The Converter type exposes the following members.

  NameDescription
Public methodConverterInitializes a new instance of the Converter class.

  NameDescription
Public propertyCurrentConfigurationGets a reference to the top-level Configuration instance that represents the configuration hierarchy that the current ConfigurationElement instance belongs to. (Inherited from ConfigurationElement.)
Public propertyElementInformationGets an ElementInformation object that contains the non-customizable information and functionality of the ConfigurationElement object. (Inherited from ConfigurationElement.)
Protected propertyElementPropertyGets the ConfigurationElementProperty object that represents the ConfigurationElement object itself. (Inherited from ConfigurationElement.)
Protected propertyEvaluationContextGets the ContextInformation object for the ConfigurationElement object. (Inherited from ConfigurationElement.)
Protected propertyHasContextGets a value that indicates whether the CurrentConfiguration property is null. (Inherited from ConfigurationElement.)
Protected propertyItem[ConfigurationProperty]Gets or sets a property or attribute of this configuration element. (Inherited from ConfigurationElement.)
Protected propertyItem[String]Gets or sets a property, attribute, or child element of this configuration element. (Inherited from ConfigurationElement.)
Public propertyLockAllAttributesExceptGets the collection of locked attributes. (Inherited from ConfigurationElement.)
Public propertyLockAllElementsExceptGets the collection of locked elements. (Inherited from ConfigurationElement.)
Public propertyLockAttributesGets the collection of locked attributes (Inherited from ConfigurationElement.)
Public propertyLockElementsGets the collection of locked elements. (Inherited from ConfigurationElement.)
Public propertyLockItemGets or sets a value indicating whether the element is locked. (Inherited from ConfigurationElement.)
Public propertyNameGets or sets the unique identifier for the converter.
Protected propertyPropertiesGets a collection of configuration-element properties. (Overrides ConfigurationElement.Properties.)
Public propertyTypeGets or sets the fully qualified type name of the JavaScriptConverter object.

Public methodIsReadOnlyGets a value indicating whether the ConfigurationElement object is read-only. (Inherited from ConfigurationElement.)
Protected methodListErrorsAdds the invalid-property errors in this ConfigurationElement object, and in all subelements, to the passed list. (Inherited from ConfigurationElement.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Protected methodOnDeserializeUnrecognizedAttributeGets a value indicating whether an unknown attribute is encountered during deserialization. (Inherited from ConfigurationElement.)
Protected methodOnDeserializeUnrecognizedElementGets a value indicating whether an unknown element is encountered during deserialization. (Inherited from ConfigurationElement.)
Protected methodOnRequiredPropertyNotFoundThrows an exception when a required property is not found. (Inherited from ConfigurationElement.)
Protected methodPostDeserializeCalled after deserialization. (Inherited from ConfigurationElement.)
Protected methodPreSerializeCalled before serialization. (Inherited from ConfigurationElement.)
Protected methodResetResets the internal state of the ConfigurationElement object, including the locks and the properties collections. (Inherited from ConfigurationElement.)
Protected methodResetModifiedResets the value of the IsModified method to false when implemented in a derived class. (Inherited from ConfigurationElement.)
Protected methodSerializeElementWrites the contents of this configuration element to the configuration file when implemented in a derived class. (Inherited from ConfigurationElement.)
Protected methodSerializeToXmlElementWrites the outer tags of this configuration element to the configuration file when implemented in a derived class. (Inherited from ConfigurationElement.)
Protected methodSetPropertyValueSets a property to the specified value. (Inherited from ConfigurationElement.)
Protected methodSetReadOnlySets the IsReadOnly property for the ConfigurationElement object and all subelements. (Inherited from ConfigurationElement.)

The Converter class enables you to programmatically access and modify the configuration settings related to converters that are used by AJAX-enabled ASP.NET applications.

To create custom conversion functionality, you can create a class that inherits from the JavaScriptConverter class. After the converter has been created, you can register it for use in the configuration file of your Web application.

The following configuration file excerpt shows how to declaratively specify values for properties of the Converter class.

<system.web.extensions>
  <scripting>
    <webServices>
      <jsonSerialization>
        <converters>
          <add name="ConvertMe" type="Acme.SubAcme.ConvertMeTypeConverter" />
        </converters>
      </jsonSerialization>
    </webServices>
  </scripting>
</system.web.extensions>

The following example demonstrates how to access Converter programmatically.

// Get the Web application configuration.
System.Configuration.Configuration configuration =
    WebConfigurationManager.OpenWebConfiguration("/aspnetTest");

// Get the external JSON section.
ScriptingJsonSerializationSection jsonSection =
    (ScriptingJsonSerializationSection)configuration.GetSection(
    "system.web.extensions/scripting/webServices/jsonSerialization");

//Get the converters collection.
ConvertersCollection converters =
    jsonSection.Converters;

if ((converters != null) && converters.Count > 0)
{
    // Get the first registered converter.
    Converter converterElement = converters[0];
}
