I have created a SOAP service.
Now i want to consume it in a c# client application. I added the service using 'Add service reference' and service reference is added to client.
All my service entities are in service. And in current scenerio i can't move them to a common library.
Problem is, my service endpoint is accepting List<Foo> as parameter.
Foo has a method Boo.
In client, when i try to Foo.Boo() i get Cannot resolve symbol Boo error.
Unfortunately only methods on the service itself are exposed via a SOAP web service, methods on objects used as parameters or return values are not. If the method relates to a server-side operation then you could expose it at the service root level taking the instance object as parameter, or if it relates to a client-side operation you could consider adding it as a client-side extension method.

i have one doubt in Web Service / WCF
i'm creating the service and it's having 10 methods respectively
test1() , Program1(int age),Describe1(), DisplayAge(string name),,SimilarInterest(),ServiceCall(), Hide(), Difference(), WebService() and Help()
now after hosting this service in asmx only the below methods should display. others should not need to display.
DisplayAge(string name),,SimilarInterest(),ServiceCall() only these three should display when i call the http://URL.asmx?wsdl
the other 7 methods should not need to display in asmx wsdl file .how to do that?
As far as I know, in XML Web Service(ASMX), this should not work if you want the service to be both invoked and not shown in the WSDL. Either using private decorated methods or removing the [WebMethod] attribute causes the method to no longer be invoked. If in WCF we can implement authentication, authorization that individual methods cannot be invoked, or simply not expose metadata. But we cannot hide the specified method (but can be called by the outside world).

Feel free to let me know if there is anything I can help with.
I'm using an external open source project that provides me computation services that I create using a UI that it provides.
The project creates web-service endpoints automatically that I'm suppose to consume via my application.
My problem is that I can't interfere in the process. It's a black box that creates a service for me when I choose to deploy the project.
Each service has a bunch of different logical "private methods" that are exposed in the wsdl that's automatically created.
If I could create the service myself, I would create one an interface with an exposed method called Process that will have one general input request param and one general Response, something like:
public GeneralResponse Process(GeneralRequest request);
I want to create a generic out-point in my application which passes two parameters:
1.Endpoint Url to shoot the request to.
2.Generic request as an input param.
I'm using C# and the easiest way to consume a service is simply adding a service-reference, creating a client and calling the wanted method.
Since I don't want to add a client per service reference, I'll add a random one, change the client's endpoint address and shoot the request.
The problem with this approach is that the client generated will expose it's "private methods" and I don't want other programmers on my team to accidentally invoke them.
Bottom line:
Is there any elegant way to create a Generic soap client and invoke a method using a string? Similar to the way you call the Invoke method when you use reflection?
Something like this:
GenericRequest req = GetRequest();
SoapClient client = new SoapClient(endpointUrl);
GenericResponse res = client.Invoke("Process", req) as GenericResponse;
Hi I have a WCF service and within it I have this method
void SendData(int pumpNo, List<String> pumpInfo);
however when I try to pass an int and a list into it, I get an error saying
Error 1 No overload for method 'SendData' takes 2 arguments
This is how I passed data to it in the WCF client
sendpumpdata.SendData(pumpID, pumpData);
ok so at the top I create an instance of the WCF service by doing...
ServiceReference1.iCommClient sendpumpdata = new Pumps.ServiceReference1.iCommClient();
also in my service.cs I have created the method defined in the IService.cs
A WCF web service leverages client generated code (i.e. a proxy) to communicate with the server. In your situation, even though the server code has two parameters, your client generated code must be out of date.
If you're using a Web Reference or a Service Reference just right click and Update Reference. If you're using a static WSDL then navigate to the WSDL hosted locally for the WCF service and save it to disk and then overwrite the one in your project.
I have a webservice on a remote host that I need to invoke from ASP.NET/C# class. What is the simplest way of calling a method via SOAP, given WSDL url and a method signature?
Given:
WSDL url as string(available only at runtime, i.e. variable)
Method signature(constant)
Need to:
Create a soap client and perform method call.
The simplest thing to do is to just use "Add Service Reference" and point to the WSDL. It will generate the proxy classes for you, including a proxy method which should match the method signature you've been given.

Its very easy in visual studio - you simply add the web reference url and it generates the proxy stub for you.
I'll be more specific.
Lets say I have a contract defined for my WCF service. And I have two different WCF clients which reference to this service : "ClientA" and "ClientB".
Now , lets say I want to add an operation (method) to my service which only "ClientB" will use , Lets say I added this operation to the contract and "ClientB" updated its reference and we're all happy. Does clientA also need to update it's reference even though it is not using the new operation?
The client only needs to update his reference, if it's going to use the new Operation contract.

No, WCF web references are generated by the IDE very similarly to references to ASMX or other web services, which means that it breaks things down into a method inventory, such that the client calling code operates as though it were invoking a remote API. Therefore, if only new stuff that does not alter the expected existing functionality is added, then old clients do not need to update.
