Question

i want to use the below Web-Service :

https://acquirer.sb24.com/ref-payment/ws/ReferencePayment?WSDL

and builded config file after adding ->

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="PaymentIFBinding" closeTimeout="00:01:00" openTimeout="00:01:00"
                    receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false"
                    bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
                    maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
                    messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
                    useDefaultWebProxy="true">
                    <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
                        maxBytesPerRead="4096" maxNameTableCharCount="16384" />
                    <security mode="Transport">
                        <transport clientCredentialType="None" proxyCredentialType="None"
                            realm="" />
                        <message clientCredentialType="UserName" algorithmSuite="Default" />
                    </security>
                </binding>
                <binding name="PaymentIFBinding1" closeTimeout="00:01:00" openTimeout="00:01:00"
                    receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false"
                    bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
                    maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
                    messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
                    useDefaultWebProxy="true">
                    <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
                        maxBytesPerRead="4096" maxNameTableCharCount="16384" />
                    <security mode="None">
                        <transport clientCredentialType="None" proxyCredentialType="None"
                            realm="" />
                        <message clientCredentialType="UserName" algorithmSuite="Default" />
                    </security>
                </binding>
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="https://acquirer.sb24.com:443/ref-payment/ws/ReferencePayment"
                binding="basicHttpBinding" bindingConfiguration="PaymentIFBinding"
                contract="SB24Service.PaymentIF" name="PaymentIFPort" />
        </client>
    </system.serviceModel>
</configuration>  

i want to call verifyTransaction method of this WebService :

PaymentIFClient pic = new PaymentIFClient();  

double pic_result = pic.verifyTransaction(str1, str2);  

but the first line throws the below error :

Could not find default endpoint element that references contract
‘SB24Service.PaymentIF’ in the ServiceModel client configuration
section. This might be because no configuration file was found for
your application, or because no endpoint element matching this
contract could be found in the client element.

EDIT :

“This error can arise if you are calling the service in a class
library and calling the class library from another project.” -> My
Situation is like this …

what should i change i configuration file ?
thanks in advance

Editing wcf configuration by hand is tricky, as there are many sections that need to be correct and correctly reference each other. Try opening your app.config file in SvcConfigEditor (also available from the Tools menu in Viusal Studio). It is way easier to get things correct when having GUI help on what to do.
