.NET Framework (current version)

Other Versions

Represents an attribute indicating that a service operation is logically an invoke operation and that it can be called by the WCF REST programming model.

Syntax

C++

[AttributeUsageAttribute(AttributeTargets::Method)]
public ref class WebInvokeAttribute sealed : Attribute, IOperationBehavior

Constructors

	Name	Description
	WebInvokeAttribute()	Initializes a new instance of the WebGetAttribute class.

Properties

	Name	Description
	BodyStyle	Gets and sets the body style of the messages that are sent to and from the service operation.
	IsBodyStyleSetExplicitly	Gets the IsBodyStyleSetExplicitly property.
	IsRequestFormatSetExplicitly	Gets the IsRequestFormatSetExplicitly property.
	IsResponseFormatSetExplicitly	Gets the IsResponseFormatSetExplicitly property.
	Method	Gets and sets the protocol (for example HTTP) method the service operation responds to.
	RequestFormat	Gets and sets the RequestFormat property.
	ResponseFormat	Gets and sets the ResponseFormat property.
	TypeId	When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)
	UriTemplate	The Uniform Resource Identifier (URI) template for the service operation.

Methods

	Name	Description
	Equals(Object^)	This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)
	GetHashCode()	Returns the hash code for this instance.(Inherited from Attribute.)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	IsDefaultAttribute()	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)
	Match(Object^)	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)
	ToString()	Returns a string that represents the current object.(Inherited from Object.)

Explicit Interface Implementations

	Name	Description
	_Attribute::GetIDsOfNames(Guid%, IntPtr, UInt32, UInt32, IntPtr)	Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)
	_Attribute::GetTypeInfo(UInt32, UInt32, IntPtr)	Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)
	_Attribute::GetTypeInfoCount(UInt32%)	Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)
	_Attribute::Invoke(UInt32, Guid%, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)	Provides access to properties and methods exposed by an object.(Inherited from Attribute.)
	IOperationBehavior::AddBindingParameters(OperationDescription^, BindingParameterCollection^)	Implements the AddBindingParameters(OperationDescription^, BindingParameterCollection^) method.
	IOperationBehavior::ApplyClientBehavior(OperationDescription^, ClientOperation^)	Implements the ApplyClientBehavior(OperationDescription^, ClientOperation^) method.
	IOperationBehavior::ApplyDispatchBehavior(OperationDescription^, DispatchOperation^)	Implements the ApplyDispatchBehavior(OperationDescription^, DispatchOperation^) method.
	IOperationBehavior::Validate(OperationDescription^)	Implements the Validate(OperationDescription^) method.

The WebInvokeAttribute attribute is applied to a service operation in addition to the OperationContractAttribute and associates the operation with a UriTemplate as well as an underlying transport verb that represents an invocation (for example, HTTP POST, PUT, or DELETE). The WebInvokeAttribute attribute is a passive operation behavior (the IOperationBehavior methods do nothing) that adds metadata to the operation description. Applying the WebInvokeAttribute attribute to a service operation has no effect unless a behavior that looks for this metadata in the operation description (such as WebHttpBehavior) is added to the service's behavior collection. The WebInvokeAttribute determines what HTTP method that a service operation responds to. By default, all methods that have the WebInvokeAttribute applied respond to POST requests. The Method property allows you to specify a different HTTP method. If you want a service operation to respond to GET, use the WebGetAttribute instead.
