C# SOAP with a custom URL - c#

Okay, simple situation: I'm writing a simple console application which connects to a SOAP web service. I've imported a SOAP Service reference and as a result, my application has a default endpoint build into it's app.config file.
The web service, however, can run on multiple servers and the URL to the proper web service is passed through the commandline parameters of my application. I can read the URL, but how do I connect the web service to this custom URL?
(It should be very simple, in my opinion. It's something I'm overlooking.)

Is this using an auto-generated class deriving from SoapHttpClientProtocol? If so, just set the Url property when you create an instance of the class.

Well, .NET can provide some very useless error messages sometimes. In IIS, the service was configured to AutoDetect cookieless mode. As a result, I had to append "?AspxAutoDetectCookieSupport=1" to the URL. Although that would fix the problem, it was just easier to go to the IIS console, open the properties of the service, go to the ASP.NET tab page, click the "Edit configuration" button, to to "State Management" in the newly popped up screen and change "Cookieless mode" into something other than "AutoDetect"...
Excuse me. Dumb error. Am going to hit myself on the head a few times for this. ;-)

As Jon said, you set the Url, as in:
Namespace.ClassName nwe = new Namespace.ClassName();
nwe.Url = "http://localhost/MyURL/site.asmx";

calling the service URL

I am trying to call a credit card WSDL soap service in my ASP.net web forms. I tried to add the reference of the service in my application. I got the error "Page cannot be displayed. I asked the vendor and he told me that I am using older version of .net and I should use below line of code to fix the issue
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12
Where should I put the above line in my code and by putting the above, will I be able to call the service. Below is the screenshot of the error message when I am trying to call the service.
There are 2 ways to add a web reference on a project in visual studio.
Using an Url. In this case you can try typing the url on any browser and adding ?wsld at the end of the url, it should to show you the contract just there (like and xml). If it works then you can use THAT url (including the ?wsdl part) as the reference.
From a local file. In this case you can download the wsdl file from the browser (changing the extension to .wsdl when you download it) using the same way as I explained before but when the browser shows you the xml then you download it with the right click. Then in the web reference URL you can reference to the local path of the file.

How to create a SOAP Request C#

I know there are thousands of step-by-step samples for consuming a SOAP project with C#.
Actually, I tried many of those but didn't really get to understand how it works, how were needed components built or how to integrate a certificate for a secure connection.
I would be really grateful if any of you guys have a magical resource, since I read somewhere I shouldn't do it this way or another, I really want to know this well.
Thank you,
Best regards.
It's really simple actually. Suppose you have a service at http://myhost.com/XService.svc - right click References in the solution explorer and choose "Add a service reference" (older versions of VS called it web reference/web service)
A wizard appears; pop your URL into it, set a few options and hit Go
You'll get a client class set created that references the service, with methods that take a set of typed parameters based on what the service said it wanted when VS queried its WSDL. You might use it like:
var c = new XServiceClient();
bool result = c.CreateNewPerson("John Smith", 30, "js#hotmail.com");
The service client handles all of the xml creation, tcp socket connection, data transmission etc necessary to pass those 3 values you sent, to the web service so that the relevant method is called, the response is returned etc

Creating SOAP message body

I would like to know how to create SOAP message, body, and envelope in C#. Any help or links appreciated.
I need to send a SOAP attachment to a third party Web Service. I don't need WCF. I know how it works. My client needs SOAP with attachment.
Here's a really super-short intro how to do this:
1) Create a new project (any kind - console app, windows app, web app - whatever) - File > New > Project
2) In your Solution Explorer, right-click on References and choose Add Service Reference
3) In the dialog box that pops up, you need to enter two things:
your URL where the service lives (typically with a ?wsdl query string to grab the WSDL - the service description)
your namespace where the service classes will live - pick whatever suits you
Then click on Go - this will talk to that service and see what it has to offer
4) Now, that dialog box should update, and show you the service and its operations, as discovered by Visual Studio:
5) Click on OK and some code gets generated in the background
6) Now instantiate a client-side proxy in your code, and call a method on it:
That's all you have to do - everything else, all the messy details of creating a SOAP header and message body, can be happily left to the WCF runtime.
Now go learn WCF!
marc_s: learn SOAP with Attachments before recommending others to learn WCF. SwA is not supported by .Net so he's got to roll his own and that is the background for his question.
Check this link out http://www.xefteri.com/articles/show.cfm?id=15
It describes process for VS.NET, but in VS2010 it is same process. This was an easiest way.
However, if you can construct SOAP message (for example, if you read WSDL and can construct message without any issues or you used something like SOAP UI (http://www.soapui.org/) to generate few mock up messages and got an idea) then you can simply do POST to that URL like in this example http://www.808.dk/?code-csharp-httpwebrequest

Custom SharePoint 2010 WCF Service - How to set MaxReceivedMessageSize parameter

I have developped a custom WCF Web Service within a SharePoint 2010 Visual Studio empty project.
My web service is working well. The problem is related to the size of the request I can send to this web service. I have realized that is something around 300Kb. If I go bigger than that, the service/client is sending me an exception.
I've looked around on the web and see that the MaxReceivedMessageSize setting may be my solution. I've tried using a FeatureActivated method to set this information using this kind of request:
// increase maximum size of requests to this web service: http://msdn.microsoft.com/en-us/library/ff599489.aspx
SPWebService contentService = SPWebService.ContentService;
contentService.ClientRequestServiceSettings.MaxReceivedMessageSize = -1;
SPWcfServiceSettings csomWcfSettings = new SPWcfServiceSettings();
csomWcfSettings.MaxReceivedMessageSize = 10485760; // 10MB
contentService.WcfServiceSettings["PT-SP-P2S-DocumentCreator.svc"] = csomWcfSettings;
contentService.Update(); // access denied thrown here!
With that code, I have an Access denied (I'm actually the Site Collection Administrator).
I also know that this parameter may be set in the app.config of web service host but, in SharePoint, where to I need to change this parameter.
I think you should make this change in the web.config file of the Web Application in which the feature is activated. SharePoint provides APIs to make web.config changes. In fact, using APIs to make changes to your web.config is preferred option because SharePoint uses Timer Job and makes same updates to all Web Front End servers in your environment. There are 2 ways to make changes to web.config as described here:
http://msdn.microsoft.com/en-us/library/ms460914.aspx
In your case, since you want to make the change only when your feature is activated, you would take the API approach as documented here: http://msdn.microsoft.com/en-us/library/bb861909.aspx

Connect to Unknown SOAP Web Service

I would like to build an app in C# that connects to an Apache AXIS web service and performs the following operations via SOAP.
Login in to the server.
POST string data to server
Receive and display server response
Here's the tough part. I do not have access to the server, nor do I know where the .JWS file is located on the server. I was able to get to the WSDL file in my web browser, so I know a "Login" operation exists as well as an operation to take in data.
I have tried accessing the web service via URL, but I keep getting this message:
Hi there, this is an AXIS service!
Perhaps there will be a form for
invoking the service here...
In summary, is there anyway I can connect to this web service when all I have is the URL of the WSDL file? Are web services accessible via URL?
Thank you
Use WCF, and generate client proxies to the web service using the svcutil.exe tool.
running svcutil.exe http://url.to/webservice?WSDL the_wsdl.wsdl /language:C# should generate proxy classes you can use in your C# project, and you'd call the service e.g. like
BasicHttpBinding myBinding = new BasicHttpBinding(); //might not even need these
// 2 lines if you ran svcutil.exe directly on the web service URL
EndpointAddress myEndpoint = new EndpointAddress("http://url.to/webservice");
TestClient client = new TestClient(myBinding,myEndpoint); //the generated classes
// svcutil.exe created
client.SomeOperation(42); // call an SomeOperation of the web service
Thanks for everyone's help. Looking back on this question, I can see how severely confused I was. Here is the solution I followed.
Assuming you know the URL of the WSDL file of the service you wish to connect to then just do the following.
Boot up Visual Studio
On the top toolbar navigate to Data -> Add New Data Source then choose Service in the new dialog
In the address bar, enter the URL of the wsdl file (EXAMPLE: http://server.com/services/displayName?wsdl)
Near the bottom of the dialog, change the namespace to something relevant to the project (EXAMPLE: sampleService)
Now Visual Studio should compile the client proxies for you that you can use to access the web services on your server. To access one of the services, all you need to do is create a new object from the class.
//Example
sampleService.ClassName test = new sampleService.ClassName();
test.displayName("Jack");
