Remarks

Warning: BinaryFormatter is insecure and can't be made secure. For more information, see the BinaryFormatter security guide. The in-box implementation of BinaryFormatter was removed in .NET 9. For more information, see BinaryFormatter migration guide.

Constructors

BinaryFormatter()	Initializes a new instance of the BinaryFormatter class with default values.
BinaryFormatter(ISurrogateSelector, StreamingContext)	Initializes a new instance of the BinaryFormatter class with a given surrogate selector and streaming context.

Properties

AssemblyFormat	Gets or sets the behavior of the deserializer with regards to finding and loading assemblies.
Binder	(Insecure) Gets or sets an object of type SerializationBinder that controls the binding of a serialized object to a type.
Context	Gets or sets the StreamingContext for this formatter.
FilterLevel	Gets or sets the TypeFilterLevel of automatic deserialization the BinaryFormatter performs.
SurrogateSelector	Gets or sets a ISurrogateSelector that controls type substitution during serialization and deserialization.
TypeFormat	Gets or sets the format in which type descriptions are laid out in the serialized stream.

Methods

Deserialize(Stream)	Obsolete. Deserializes the specified stream into an object graph.
Deserialize(Stream, HeaderHandler)	Deserializes the specified stream into an object graph. The provided HeaderHandler handles any headers in that stream.
DeserializeMethodResponse(Stream, HeaderHandler, IMethodCallMessage)	Deserializes a response to a remote method call from the provided Stream.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
Serialize(Stream, Object)	Obsolete. Serializes the object, or graph of objects with the specified top (root), to the given stream.
Serialize(Stream, Object, Header[])	Serializes the object, or graph of objects with the specified top (root), to the given stream attaching the provided headers.
ToString()	Returns a string that represents the current object. (Inherited from Object)
UnsafeDeserialize(Stream, HeaderHandler)	Deserializes the specified stream into an object graph. The provided HeaderHandler handles any headers in that stream.
UnsafeDeserializeMethodResponse(Stream, HeaderHandler, IMethodCallMessage)	Deserializes a response to a remote method call from the provided Stream.
