TypeNameConverter Class

Converts between type and string values. This class cannot be inherited.

Namespace:  System.Configuration
Assembly:  System.Configuration (in System.Configuration.dll)

public sealed class TypeNameConverter : ConfigurationConverterBase

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.

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()

                CustomSection section =
                    as CustomSection;

                Console.WriteLine("CustomSection type: {0}",
            catch (System.Exception e)


The following example is a configuration excerpt used by the previous example.

<?xml version="1.0" encoding="utf-8"?>

    <section name="CustomSection" 
      Version=, Culture=neutral, 
      restartOnExternalChanges="true" />
  <CustomSection fileName="default.txt" maxIdleTime="90" 
    timeDelay="infinite" cdStr="str0, str1" permission="Read"
