Contains the binding elements that specify the protocols, transports, and message encoders used for communication between clients and services.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
Thetype exposes the following members.
|CloseTimeout||Gets or sets the interval of time provided for a connection to close before the transport raises an exception.|
|MessageVersion||Gets the message version used by clients and services configured with the binding.|
|Name||Gets or sets the name of the binding.|
|Namespace||Gets or sets the XML namespace of the binding.|
|OpenTimeout||Gets or sets the interval of time provided for a connection to open before the transport raises an exception.|
|ReceiveTimeout||Gets or sets the interval of time that a connection can remain inactive, during which no application messages are received, before it is dropped.|
|Scheme||When implemented in a derived class, sets the URI scheme that specifies the transport used by the channel factories that are built by the bindings.|
|SendTimeout||Gets or sets the interval of time provided for a write operation to complete before the transport raises an exception.|
|BuildChannelFactory<TChannel>(BindingParameterCollection)||Builds the channel factory stack on the client that creates a specified type of channel and that satisfies the features specified by a collection of binding parameters.|
|BuildChannelFactory<TChannel>(Object)||Builds the channel factory stack on the client that creates a specified type of channel and that satisfies the features specified by an object array.|
|CanBuildChannelFactory<TChannel>(BindingParameterCollection)||Returns a value that indicates whether the current binding can build a channel factory stack on the client that satisfies the collection of binding parameters specified.|
|CanBuildChannelFactory<TChannel>(Object)||Returns a value that indicates whether the current binding can build a channel factory stack on the client that satisfies the requirements specified by an object array.|
|CreateBindingElements||When overridden in a derived class, creates a collection that contains the binding elements that are part of the current binding.|
|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 the Object is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetProperty<T>||Returns a typed object requested, if present, from the appropriate layer in the binding stack.|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
Represents a collection of binding elements, each of which describes an aspect of how an endpoint communicates with other endpoints and that are built, consistently, into a channel factory on the client. A binding contains a collection of binding elements that correspond to protocol channels and transport channels, which also specify message encoders. There can be any number of binding elements for protocol channels but one and only one binding element for each the transport and message encoder. The transport and encoding binding elements are required. Because an encoding is required for each binding, if an encoding is not specified, Windows Phone adds a default encoding for you. The default is Text/XML for the HTTP transport.
The following table summarizes the required layers.
Text, Binary, MTOM, Custom
Each binding element provides the specification for building a channel factory for a Windows Phone client. When the channel factory stack is constructed, for example, there is one channel factory in the stack for each binding element in the binding. Consistency on the client and service is critical for establishing the channel-based connection between these endpoints. Each factory on the client processes the sending and accepting of the corresponding channels in the channel stack, and these channels, once constructed, can send and receive the messages used to communicate with a service.
Each instance of a has a Name and Namespace that together uniquely identify it in the metadata of the service. If no name or namespace is specified, Windows Phone adds a default values for you. The default Name is null and the default Namespace is http://tempuri.org/. Note that this user name for the binding is distinct from the specification of the protocol name, which is specified by the Scheme property. If you want to add more HTTP bindings, for example, you can name them whatever you want and set all of their schemes to "http". There is no inherent application or machine dispatch based on the Scheme. So you avoid the common problem of being unable to register additional handlers for well-known protocols. You can also easily work with multiple versions of a binding side-by-side by giving each version a different name.
The class implements the IDefaultCommunicationTimeouts interface to mitigate Denial of Service (DOS) attacks that rely on tying up resources for extended intervals of time. The implementation specifies the communication time-out values for opening and closing connections and for the reading and writing operations associated with receiving and sending messages. The properties used to get and set these time-outs and their default value operations are summarized in the following table.
When you create a binding by inheriting from , you must override CreateBindingElements.
