Namespace:  System.ServiceModel.Dispatcher
Assembly:  System.ServiceModel.Web (in System.ServiceModel.Web.dll)

public class JsonQueryStringConverter : QueryStringConverter

Parameters can be specified in a JSON query string within a URL. This class controls how JSON query string parameters are mapped to and from a service operation's parameters when the WebScriptEnablingBehavior is used to process HTTP requests from browser-based ASP.NET AJAX clients.

This class is used internally by the Windows Communication Foundation (WCF)WebScriptEnablingBehavior class for endpoints configured to accept HTTP GET/POST requests with parameters encoded in the URI query string. This class is used to convert between CLR objects and the individual operation request parameter values in the URI query string. Unlike its base type, this class supports values of both primitive and complex types.

JsonQueryStringConverter derives from QueryStringConverter and supports the following types:

Unlike its base type, this converter can handle any type adhering to the Data Contract model. The converter overrides ConvertValueToString(Object, Type) so that each parameter is serialized to JSON using the default DataContractJsonSerializer and a JSON XML Writer configured to use the UTF-8 encoding. null parameters are returned as null.


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
