ContextBoundObject Class

Defines the base class for all context-bound classes.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

[SerializableAttribute]
[ComVisibleAttribute(true)]
public abstract class ContextBoundObject : MarshalByRefObject

The ContextBoundObject type exposes the following members.

  NameDescription
Protected methodContextBoundObjectInstantiates an instance of the ContextBoundObject class.

  NameDescription
Public methodCreateObjRefCreates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetLifetimeServiceRetrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodInitializeLifetimeServiceObtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Protected methodMemberwiseClone()Creates a shallow copy of the current Object. (Inherited from Object.)
Protected methodMemberwiseClone(Boolean)Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Objects that reside in a context and are bound to the context rules are called context-bound objects. A context is a set of properties or usage rules that define an environment where a collection of objects resides. The rules are enforced when the objects are entering or leaving a context. Objects that are not context-bound are called agile objects.

Contexts are created during object activation. A new object is placed into an existing context or into a new context created using the attributes included in the metadata of the type. Context-bound classes are marked with a ContextAttribute that provides the usage rules. The context properties that can be added include policies regarding synchronization and transactions.

Notes to Implementers

The current version of the common language runtime does not support generic ContextBoundObject types or nongeneric ContextBoundObject types that have generic methods. Attempting to create an instance of such a type causes a TypeLoadException.

For more information, see the Advantages and Limitations of Generics topic.
