how to force netwtonsoft json serializer to serialize datetime property to string?

I am using Newtonsoft's Json when i serialze a date time property i get the json r开发者_运维技巧esponse as:

..."CreatedOn":"\/Date(1317303882420+0500)\/",...

i want it to be in simple string as

..."createdOn": "2011-05-05 14:03:07", ...

while my class property is DateTime, how can i force to serialze it as string, as we can add attribute to change the property name as

  [JsonProperty("id")]
        public int ProductID { get; set; }

is there a similar way to force a DateTime property to serialize to string??

From a post made by James Newton-King on StackOverflow, it looks like you can do this.

string isoJson = JsonConvert.SerializeObject(this, new IsoDateTimeConverter());
// {"Details":"Application started.","LogDate":"2009-02-15T00:00:00Z"}

Also here is the documentation on Json.NET and dates: Serializing Dates in JSON

Here is an example of using the DateTimeFormat property to customize the output:

return JsonConvert.SerializeObject(this, Formatting.None, new IsoDateTimeConverter() { DateTimeFormat = "yyyy-MM-dd HH:mm:ss" });
