Represents an attribute indicating that a service operation is logically a retrieval operation and that it can be called by the WCF REST programming model.
Assembly: System.ServiceModel.Web (in System.ServiceModel.Web.dll)
Thetype exposes the following members.
|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.|
|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||Gets and sets the Uniform Resource Identifier (URI) template for the service operation.|
|Equals||Infrastructure. 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||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.)|
|_Attribute::GetIDsOfNames||Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)|
|_Attribute::GetTypeInfo||Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)|
|_Attribute::GetTypeInfoCount||Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)|
|_Attribute::Invoke||Provides access to properties and methods exposed by an object. (Inherited from Attribute.)|
|IOperationBehavior::AddBindingParameters||Implements the AddBindingParameters(OperationDescription, BindingParameterCollection) method.|
|IOperationBehavior::ApplyClientBehavior||Implements the ApplyClientBehavior(OperationDescription, ClientOperation) method.|
|IOperationBehavior::ApplyDispatchBehavior||Implements the ApplyDispatchBehavior(OperationDescription, DispatchOperation) method.|
|IOperationBehavior::Validate||Implements the Validate(OperationDescription) method.|
The attribute is applied to a service operation in addition to the OperationContractAttribute and associates the operation with a UriTemplate as well as the HTTP protocol Get verb. The association with HTTP Get verb means that the operation is used to retrieve information from the service. The attribute is a passive operation behavior (the IOperationBehavior methods do nothing) that adds metadata to the operation description. Applying the attribute to a service operation has no effect unless a behavior that is looking for this metadata in the operation description (such as WebHttpBehavior) is added to the service's behavior collection.
Service operations with the attribute applied should be logical retrieval operations. The HTTP GET method is associated with all operations marked with the attribute.
