With my need to exchange data between a ASP.NET and PHP web applications, I decided to use JSON. The .NET team did a good job by integrating JSON de/serialization into the language (NET 3.5) but they decided not to follow JSON specifications for some good reasons. Serializing an object that has a DateTime property will insert a string that won’t be understood by json_decode of PHP.

On the site of JSON, there is no such thing as a date type.  I have taken the ISO 8601 path which is my preferred date format (MySQL and Swedish Locale standard)

Consider the following class:

[code lang="C#"]
[DataContract]
public class Person
{
[DataMember]
public DateTime DateOfBirth { set; get; }
[DataMember]
public string Names { set; get; }
}
[/code]

By Serializing it you will get something like

[code]

{"DateOfBirth" : "\/Date(1210408872000+0200)\/", "Names" : "Kavuna ka Lyaziga"}

[/code]

That Date is not defined as a JSON type. In case your JSON will be used directly by JavaScript or .NET (C#, VB) you will not need to write extra codes.
