JavaScriptSerializer.Serialize Method (Object, StringBuilder)


Serializes an object and writes the resulting JSON string to the specified StringBuilder object.

Namespace:   System.Web.Script.Serialization
Assembly:  System.Web.Extensions (in System.Web.Extensions.dll)

Public Sub Serialize (
	obj As Object,
	output As StringBuilder


Type: System.Object

The object to serialize.

Type: System.Text.StringBuilder

The StringBuilder object that is used to write the JSON string.

Exception Condition

The resulting JSON string exceeds the value of MaxJsonLength.


obj contains a circular reference. A circular reference occurs when a child object has a reference to a parent object, and the parent object has a reference to the child object.


The recursion limit defined by RecursionLimit was exceeded.


output is null.

When the JavaScriptSerializer instance is serializing a type for which a custom converter is registered, the serializer calls the Serialize method to obtain the dictionary of name/value pairs that will be converted to a JSON string.

The Serialize method can also throw exceptions if the object graph is too complex, or if registered instances of JavaScriptConverter have caused converter recursion.
