JavaScriptSerializer.Deserialize Method (String, Type)

.NET Framework 4.6 and 4.5

Converts a JSON-formatted string to an object of the specified type.

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

'Declaration
Public Function Deserialize ( _
	input As String, _
	targetType As Type _
) As Object

Parameters

input
Type: System.String

The JSON string to deserialize.

targetType
Type: System.Type

The type of the resulting object.

Return Value

Type: System.Object
The deserialized object.

ExceptionCondition
ArgumentNullException

input is Nothing.

ArgumentException

The length of input exceeds the value of MaxJsonLength.

-or-

The recursion limit defined by RecursionLimit was exceeded.

-or-

input contains an unexpected character sequence.

-or-

input is a dictionary type and a non-string key value was encountered.

-or-

input includes member definitions that are not available on the target type.

InvalidOperationException

input contains a "__type" property that indicates a custom type, but the type resolver that is currently associated with the serializer cannot find a corresponding managed type.

-or-

input contains a "__type" property that indicates a custom type, but the result of deserializing the corresponding JSON string cannot be assigned to the expected target type.

-or-

input contains a "__type" property that indicates either Object or a non-instantiable type (for example, an abstract type or an interface).

-or-

An attempt was made to convert a JSON array to an array-like managed type that is not supported for use as a JSON deserialization target.

-or-

It is not possible to convert input to the target type.

This deserialization method does not try to cast the root of the object graph to a specific type, the way that the Deserialize method does.
