BinaryFormatter::UnsafeDeserialize Method
Deserializes the specified stream into an object graph. The provided HeaderHandler handles any headers in that stream.
Assembly: mscorlib (in mscorlib.dll)
[ComVisibleAttribute(false)] public: Object^ UnsafeDeserialize( Stream^ serializationStream, HeaderHandler^ handler )
Parameters
- serializationStream
- Type: System.IO::Stream
The stream from which to deserialize the object graph.
- handler
- Type: System.Runtime.Remoting.Messaging::HeaderHandler
The HeaderHandler that handles any headers in the serializationStream. Can be nullptr.
Return Value
Type: System::ObjectThe deserialized object or the top object (root) of the object graph.
| Exception | Condition |
|---|---|
| ArgumentNullException | The serializationStream is nullptr. |
| SerializationException | The serializationStream supports seeking, but its length is 0. |
| SecurityException | The caller does not have the required permission. |
Headers are used only for specific remoting applications.
This method uses SecurityAction::LinkDemand to prevent it from being called from untrusted code; only the immediate caller is required to have SecurityPermissionAttribute::SerializationFormatter permission. Do not use this method if your code can be called from partially trusted code. In partially trusted scenarios, use Deserialize instead. In full trust scenarios, UnsafeDeserialize provides better performance than Deserialize.
For successful deserialization, the current position in the stream must be at the beginning of the object graph.
- SecurityPermission
To provide serialization services. Associated enumeration: SecurityPermissionFlag::SerializationFormatter.
