JavaScript Object Notation (JSON)

JavaScript Object Notation (JSON)
To allow for a more efficient transfer of data and classes between web applications and
web services, ASP.NET AJAX supports the JavaScript Object Notation (JSON) format. It is
lighter weight than XML (Extensible Markup Language)/SOAP (Simple Object Access
Protocol), and delivers a more consistent experience because of the implementation
differences of XML/SOAP by the various browsers.
JSON is a text-based data-interchange format that represents data as a set of ordered
name/value pairs. As an example, take a look at the following class definition, which
stores a person’s name and age:

public class MyDetails
{
string FirstName;
string LastName;
int Age;

}

A two-element array of this object is represented as follows:
{ MyDetails : [ { “FirstName” : “Landon”, “LastName” : “Donovan”, “Age” : “22”}
{ “FirstName” : “John”, “LastName” : “Grieb”, “Age” : “46”}
]
}
