I need to consume a service endpoint which is WSDL.
I tried adding it as a webreference and service reference. In both occasions I couldn't find an effective method to fetch data.
Below is the service consumed in SoapUI -
When you added ServiceReference, it would have created a Client\Proxy Class as well. This client in actual serializes the data into soap format, sends it over the network and then deserializes the soap response into memory response objects which you can consume
when you do a "Add Service Reference", on the dialog that comes up, click on the [Advanced] button in the button left corner and on the next dialog that comes up, pick the [Add Web Reference] button at the bottom.
Notice that there is a namespace, have you included that namespace in the class that is calling the web service
That namespace should contain a client class that will allow you to invoke the web service
I could consume this service by creating the client object and calling the method from client.

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.
one of my friend made a soap webservice in PHP and now i have to consume it into my winform app. I added web Service Reference , pasted the URL and it is showing method name.
The method name is Display().
Now after adding when write code on button click, it is showing following three methods:
MyWebServiceName. DisplayCompletedEventArgs
DisplayCompletedEventHandler
SiteControllerService
There is no soapClient or direct Display method ,any one know , what am I doing wrong?
Check the WSDLyou must have in the VS project. You will find the service name:
Ex:
<wsdl:service name="SiteControllerService">
So you must type:
MyWebServiceName.SiteControllerService SOAPclient = new MyWebServiceName.SiteControllerService();
SOAPClient.Display();
Visual Strudio create a namespace to encapsulate all classes generated to work with the web service. In that namespace you will find the soap proxy client, events and events handler and any data transfer object needed to pass parameters to proxy client or to recive the response.
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've been tasked with creating a class wrapper for a SOAP service, the idea is that you'll be able to treat it as a regular class. The main reason for this is that the WDSL for the SOAP service contains only one method and it's got 5 parameters and it's only kind of OO so you'd have to know all the method calls really well and it's a bit hard to remember them all.
OK, so I've tried adding a web reference, now web references can now be added as service references in VS 2010. You click add service reference advanced etc and it puts in a service reference. Great. Unfortunately if I try and access this from a class I can't.
I can build a console app and put code in the main procedure and access the method of the SOAP service fine but when I add a reference to a class library the intellisense won't allow me to select anything. I'd instantiate an instance like so:
SOAPService.webServiceService ws = new SOAPService.webserviceService();
ws.
and then the intellisense refuses to kick in. If I do the same in a web project or a console app then I can access it fine. I've added the namespace I've done all kinds of things. Also, I can add a web reference and get a DISCO file whenever I create a web project.
OK, also while I'm on the subject I also need to pass credentials to the web service in PHP.
The problem is that in the past I'd create some .net system credentials and add these and it would usually pass through if I was connecting to another .net service.
How should I be sending them to a PHP web service? I always get either invalid username/password combo errors or envelope malformatted error types
Thanks

So the intellisense is not working, but if you add the method in and try to use it does it work, or produce an error?
With regard to diagnosing authentication issues try using fiddler to view the SOAP messages that are being sent, and to view the reply. Do you have some other software that connects and authenticates to that service? Use fiddler to look at the SOAP messages and compare them to see if the header is different etc.
I'd normally do it like this,
using (Service service = new Service())
{
service.ClientCredentials.Windows.ClientCredential.Domain = "domain";
service.ClientCredentials.Windows.ClientCredential.Password = "password";
service.ClientCredentials.Windows.ClientCredential.UserName = "username";
}
Also with regard to the service working or not in general use fiddler if you have any problems, you can see the SOAP messages and it often gives you a clearer message.
I know in IIS you can turn on failed request handling that also gives you an insight from what is going on at the server end, perhaps you have some form of logging too for your php service?
Are web service calls synchronous or asynchronous by default? How is synchronicity determined, by the service or by the client?
I have code similar to the following:
try
{
string result = MakeWebServiceCall_1(); // this is a third party webservice
MakeWebServiceCall_2(result); // another webservice which must happen *after* the first one is complete
}
catch()
{
SetStatus(Status.Error); // this calls my own stored procedure
throw;
}
SetStatus(Status.Sucess);
In the above, SetStatus is writing to the same tables that the third party web services read from. If I change the status before both web service calls have completed, it's going to make a big mess and I'm going to get fired. How do I know/ensure that the webservice calls are synchronous?
According to MSDN when you add a reference to a Web Service it will implement methods to call the Web Service both synchronously and asynchronously in the proxy class. You just need to make sure you call the right one.
After you have located an XML Web service for your application to access by using the Add Web Reference dialog box, clicking the Add Reference button will instruct Visual Studio to download the service description to the local machine and then generate a proxy class for the chosen XML Web service. The proxy class will contain methods for calling each exposed XML Web service method both synchronously and asynchronously. Source
