ContextAttribute Class

This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

Provides the default implementations of the IContextAttribute and IContextProperty interfaces.

Namespace:  System.Runtime.Remoting.Contexts
Assembly:  mscorlib (in mscorlib.dll)

[SerializableAttribute]
[AttributeUsageAttribute(AttributeTargets.Class)]
[ComVisibleAttribute(true)]
[SecurityPermissionAttribute(SecurityAction.InheritanceDemand, Flags = SecurityPermissionFlag.Infrastructure)]
public class ContextAttribute : Attribute, 
	IContextAttribute, IContextProperty

The ContextAttribute type exposes the following members.

  NameDescription
Public methodContextAttributeInfrastructure. Creates an instance of the ContextAttribute class with the specified name.
Top

  NameDescription
Public propertyNameInfrastructure. Gets the name of the context attribute.
Public propertyTypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)
Top

  NameDescription
Public methodEqualsInfrastructure. Returns a Boolean value indicating whether this instance is equal to the specified object. (Overrides Attribute.Equals(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 methodFreezeInfrastructure. Called when the context is frozen.
Public methodGetHashCodeInfrastructure. Returns the hashcode for this instance of ContextAttribute. (Overrides Attribute.GetHashCode().)
Public methodGetPropertiesForNewContextInfrastructure. Adds the current context property to the given message.
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIsContextOKInfrastructure. Returns a Boolean value indicating whether the context parameter meets the context attribute's requirements.
Public methodIsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public methodIsNewContextOKInfrastructure. Returns a Boolean value indicating whether the context property is compatible with the new context.
Public methodMatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
Top

  NameDescription
Protected fieldAttributeNameInfrastructure. Indicates the name of the context attribute.
Top

  NameDescription
Explicit interface implemetationPrivate method_Attribute.GetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.InvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

The ContextAttribute class is the root for all context attributes. Simple Context class properties can be derived from ContextAttribute with the context attribute and the context property being in the class. For more specialized or more sophisticated needs, the context attribute can derive from ContextAttribute and the context property can be split into a separated class. For more information about using attributes, see Extending Metadata Using Attributes.

Notes to Inheritors

The Name property must not be overridden in any user derived class. The current Equals and GetHashCode methods depend on the default functionality. To provide advanced behavior for a class extending the ContextAttribute class and override the Name property, you also have to override the default implementation of the Equals and GetHashCode methods.
