Namespace:  System.Runtime.Serialization.Formatters.Soap
Assembly:  System.Runtime.Serialization.Formatters.Soap (in System.Runtime.Serialization.Formatters.Soap.dll)

public Object Deserialize(
	Stream serializationStream
)

Parameters

serializationStream
Type: System.IO.Stream

The stream that contains the data to deserialize.

Return Value

Type: System.Object
The top object of the deserialized graph (root).

Implements

IFormatter.Deserialize(Stream)

ExceptionCondition
ArgumentNullException

serializationStream is null.

For successful deserialization, the current position in the stream must be at the beginning of the object graph.
