Question

Within an ASP.NET application, I’d like to serialize a collection of plain-old-CLR-objects (POCO) to a JSON string, which will then be sent down to the client as part of a web response.

Is there a light-weight C# library that does this?

Try DataContractJsonSerializer:

Serializes objects to the JavaScript
Object Notation (JSON) and
deserializes JSON data to objects.

Use the DataContractJsonSerializer
class to serialize instances of a type
into a JSON document and to
deserialize a JSON document into an
instance of a type. For example, you
can create a type named Person with
properties that contain essential
data, such as a name and address. You
can then create and manipulate an
instance of the Person class and write
all of its property values in a JSON
document for later retrieval. This
JSON document can later be
deserialized into the Person class or
another class with an equivalent data
contract.
