overloading default constructor in web services

[indigator]

I have an ASP.Net web service class, DataLayer.asmx.cs. I have two
constructors for the DataLayer class. One is the default parameter-less one
and the second one accepts a string argument. When I am trying to consume
this web service from another asp.net application, only the default
parameter-less constructor shows up. And if i try creating an instance of the
second constructor, it gives me a compiler error saying that No overload of
DataLayer() takes 1 argument. I checked the proxy class Reference.cs in my
client application and I couldn't find the overloaded constructor. Is it that
web services do not support overloaded constructors? Am i missing something?

Hello indigator,
What you see in the Reference.cs is a proxy and not the service itself.
The proxy itself has no knowledge of the implementation of the service. It
just knows any methods that are exposed by the service based on whats defined
on the wsdl. Possibly what you need in the constructor could be passed as
a parameter to the webservice.. or configured in the web.config that the
service can lookup

Hey Dilip,

Thanks for the reply. So does this mean Webservices do not support
Overloaded constructors? I am trying to pass some information as a parameter
to the constructor, so that the webservice can initialize the fields once the
instance is created. To be more precise, I am trying to create a datalayer
using webservices. So i need to pass the connection string as a parameter to
the webservice class. Currently, when i try to create an instance of the
webservice class from an asp.net application, it shows only the default
parameter-less constructor, even though I have specified 2 constructors. If I
ignore this and try to create an instance using the 2nd constructor(with
parameter), it gives me a compilation error saying that "No overload for
method 'MethodName' takes '1' arguments.

I cannot specify this in the web.config file, since everytime, they need to
connect to a new database, the web.config has to be changed. So does this
mean I should have another Web method which will perform the same function
and not use the constructor? I hope I am clear.

Thanks.

Hello indigator,
Why not just pass in an (encrypted ??) connection string as a parameter
to the web method?

Hey Dilip,

I guess I will do that. I just preferred passing it as a parameter to the
constructor since I didn't want client applications to call one extra method
to set the connection string. :)

Thanks for your help.
