SoapMessage.EnsureOutStage Method

When overridden in a derived class, asserts that the current SoapMessageStage stage is a stage where out parameters are available.

Namespace:  System.Web.Services.Protocols
Assembly:  System.Web.Services (in System.Web.Services.dll)

protected abstract void EnsureOutStage()


Out parameters are not available.

The asserted stage is different for XML Web service clients and XML Web service methods. An XML Web service method's out parameters are available prior to the SOAP response serialization process in the BeforeSerialize stage. In an XML Web service client, the out parameters are available after the SOAP response deserialization process in the AfterDeserialize stage.

EnsureOutStage can be called during any SoapMessageStage, however an InvalidOperationException is thrown when out parameters are not available.
