C#中如何使用Web不可访问的WSDL/XSD实现SOAP服务？

Hey there! Let's break this down step by step to get you sorted with your SOAP service in Visual Studio.

1. First: Confirm if your service reference was generated correctly #

It's totally normal that you don't see a visible .cs file right away—Visual Studio hides the auto-generated code by default. Here's how to verify everything worked:

• In Solution Explorer, toggle the Show All Files button (top of the explorer pane).
• Expand your ePayments service reference, then expand the Reference.svcmap folder. You'll find the generated .cs file there (usually named Reference.cs).
• Alternatively, open the Object Browser (View → Object Browser), navigate to the ePayments namespace, and check for these key types:
  • rmt_wsClient: The main client class to call the service
  • remittanceXml: The request type
  • remittanceXmlResponse: The response type
  • UnsupportedEncodingException: The fault exception type

If all these exist, your service reference was generated correctly!

2. How to use the generated client to call the SOAP service #

Once you've confirmed the types are there, here's a concrete example of how to send a request matching the SOAP sample you provided:

using (var client = new ePayments.rmt_wsClient())
{
    // Build your input XML (match the structure from your SOAP sample)
    string inputXml = @"<remittance>
        <wsTin>Tin</wsTin>
        <wsUser>Username</wsUser>
        <wsPswd>Pswd</wsPswd>
        <contain>
            <bmrn>16GRIMXXXX00001746</bmrn>
            <blrn>TESTFOR1</blrn>
            <bcnt>1</bcnt>
            <bafm>099099099</bafm>
        </contain>
        <contain>
            <bmrn>16GRIMXXXX00001720</bmrn>
            <blrn>TESTFOR2</blrn>
            <bcnt>2</bcnt>
            <bafm>099099099</bafm>
        </contain>
    </remittance>";

    try
    {
        // Call the service method
        var response = client.remittanceXml(inputXml);
        
        // Access the returned XML from the response
        string resultXml = response.@return;
        Console.WriteLine("Service response: " + resultXml);
    }
    catch (ePayments.UnsupportedEncodingExceptionFault ex)
    {
        // Handle the specific fault from the service
        Console.WriteLine("Encoding error: " + ex.Message);
    }
    catch (Exception ex)
    {
        // Handle other general errors (e.g., network issues)
        Console.WriteLine("Error calling service: " + ex.Message);
    }
}

• Note: The using statement ensures the client is properly disposed after use.
• The @return property matches the <return> element in your XSD definition (the @ is needed because return is a reserved keyword in C#).

3. If you want direct control over the generated code (optional) #

If you prefer to have a visible .cs file in your project instead of the hidden service reference code, use the svcutil.exe tool (included with Visual Studio):

1. Save your WSDL content as rmt_ws.wsdl and XSD content as rmt_ws.xsd in the same folder.
2. Important: Edit the WSDL file to update the XSD reference from the remote URL to your local file. Change this line:

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

   To:

   <xsd:import namespace="http://remittance_ws/rmt_ws.wsdl" schemaLocation="rmt_ws.xsd"/>
   

3. Open the Visual Studio Developer Command Prompt, navigate to the folder with your files, and run this command:

   svcutil.exe rmt_ws.wsdl rmt_ws.xsd /out:RemittanceService.cs /namespace:MyApp.Remittance
   

4. Add the generated RemittanceService.cs file to your project, then use the rmt_wsClient class from the MyApp.Remittance namespace just like in the example above.

Quick checks to avoid issues #

• Double-check your app config file (App.config/Web.config) to ensure the service endpoint address matches the one in the WSDL: https://www1.gsis.gr/wsicispay/rmt_ws
• If you're testing in a non-production environment, make sure your network allows outbound calls to that URL.
