Represents a configuration element in a configuration file.
public ref class Converter : System::Configuration::ConfigurationElement
public class Converter : System.Configuration.ConfigurationElement
type Converter = class
inherit ConfigurationElement
Public Class Converter
Inherits ConfigurationElement
- Inheritance
Examples
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];
}
' Get the Web application configuration.
Dim configuration As System.Configuration.Configuration = _
WebConfigurationManager.OpenWebConfiguration("/aspnetTest")
' Get the external JSON section.
Dim jsonSection As ScriptingJsonSerializationSection = _
CType(configuration.GetSection( _
"system.web.extensions/scripting/webServices/jsonSerialization"), _
ScriptingJsonSerializationSection)
'Get the converters collection.
Dim converters As ConvertersCollection = _
jsonSection.Converters
If Not (converters Is Nothing) AndAlso _
converters.Count > 0 Then
' Get the first registered converter.
Dim converterElement As Converter = converters(0)
End If
Remarks
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.
