How to alias 2 classes in c#

[Marc Gravell]

Well, if you use wsdl.exe at the command-line, you can use /sharetypes
to do this, specifying multiple urls (or other sources) to inspect.

That do?

Hello,

Here is my pb: I have a group of classes in 2 namespaces which are exactly
simlilar.
Theses classes are generated by Visual Studio when inserting a Web
Reference, having 2 versions of a web service with a total compatibility in
data structures, I need to write a program able to deal indiferently with
any version of the web service.
Writing a compatibility layer is very long and need lot of unecesary
create/delete to transfert from one object to its correspondant object and
call the web service api without having compiler refusing.

It could be very usefull to have something abale to say 'class1 is an alias'
of class2 and to be able to cast directly object of class1 to class2 and
vis-versa. All methods and properties of the class having same names and
type.

Any idea ?

Thanks, CS.

Hi CS,

For ASP.NET webservice's client proxy, if you use "Add WebReference" to
create the proxy, it will always create a new copy of the custom types(even
if you have add multiple reference to services that use the same custom
types).

As Marc suggested, you can use wsdl.exe commandline utility to generate
the proxy, this tool has "SharedType" option that will indicate the proxy
generation to share types.

#Proxy Type Sharing

So far for webservice, the type sharing support is still limited. In WCF ,
type sharing between multiple clients or even existing class library
asemblies are much more enhanced.

Thanks to Marc and you Steven, I will do a try.
Something like
using class2 = class1 would have also been usefull.
