Hi,

I am employing a webservice in my C# application. I have generated proxy
class for the web service thus I instantiate an object from that class
like it is local, use it and let it garbage collected.
That is all for my side but I don't have any idea about what happens on
the server side. There will be an HTTP connection between client and
server. Is this connection automatically closed by the infrastructure when
the webservice proxy object is finalized? What about the Session on the
server side, when is it closed? Is there anything I should do explicitly
with the webservice proxy object to close http connection and session on
server side?

You open the Web service connection from the client, and then it's the
client's responsibility to close the connection with a Dispose().

Web services are session less by default unless you have written code in
the Web service to keep session data.

But the Web Service proxy class inherits non-virtual Dispose method from
"Component" class which doesn't know anything about connection closure.
Right?

I don't use proxy. However, the proxy class is on the client side, and
it's doing the Dispose() of the connection. It's the same thing. If you
were not using a proxy, then you are still responsible for the close of
the connection with a Dispose() at some point in your code that would not
be using a proxy.

If you don't Dispose() the Web service is some fashion in code, then the
Web server itself is going to close the connection on a timeout to release
resources, so the Web server can process other requests of other Web
server clients, and you don't want that.

Hi Arnold,

Thanks for your help but I cant understand. I have a schema file for the
web service and I generated a proxy class by using wsdl.exe. My proxy
class doesn't have any method for connection closing. It just inherits a
Dispose method from "Component" class and I can't use the connection by
using this method. What should I do in this case? You said I am not using
proxy class, what do you for using web services?

I don't use a proxy class created by wsdl.exe. I don't know what control
you have over the Web service or your client project, but you can set a
Web Service reference to the Web service over HTTP to a remote Web service
localhost or remote Web service over the Internet.

.NET will take care of everything so you don't have to use wsdl.exe '
generated class, if you use a Web reference in the client project.

http://msdn.microsoft.com/en-us/library/xb5th1ba(VS.80).aspx

I would still do a ws.Dispose() to kill the connection that's being shown
to you in the examples.


It's also being talked about 'Web Service Reference' in a client project
on page 240.

I know using Web References and the book says generating proxy classes and
adding web references have same results. What I have will be a proxy class
over which I can call webmethods. But the problem is that the class doesn't
implement Dispose() method it just inherit it from the "Component" class
which is useless for connection closing. Does your class implement
Dispose() when you ass web reference? If yes can you send the
implementation?

Thanks.

Just use "using":

using (MyWebService ws = new MyWebService())
{
ws.DoSomething();
}

At this point the webservice instance has been disposed of.

The above is not a good practice, and as a matter of fact, when using a
WCF Web service, there is documentation that specifically indicates not to
use the Using statement on client connection to the WCF Web service.

http://www.devx.com/dotnet/Article/39023

WCF Webservice

var ws = new Webservice();

ws.DoSomething;

ws.Close();

legacy Webservice

var ws = new Webservice();

ws.DoSomething;

ws.Dispose();
