c# Soap Client Issue - more than one endpoint configuration for th at contract was found

Question

I am trying to write a simple c# console application to test the SOAP API from here: https://www.imailtest.co.uk/webservice/imail_api.asmx?wsdl (or https://www.imailtest.co.uk/webservice/imail_api.asmx to see the api methods)

So, I added this reference and tried to invoke 2 api methods (Authentiacate & ProcessPrintReadyPDF) calls on it and got this error:

Error : An endpoint configuration section for contract 'ServiceReference1.imail_ apiSoap' could not be loaded because more than one endpoint configuration for th at contract was found. Please indicate the preferred endpoint configuration sect ion by name.

Here's my C# Code:

static void Main(string[] args) {     // Anticipate Error     try     {         // Generate SOAP Client         ServiceReference1.imail_apiSoapClient soapClient = new ServiceReference1.imail_apiSoapClient();          // Login         Console.WriteLine("Authenticating");         soapClient.Authenticate(iMailUser, iMailPass);          // Proceed If PDF File Exists         if (File.Exists(PDFFile))         {             // Upload PDF File To iMail             Console.WriteLine("Uploading PDF File");             soapClient.ProcessPrintReadyPDF(File.ReadAllBytes(PDFFile), "", true);              // Test Complete             Console.WriteLine("Done");         }         else         {             // Log Error             Console.WriteLine("PDF File [{0}] Does Not Exists", PDFFile);         }     }     catch (Exception ex)     {         // Log Error         Console.WriteLine("Error : "+ ex.Message);     }      // End Test     Console.WriteLine("Press any key to continue ...");     Console.ReadKey(); } 

This is how I added the service reference to my console app:

Any ideas?

Answer 1

In your App.config you can see some thing like this

 <client>       <endpoint address="https://www.imailtest.co.uk/webservice/imail_api.asmx "         binding="basicHttpBinding" bindingConfiguration="xxxxxxxxxx"         contract="xxxxxxxxxx" name="xxxxxxxxxxxxx" />       <endpoint address="https://www.imailtest.co.uk/webservice/imail_api.asmx"         binding="customBinding" bindingConfiguration="xxxxxxxxxxxxx"         contract="xxxxxxxxxxx" name="xxxxxxxxxxxxx" />   </client> 

remove the second endpoint and now it should be like this

<client>       <endpoint address="https://www.imailtest.co.uk/webservice/imail_api.asmx "         binding="basicHttpBinding" bindingConfiguration="xxxxxxxxxxxxx"         contract="xxxxxxxxxxxxxx" name="xxxxxxxxxxxxxxx" />         </client> 

now run the code , hope your code works fine

Answer 2

I believe the problem is solved via defining the contract name like so (based on my screenshot):

ServiceReference1.imail_apiSoapClient soapClient =  new ServiceReference1.imail_apiSoapClient("imail_apiSoap"); 

Now, I am no longer getting an error and the api appears to be working.
