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)

Syntax

Visual Basic (Declaration)

<SerializableAttribute> _
<ComVisibleAttribute(True)> _
<AttributeUsageAttribute(AttributeTargets.Class)> _
<SecurityPermissionAttribute(SecurityAction.LinkDemand, Flags := SecurityPermissionFlag.Infrastructure)> _
<SecurityPermissionAttribute(SecurityAction.InheritanceDemand, Flags := SecurityPermissionFlag.Infrastructure)> _
Public Class ContextAttribute _
    Inherits Attribute _
    Implements IContextAttribute, IContextProperty

Visual Basic (Usage)

Dim instance As ContextAttribute

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

Visual C++

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

JScript

public class ContextAttribute extends Attribute implements IContextAttribute, IContextProperty

Remarks

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.
