Allows users to control class loading and mandate what class to load.
Assembly: mscorlib (in mscorlib.dll)
Thetype exposes the following members.
|BindToName||When overridden in a derived class, controls the binding of a serialized object to a type.|
|BindToType||When overridden in a derived class, controls the binding of a serialized object to a type.|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as a hash function for a particular type. (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.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
During serialization, a formatter transmits the information required to create an instance of an object of the correct type and version. This information generally includes the full type name and assembly name of the object. The assembly name includes the name, version, and strong name (see Strong-Named Assemblies) hash of the assembly. By default, deserialization uses this information to create an instance of an identical object (with the exception of any assembly loading restricted by the security policy). Some users need to control which class to load, either because the class has moved between assemblies or a different version of the class is required on the server and client.
can also be used for security. There might be some security exploits when you are trying to deserialize some data from an untrusted source. The binder gives you an opportunity to inspect what types are being loaded in your application domain. You can then either maintain list of denied types or a list of allowed types and restrict which types are being loaded and instantiated. In addition you should be mindful of what information is being put out on the wire, you may want to secure (use transport or message security) when sending type names or other data on the wire.
Only use if you are completely sure of what information is being serialized. Malicious types can cause unexpected behavior.
This is an abstract base class. All binders extend this class.Notes to Inheritors
When you inherit from , you must override the following member: BindToType.
