Consuming a Soa webservice with URL in the database

I am consuming a web service in my windows forms application by adding a web reference, for which I have the url stored in a database. Now that the endpoint url has been updated, I am wondering if I should update my reference within the solution or update the url in the database should be enough?
var addressService = new verify_client_ep();
addressService.url= objServiceURL.Table[0].WS_URL.ToString();
Please provide me with a solution.

I am consuming an external web service for which they have changed the url which I stored in my database. will updating the url to the new url suffice?
If they didn't change anything else but the endpoint, then yes.

How to get the WebService address dynamically from the txt file in Windows Forms

I'm building a small application and I'm using WebService in it. I was using a local WebService just by adding its reference in my project's solution manager.
My question is: is it possible to get the WebService url address dynamically, for example from a .txt file?
Thanks for every help.
Edit:
I want to change the WebService url address in my app's code. After that, the url will be placed in a .txt file and the app will get it from there.

You can set any url for your WebService client using the clients constructor. There you can provide the url to use:
var client = new YourServiceClient("<bindingName>", new EndpointAddress("<your url>"));

Please check solution here. They are accessing the URL from config file, instead of text while.

How to add a webservice url or a string in Configuration section

I created a vb.net Windows Form application and it consumes a webservice from url.
url = "http://localhost:1264/api/products"
request = DirectCast(WebRequest.Create(url), HttpWebRequest)
response = DirectCast(request.GetResponse(), HttpWebResponse)
I want to add the url string in Configuration Section(appConfig) and use this string in my code. How could i do this .
Please help

You should be add web service in window service application project
By right click on project, there is an option Add Web refereces like.
Then add your service what ever you want to use in this project.

Can you able to browse the url in any browser?
If you could able to browse, try adding the web reference with asmx extension

config web service from code behind

I am creating a windows mobile 6 application which will consume a web service (.asmx) for different clients.
As I know, I will need to manually “Add Web Reference”; then I will be able to call those functions.
Is it possible to configure web reference as a variable from code behind?
That way I can keep the url of web service in a text file. For different client, I just need to edit that text file instead of recompile that application again.

You'll have to add the Web Reference at design time.
At runtime, you can modify the URL of your target web service using the Url property. Here's an example of pulling the target URL from the app.config:
var ws = new MyWebService();
ws.Url = ConfigurationManager.AppSettings["SomeUrl"].ToString();
The only catch here is that the WSDLs of the design-time and run-time services must match.

Yes, just add something like :
<configuration>
<appSettings>
<add key="WebReference" value="URLofASMX"/>
...
then call it by :
string URL = ConfigurationManager.AppSettings["WebReference"].ToString();
You'll need to possibly add a new reference to System.Configuration to the project if you can't access ConfigurationManager just by including System.Configuration.

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");
