Examples

The following example shows how to use the WebGetAttribute attribute.

[ServiceContract]
public interface ICalculator
{
    [OperationContract]
    [WebGet]
    long Add(long x, long y);

    [OperationContract]
    [WebGet(UriTemplate = "Sub?x={x}&y={y}")]
    long Subtract(long x, long y);

    [OperationContract]
    [WebGet(UriTemplate = "Mult?x={x}&y={y}", BodyStyle = WebMessageBodyStyle.Bare)]
    long Multiply(long x, long y);

    [OperationContract]
    [WebGet(UriTemplate = "Div?x={x}&y={y}", RequestFormat = WebMessageFormat.Xml)]
    long Divide(long x, long y);

    [OperationContract]
    [WebGet(ResponseFormat= WebMessageFormat.Json)]
    long Mod(long x, long y);
}
<ServiceContract()> _
Public Interface ICalculator
    <OperationContract()> _
    <WebGet()> _
    Function Add(ByVal x As Long, ByVal y As Long) As Long

    <OperationContract()> _
    <WebGet(UriTemplate:="Sub?x={x}&y={y}")> _
    Function Subtract(ByVal x As Long, ByVal y As Long) As Long

    <OperationContract()> _
    <WebGet(UriTemplate:="Mult?x={x}&y={y}", BodyStyle:=WebMessageBodyStyle.Bare)> _
    Function Multiply(ByVal x As Long, ByVal y As Long) As Long

    <OperationContract()> _
    <WebGet(UriTemplate:="Div?x={x}&y={y}", RequestFormat:=WebMessageFormat.Xml)> _
    Function Divide(ByVal x As Long, ByVal y As Long) As Long

    <OperationContract()> _
    <WebGet(ResponseFormat:=WebMessageFormat.Json)> _
    Function Modulo(ByVal x As Long, ByVal y As Long) As Long
End Interface

Remarks

The WebGetAttribute 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 WebGetAttribute attribute is a passive operation behavior (the IOperationBehavior methods do nothing) that adds metadata to the operation description. Applying the WebGetAttribute 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 WebGetAttribute attribute applied should be logical retrieval operations. The HTTP GET method is associated with all operations marked with the WebGetAttribute attribute.
