help! Boss, please take a look, the problem that has troubled for a long time (call webservice)

yhb2199

Error message:
An unhandled "System.InvalidOperationException" type exception appears in system.web.services.dll.

Additional information: The method PresenceSupplierService.getMyWatchers cannot be reflected.
===============================
PresenceSupplierService.dll was generated using the rendered wsdl and added to the project's reference along with System.Web.Services.dll, the relevant code:
getMyWatchers y_object = new getMyWatchers ();
y_object.presentity = "sip: kk@192.168.2.251: 50611";
PresenceSupplierService ps = new PresenceSupplierService (); // This step is suggested
string [] result = ps.getMyWatchers (y_object);
===============================
When I call the PresenceNotificationService in a similar way, it is normal (the service is sag upstream to the sp side, and supplierservice is the sag downstream of the sp side); the younger first came to .net, for advice and advice

Try to regenerate the proxy class. I don’t know the definition of the server-side class. It is best if you expose part of the code (or interface). There may be a problem with the server-side code.

Thank you for the reply from zcbb. The generated proxy class is definitely problematic. I generated the proxy class based on the parlay standard wsdl file. The source code of the proxy class and the project source code of the test program can be provided. The following is the source code of the getMywatchers method part of the proxy class (A bit messy, open it with ultraedit):

The method described in the parlayx standard is as follows:
8.3.4.1 Input message: getMyWatchersRequest
Part name presentity
Part type xsd:anyURI

8.3.4.2 Output message: getMyWatchersResponse
Part name Result
Part type xsd:anyURI [0..unbounded]

The wsdl of another interface of the standard deploys the webservice client in the same way, there is no problem,

Below is the information of this successful webservice

Regenerate the proxy class. The WSDL published by the server has changed
