c# SOAP web service Complex type

I am new to SOAP complex type web services. I attached down here the wsdl file.
My question is
how to consume the web service? I mean how to call and how to call the callback function.
if possible, use the below wsdl and give me an example with c#
wsdl here
[wsdl here][1]

The easiest way I know to consume a SOAP API is to create a C# project and add a service reference.
Then add the address of your website and Visual Studio will generate a proxy for your WebService.
You will be able to call it in your project (Website/ConsoleApp).
You can have a sample of how to call the client when you call the svc of your WebSite if you use WCF.
ex: http://<host>[/route]/<name of svc>.svc

How to add web service (ASMX) refernece dynamically in C# (not to do "Add web Refernece" )

How to add webservice reference dynamically ?
I have created a class library project and i need to post data into a web service.
I don't want to consume web service as "Add Web reference" as i dont' want to use APP.CONFIG file and need to load this web service dynamically.
Please suggest me how dynamically i could load this web service inside this class library project ?
pLEASE share some code if possible.
Thank You

If you want to dynamically support different types of web services, they'll have to use an consistent interface so that a single set of classes can use the web services. Which will result in building a separate library.

Consuming webservice having WSDL and XSD files

We've requested a company to write a webservice that we can use to get some information.They have sent us WSDL and XSD files. Could you please tell me how I can use these files to query data?
I can do it easily if I have a link to a webservice. I just provide the link and Visual Studio generates web reference for me. After that I can use that reference just like a normal class. In this case I have no link. Just above mentioned files. Thank you.

You can create a proxy (add service reference in visual studio) from a wsdl file. You can read about svcutil at http://msdn.microsoft.com/en-us/library/aa347733.aspx, but VS2010 allow you to put a wsdl file on adress when adding service reference.

VS2010 can't create a web service reference from some WSDLs. Have
to write custom wrapper for those. OR edit your WSDL in a way so
VS can consume it. For example it may be ok for you to remove web
service method references for the methods that you are not planning to
use if those references create trouble for you.
Unless you're stuck with .NET 2.0, you should not use ASMX web service technology.
You should use "Add Service Reference" and point it to the WSDL on disk. It will create a set of "proxy" classes with methods that you can call just as though it were a "normal" class.
See "How to Consume a Web Service" for a walkthrough with example.
Use WSDL.EXE utility to generate a Web Service proxy from WSDL.
e.g.
wsdl /language:CS /n:"Microsoft.SqlServer.ReportingServices2010" http://<Server
Name>/reportserver/reportservice2010.asmx?wsdl

Web Service deployment in IIS?

I started learning web services. I learnt about web services, UDDI, WSDL, SOAP etc. and architecture of web services. Visual Studio is running the service in local system successfully.
Then I deployed the entire folder of that web service in IIS wwwroot, and tested. Its running successfully.
But when I remove the other file from the wwwroot\webService1 folder (I left only service1.asmx and bin folder) then also service is running.
Here I see that only two file are used in ruuning the webservice one is .asmx and another one is webService.dll in bin folder.
I'm not able to understand where is SOAP, WSDL, namespace or other things, that are required to run web service.
Please clarify.

SOAP, WSDL, Namespace are all handled by IIS and ASP.NET. In your scenario, your web service endpoint is your asmx file (no .cs file required in your deployment), and the DLL in the bin folder contains the code that you wrote for your webservice (so it does something).
If you call up your webservice in a web browser, you should see your web methods listed out to test. IIS knows how to process *.asmx files to do this. If you click on one, you should see a sample form (if input parameters are expected) and a button. Again, IIS knows how to serve this out to you. When you click the button, IIS and ASP.NET handle the work of SOAPing your request, handling it with your code, and SOAPing the response back to you.
If you create a "test" project in Visual Studio, and set a web service reference that points to your deployed web service, Visual Studio will create a proxy class and pull in some additional code from it's discovery of the service. Try it. You should get at least: a WSDL which defines your web service, a file called reference.cs which contains the code that does the heavy lifting of calling your webservice (SOAPing the request from your application and unSOAPing from the response).
If you download a tool called Fiddler, you should be able to intercept and inspect the SOAP call to your web service.
Take a look at Web Services with ASP.NET for additional information.

There are no such 'files' at all. The asmx and dll files contain all of the code for the service. You can see some of that in the URLs that are requested for the SOAP/WSDL info.

I believe if you append ?WSDL after .asmx you will see the definitions.
Such as this example:
WSDL Example

I think these are protocols and does not require anything. IIS and the requesting applications understand these protocols.

Can I generate proxy objects for WCF service library using scriptmanager?

I have used the AJAX Enabled WCF Service template from within a web application. By adding a Service reference to the scriptmanager, some client objects are generated allowing me to easily consume the service. My question is can I do anything like that when I use a WCF Service Library? I added the project to my solution and in my web app I added a service reference to the service. This is where I get a bit stuck. What do I do now to allow consuming the service from the client.

So, just to consume wcf service, you have to use "svcutil" app from VS pack to generate o proxy class, which is very simple in usage.
