Calling a method on a webservice

[bjornms]

Hi,

I have a question related to webservices on the Microsoft platform.

Context:
I have two projects. One is called LogService. The other is called
client. The LogService is a C# webservice developed on VS.NET 2005.
The client is a seperate project developed in VS.NET 2005 which uses
(in the project using a webreference) the webservice LogService.
Introduction:
I'm trying to call the method Log with an argument Window on a
webservice called LogService. This Window Class is defined under the
namespace House in the webservice project. So if i want to instantiate
a Window in the LogService, i do the following: "House.Wind ow window =
new House.Window(); ".

If i want to call the Log method on the client project which has a web
reference to the LogService named LogService i do the following:
LogService.LogS ervice logService = new LogService.LogS ervice();
LogService.wind ow window = new LogService.Wind ow();
logService.Log( window);

But...:
My situation is different.
For some reason ( i'm not going to explain it here ), i do not use the
Window definition from LogService. Instead, on the client project i
also have a namespace House with a class Window, which is exactly
identical to that on the webservice LogService. To call the method Log
i do the following:
LogService.LogS ervice logService = new LogService.LogS ervice();
House.Window window = new House.Window();
logService.Log( window);

But... then i get some errors which i can not get rid of.
The errors i get:
1) The best overloaded method match for
'LogService.Log Service.Log(Log Service.Window) ' has some invalid
arguments
2) Argument '1': cannot convert from House.Window to LogService.Wind ow

And i also can't cast between the two classes.

My Question: Does somebody know how to fix those errors? Has it
something to do with Namespaces? I'm lost here.

The two classes are not related in any way that matters to C#. Of course
you're going to get errors. You'd get the same result if you passed an
"int".

Ok, they are not related for C#. For me they are. Actually, for me
they are identical. So is there a way to typecast between the both? Or
do i have to create a copy constructor? Or is there another solution
to this problem?

As john pointed out the classes are not the same. If your using WCF it is
fairly easy to modify the generated proxy code and replace class
implementations . If you are using pre .net3.0 web services you may be able
to do something similar.

You need to modify the generated client proxy class and replace the
generated LogService.Wind ow class with House.Window. You need to make sure
that your implementation of House.Window is decorated with the same
attributes as the class in the generated client proxy. After applying the
same attributes you then need to modify the generated client proxy class to
use House.Window instead of LogService.Wind ow.

To my mind, it would be safer not to edit the proxy class, as it is a
generated class. Instead, yes, create a copy constructor.
