Remarks

BaseChannelObjectWithProperties is the base class for BaseChannelWithProperties and BaseChannelSinkWithProperties.

BaseChannelWithProperties and BaseChannelSinkWithProperties can be used as the base classes for channels and channel sinks that provide named properties.

BaseChannelObjectWithProperties handles the complex task of asking a channel object for its properties.

This class makes a link demand and an inheritance demand at the class level. A SecurityException is thrown when either the immediate caller or the derived class does not have infrastructure permission. For details about security demands, see Link Demands and Inheritance Demands.

Notes to Inheritors

When you inherit from BaseChannelObjectWithProperties, you must override the Keys property and the Item[Object] property.

Constructors

BaseChannelObjectWithProperties() BaseChannelObjectWithProperties() BaseChannelObjectWithProperties() BaseChannelObjectWithProperties()

Initializes a new instance of the BaseChannelObjectWithProperties class.

Properties

Count Count Count Count

Gets the number of properties associated with the channel object.

IsFixedSize IsFixedSize IsFixedSize IsFixedSize

Gets a value that indicates whether the number of properties that can be entered into the channel object is fixed.

IsReadOnly IsReadOnly IsReadOnly IsReadOnly

Gets a value that indicates whether the collection of properties in the channel object is read-only.

IsSynchronized IsSynchronized IsSynchronized IsSynchronized

Gets a value that indicates whether the dictionary of channel object properties is synchronized.

Item[Object] Item[Object] Item[Object] Item[Object]

When overridden in a derived class, gets or sets the property that is associated with the specified key.

Keys Keys Keys Keys

When overridden in a derived class, gets a ICollection of keys that the channel object properties are associated with.

Properties Properties Properties Properties

Gets a IDictionary of the channel properties associated with the channel object.

SyncRoot SyncRoot SyncRoot SyncRoot

Gets an object that is used to synchronize access to the BaseChannelObjectWithProperties.

Values Values Values Values

Gets a ICollection of the values of the properties associated with the channel object.
