OperationFlow Enumeration
Specifies the type of transmission an endpoint of the XML Web service can support.
Assembly: System.Web.Services (in System.Web.Services.dll)
| Member name | Description | |
|---|---|---|
| None | Indicates that the endpoint of the XML Web service receives no transmissions. | |
| OneWay | Indicates that the endpoint of the XML Web service receives a message. | |
| Notification | Indicates that the endpoint of the XML Web service sends a message. | |
| RequestResponse | Indicates that the endpoint of the XML Web service receives a message, then sends a correlated message. | |
| SolicitResponse | Indicates that the endpoint of the XML Web service sends a message, then receives a correlated message. |
Although request-response or solicit-response operations are logically correlated in the Web Services Description Language (WSDL) document, the concrete correlation information will be specified by a binding. For example, the request and response messages can be exchanged as part of one or two actual HTTP transmissions.
The following sample demonstrates the use of the OperationFlow enumeration.
