ObjectStateFormatter.Deserialize Method (String)

Deserializes an object state graph from its serialized base64-encoded string form.

Namespace:  System.Web.UI
Assembly:  System.Web (in System.Web.dll)

public Object Deserialize(
	string inputString


Type: System.String
A string that the ObjectStateFormatter deserializes into an initialized object.

Return Value

Type: System.Object
An object that represents a deserialized object state graph.


The specified inputString is null or has a Length of 0.


The serialized data is invalid.


The machine authentication code (MAC) validation check that is performed when deserializing view state fails.

Any object state graph that is serialized with the Serialize method can be deserialized with the Deserialize method. The Deserialize(String) method is used to restore an object state graph stored in base64-encoded string form.

The following code example demonstrates how to implement a method that deserializes a base64-encoded string and returns an ICollection collection of property settings. This code example relies on the property settings having been serialized with the ObjectStateFormatter class, as shown in the Serialize(Object) method.

private ICollection LoadControlProperties (string serializedProperties) {

    ICollection controlProperties = null;

    // Create an ObjectStateFormatter to deserialize the properties.
    ObjectStateFormatter formatter = new ObjectStateFormatter();

    // Call the Deserialize method.
    controlProperties = (ArrayList) formatter.Deserialize(serializedProperties);

    return controlProperties;
