BasicHttpBinding Class

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Represents a binding that a Silverlight 5 client can use to configure endpoints that can communicate with ASMX-based Web services and other services that conform to the WS-I Basic Profile 1.1.

The BasicHttpBinding type exposes the following members.

Constructors

Properties

	Name	Description
	CloseTimeout	Gets or sets the interval of time provided for a connection to close before the transport raises an exception. (Inherited from Binding.)
	EnableHttpCookieContainer	Gets or sets a value that indicates whether the [T:P:System.ServiceModel.BasicHttpBinding] will include the HttpCookieContainerBindingElement.
	EnvelopeVersion	Gets the version of SOAP that is used for messages that are processed by this binding.
	MaxBufferSize	Gets or sets the maximum size for a buffer that receives messages from the channel.
	MaxReceivedMessageSize	Gets or sets the maximum size for a message that can be received on a channel configured with this binding.
	MessageVersion	Gets the message version used by clients and services configured with the binding. (Inherited from Binding.)
	Name	Gets or sets the name of the binding. (Inherited from Binding.)
	Namespace	Gets or sets the XML namespace of the binding. (Inherited from Binding.)
	OpenTimeout	Gets or sets the interval of time provided for a connection to open before the transport raises an exception. (Inherited from Binding.)
	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. (Inherited from Binding.)
	Scheme	Gets the URI transport scheme for the channels and listeners that are configured with this binding. (Overrides Binding.Scheme.)
	Security	Gets the type of security used with this binding.
	SendTimeout	Gets or sets the interval of time provided for a write operation to complete before the transport raises an exception. (Inherited from Binding.)
	TextEncoding	Gets or sets the character encoding that is used for the message text.
	TransferMode	Gets or sets a value that indicates whether messages are sent buffered or streamed.

Methods

	Name	Description
	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. (Inherited from Binding.)
	BuildChannelFactory<TChannel>(array<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. (Inherited from Binding.)
	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. (Inherited from Binding.)
	CanBuildChannelFactory<TChannel>(array<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. (Inherited from Binding.)
	CreateBindingElements	Returns an ordered collection of binding elements contained in the current binding. (Overrides Binding.CreateBindingElements().)
	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. (Inherited from Binding.)
	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.)

Remarks

The BasicHttpBinding uses HTTP as the transport for sending SOAP 1.1 messages. A service can use this binding to expose endpoints that conform to WS-I BP 1.1, such as those that ASMX clients access. Similarly, a client can use the BasicHttpBinding to communicate with services that expose endpoints that conform to WS-I BP 1.1, such as ASMX Web services or Windows Communication Foundation (WCF) services configured with the BasicHttpBinding.

Security is turned off by default, but can be added by setting the BasicHttpSecurityMode to a value other than None in the BasicHttpBinding(BasicHttpSecurityMode) constructor. It uses a "Text" message encoding and UTF-8 text encoding by default.
