How to consume a wsdl file that doesn't exist on web in C#

Question

I am trying to impliment a service with SOAP messages to my visual studio project. They gave me some instructions and I saw on stackoverflow that I have to consume the wsdl and xsd file in visual studio so that it can create all the classes that I need. The problem is that when I try to add the wsdl file as service reference it says that the file doesnt exist. I search it myself using the URL provided and it really doesnt exists. Is there any way so that I can use it.

Below is the WSDL statement:
https://www1.gsis.gr/wsicispay/rmt_ws?wsdl
<definitions targetNamespace="http://remittance_ws/rmt_ws.wsdl" name="rmt_ws"
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://remittance_ws/rmt_ws.wsdl"

<types>
<xsd:schema>
<xsd:import namespace="http://remittance_ws/rmt_ws.wsdl"
schemaLocation="https://www1.gsis.gr/wsicispay/rmt_ws?xsd=1"/>
</xsd:schema>
</types>
<message name="remittanceXml">

<port name="rmt_ws" binding="tns:rmt_wsBinding">
<soap:address location="https://www1.gsis.gr/wsicispay/rmt_ws"/>
</port>
</service>
</definitions>

and here is the xsd

Those are in a pdf file that they gave me.

EDIT: If I add it as a file from service references it creates the reference ePayments and no .cs file. When I add the reference it gives me only one service rmt_ws which has an operation remitanceXML and nothing else. I don't know if this is correct and how should I use it

Answer 1

I copied the xsd part into the wsdl and visual studio generates a service with one operation to send an input XML and return another XML. I hope, this helps.

rmt_ws.wsdl:

Answer 2

I remember, that I had a problem with authentication of a web service some years ago, but I didn't remember where I found this alternative solution:

• Create a new console app in visual studio (I am not sure, if deleting the old service reference in the existing project works without manual editing project file etc.)
• Select add service reference as before, but don't enter the path of a wsdl. Instead press the button "Advanced..." in the dialog and "Add Web reference..." in the next dialog.
• In the new dialog enter the path of the wsdl file and press "Add reference"

• Open the file "program.cs" in the project and add this class with namespace between the last "using..." line and "namespace...."

   namespace TestWeb.WebReference { partial class rmt_ws : System.Web.Services.Protocols.SoapHttpClientProtocol { protected override System.Net.WebRequest GetWebRequest(Uri uri) { System.Net.HttpWebRequest request; request = (System.Net.HttpWebRequest)base.GetWebRequest(uri); if (PreAuthenticate) { System.Net.NetworkCredential networkCredentials = Credentials.GetCredential(uri, "Basic"); if (networkCredentials != null) { System.Diagnostics.Debug.WriteLine("User: " + networkCredentials.UserName); System.Diagnostics.Debug.WriteLine("PW: " + networkCredentials.Password); byte[] credentialBuffer = new UTF8Encoding().GetBytes(networkCredentials.UserName + ":" + networkCredentials.Password); request.Headers["Authorization"] = "Basic " + Convert.ToBase64String(credentialBuffer); } else { throw new ApplicationException("No network credentials"); } } return request; } } 

• Replace "TestWeb" (first line of inserted code) with the namespace of your project (normally the project name).

• Replace the existing class "Program" with the following code:

   class Program { static void Main(string[] args) { // Fill with a valid xml request String inputXML = ""; String answer = ""; try { WebReference.rmt_ws _webService = new WebReference.rmt_ws(); System.Net.CredentialCache myCredentials = new System.Net.CredentialCache(); // Set correct user and password System.Net.NetworkCredential netCred = new System.Net.NetworkCredential("User", "Password"); _webService.Credentials = netCred.GetCredential(new Uri(_webService.Url), "Basic"); _webService.PreAuthenticate = true; answer = _webService.remittanceXml(inputXML); } catch (Exception ex) { Console.WriteLine(ex.Message); } Console.WriteLine(answer); Console.ReadLine(); } } 

• Set inputXML with a valid xml for your request

• Set the correct user and password

If this does not help you should really open a new question to find some one other who could help.

Answer 3

I contact again for the communication problem and they send me this xml

Can I use this file in visual studio ? Is this better for the previous?
