Deserialization failed

Question

Hi to all
i have create a simpl .NET application in C# that call a web services in SAP. The call are in the next code:
MDM_SAP.Bapiret2[] myRet = new NBMI.MDM_SAP.Bapiret2[2];
myWS.Zmdm00AllCreUpd(CAP, CDC, CodDecreto, Divisione, Email, Fax, Frazione, IdSede, Indirizzo,
                    Lingua, Localita, MacroArea, Nome, Note, NumCivico, Nazione, Provincia, Regione,
                    ChiaveRic1, ChiaveRic2, StatoSede, ref myRet, NumTel, TipoPV, TipoSede);
When i try to test this WS raise an  exception with the next message: "Deserialization failed " .
Why? Where is my mistake?
Thank in advance

Hi Enrico,
The deserialization error can be due to the following:
1. The web service WSDL or operation's signature has changed from what it was consumed in your client. You'll need to check this with the WSDL comparison and carry out the required steps.
2. There is underscore in the member variable names of the complex types used as the web service parameters. This problem is not clearly defined anywhere, but if you try to search in the [Web Dynpro for Java forum|Web Dynpro Java; you'll be able to find many threadsregarding the Deserialization error and solving it by removal of underscore.
