public:
 override System::String ^ ConvertValueToString(System::Object ^ parameter, Type ^ parameterType);

public override string ConvertValueToString (object parameter, Type parameterType);

override this.ConvertValueToString : obj * Type -> string

Public Overrides Function ConvertValueToString (parameter As Object, parameterType As Type) As String

Parameters

parameter: Object

The parameter value to convert.

parameterType: Type

The Type of the parameter to serialize.

Returns

String

The JSON query string parameter serialization of the CLR type. null is returned if the parameter is null.

Examples

Consider the following operation.

[WebGet]  
[OperationContract] public int GetOptionQuote(string ticker, DateTime dte, Option opt);

This operation produces a URL that is a URL-encoded version of the following.

http://localhost/quote.svc/GetOptionQuote?ticker="MSFT"&dte="\/Date(50067823)\/"&opt={"type":"call","strikePrice":"35"}

Remarks

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. Unlike its base type, this converter can handle any type adhering to the Data Contract model.
