CustomSection")
as CustomSection;
Console.WriteLine("CustomSection type: {0}",
section);
}
catch (System.Exception e)
{
Console.WriteLine(e.Message);
}
}
}
}
Imports System.IO
Imports System.ComponentModel
Imports System.Configuration
NotInheritable Public Class UsingTypeNameConverter
Public Shared Sub GetTypeName()
Try
Dim section As CustomSection = _
ConfigurationManager.GetSection("CustomSection")
Console.WriteLine( _
"CustomSection type: {0}", section)
Catch e As System.Exception
Console.WriteLine(e.Message)
End Try
End Sub
End Class
The following example is a configuration excerpt used by the previous example.
<?xml version="1.0" encoding="utf-8"?>
<configuration>

<section name="CustomSection"
type="Samples.AspNet.CustomSection,

Version=1.0.0.0, Culture=neutral,

</configuration>
Remarks
This type, like all the other configuration converter types, converts strings found in the configuration file to and from the related strongly typed properties.
In particular, the TypeNameConverter class converts a String value, assigned to a configuration type, to a Type value and vice versa. The type referred to is the class responsible for processing the configuration it is associated with.
