次の例では、プログラムで ScriptingJsonSerializationSection にアクセスする方法を示します。

// 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
