Web API, How to Override JSON Serialization For Specific DataType?

Question

I have bunch of TimeSpan properties in response from Web API. By default JSON serializer includes decimal values of seconds as well in response. E.G. 08:30:00.000909 These micro-seconds values are not needed in response.

Is it possible to override JSON serializer so that it could skip out milli/micro-second components in the serialized JSON response?

Have you looked at the callbacks available during serialization/deserialization ? Perhaps you can parse out the data you don't want using these callbacks ? newtonsoft.com/json/help/html/SerializationCallbacks.htm — Francis Ducharme

You may want to use custom serializer for your Web API http://tinymission.com/post/custom-serialization-for-json-properties-in-web-api

Or before you convert your DTO to Model, you can use Custom Date and Time Format Strings.
