Converter Converter Converter Converter Class

Definition

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.
