BaseChannelSinkWithProperties Class
Provides a base implementation for channel sinks that want to expose a dictionary interface to their properties.

Assembly: mscorlib (in mscorlib.dll)
The BaseChannelSinkWithProperties type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | BaseChannelSinkWithProperties | Initializes a new instance of the BaseChannelSinkWithProperties class. |
| Name | Description | |
|---|---|---|
![]() | Count | Gets the number of properties associated with the channel object. (Inherited from BaseChannelObjectWithProperties.) |
![]() | IsFixedSize | Gets a value that indicates whether the number of properties that can be entered into the channel object is fixed. (Inherited from BaseChannelObjectWithProperties.) |
![]() | IsReadOnly | Gets a value that indicates whether the collection of properties in the channel object is read-only. (Inherited from BaseChannelObjectWithProperties.) |
![]() | IsSynchronized | Gets a value that indicates whether the dictionary of channel object properties is synchronized. (Inherited from BaseChannelObjectWithProperties.) |
![]() | Item | When overridden in a derived class, gets or sets the property that is associated with the specified key. (Inherited from BaseChannelObjectWithProperties.) |
![]() | Keys | When overridden in a derived class, gets a ICollection of keys that the channel object properties are associated with. (Inherited from BaseChannelObjectWithProperties.) |
![]() | Properties | Gets a IDictionary of the channel properties associated with the channel object. (Inherited from BaseChannelObjectWithProperties.) |
![]() | SyncRoot | Gets an object that is used to synchronize access to the BaseChannelObjectWithProperties. (Inherited from BaseChannelObjectWithProperties.) |
![]() | Values | Gets a ICollection of the values of the properties associated with the channel object. (Inherited from BaseChannelObjectWithProperties.) |
| Name | Description | |
|---|---|---|
![]() | Add | Throws a NotSupportedException. (Inherited from BaseChannelObjectWithProperties.) |
![]() | Clear | Throws a NotSupportedException. (Inherited from BaseChannelObjectWithProperties.) |
![]() | Contains | Returns a value that indicates whether the channel object contains a property that is associated with the specified key. (Inherited from BaseChannelObjectWithProperties.) |
![]() | CopyTo | Throws a NotSupportedException. (Inherited from BaseChannelObjectWithProperties.) |
![]() | 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.) |
![]() | GetEnumerator | Returns a IDictionaryEnumerator that enumerates over all the properties associated with the channel object. (Inherited from BaseChannelObjectWithProperties.) |
![]() | 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.) |
![]() | Remove | Throws a NotSupportedException. (Inherited from BaseChannelObjectWithProperties.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
![]() ![]() | IEnumerable::GetEnumerator | Infrastructure. Returns a IEnumerator that enumerates over all the properties that are associated with the channel object. (Inherited from BaseChannelObjectWithProperties.) |
Channel sinks provide a plug-in point that allows access to the underlying messages that are flowing through the channel as well as the stream that is used by the transport mechanism to send messages to a remote object. Channel sinks are linked together in a chain of channel sink providers, and all channel messages flow through this chain of sinks before the message is serialized and transported.
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 InheritorsWhen you inherit from BaseChannelSinkWithProperties, you must implement the Keys property and the Item property.
