Develop Reference

How to get data from Business Central?

I have made a C#-project where I am trying to connect to my Business Central cloud sandbox.
In Business Central, I have made an extension with a new codeunit, which has a function that I call "MHSTest". It just returns a text.
In Visual Studio, I have made the service reference that connects to the SOAP URL in Business Central. So I can see the name of my function, "MHSTest", in Visual Studio.
When I write this in Visual Studio, I get an error, because it tries to connect anonymously:
var client = new MHSTest.CSharpCodeunit_PortClient();
myTextBox.Text = client.MHSTest();
If I try the below instead, I get an error message saying that "https" is not valid. It has to be "http".
string endpoint = "">api.businesscentral.dynamics.com/.../CSharpCodeunit";
var binding = new BasicHttpBinding();
binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Windows;
binding.MaxBufferSize = 999999;
binding.MaxReceivedMessageSize = 999999;
var client = new MHSTest.CSharpCodeunit_PortClient(binding, new EndpointAddress(endpoint));
myTextBox.Text = client.MHSTest();
How do I connect to Business Central and get (or set) data?
App.config:
<?xml version="1.0" encoding="utf-8" ?>

contract="MHSTest.CSharpCodeunit_Port" name="CSharpCodeunit_Port" />
</client>

The problem is solved. I just needed to add this code after defining my client variable:
System.ServiceModel.Security.UserNamePasswordClientCredential cre = client.ClientCredentials.UserName;
cre.UserName = " ";
cre.Password = " ";

Use the Export-NAVData cmdlet to export data from a Business Central database. You can export company-specific data, and you can choose to include global data, application data, and application objects. When you export data from a Business Central database, the data is stored in a file with the extension .

Programmatically define the Endpoint and Binding

Warping the call of a web service in a Class Library, I had to past the endpoint definition from app.config to other project that was using the Library.
In order to get rid of that I try to translate my app.config setting into explicit in order to pass Binding and Endpoint definition to the ClientBase.
var client = new myServiceClient(customBinding, custonEndpoint);
I'm looking for a way to translate system.serviceModel definition into code.
And the simpliest definition is giving me issue. For example with the following configuration:
<system.serviceModel>
<bindings>
<netTcpBinding>
<binding name="NetTcpBinding_MyService" />
</netTcpBinding>
</bindings>
<client>
<endpoint address="net.tcp://address:port/Foo/Services/MyService"
binding="netTcpBinding" bindingConfiguration="NetTcpBinding_MyService"
contract="MyService.MyService" name="NetTcpBinding_MyService">
<identity>
<userPrincipalName value="FooBar#SecondLevel.TopLevel" />
</identity>
</endpoint>
</client>
</system.serviceModel>
I find no property that match those parameter in NetTcpBinding neither in the Security property:
var endPoint = new EndpointAddress(__EndPoint);
var binding = new NetTcpBinding();
binding.Name = "";
Resulting in an error SSPI.

BasicHttpBinding from app.config inaccessible in code

I have several web services that I am connecting to from a Visual Studio C# project using service references. Two of the service references were created and work without a problem, and one of them took quite a lot of effort to get imported, and now seems to not be working.
I believe the problem lies in the app.config file since it is getting a "Could not find endpoint element" error when I try to create the client.
Here is the app.config
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
</configSections>
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="RateQuoteSoap">
<security mode="Transport" />
</binding>
<binding name="RateQuoteSoap1" />
<binding name="QuoteSoap" />
<binding name="WebservicePrimusSoapBinding" />
</basicHttpBinding>
<customBinding>
<binding name="QuoteSoap12">
<textMessageEncoding messageVersion="Soap12" />
<httpTransport />
</binding>
</customBinding>
</bindings>
<client>
<endpoint
address="https://webservices.rrts.com/rating/ratequote.asmx"
binding="basicHttpBinding"
bindingConfiguration="RateQuoteSoap"
contract="RoadRunnerService.RateQuoteSoap"
name="RateQuoteSoap" />
<endpoint
address="http://services.echo.com/Quote.asmx"
binding="basicHttpBinding"
bindingConfiguration="QuoteSoap"
contract="EchoService.QuoteSoap"
name="QuoteSoap" />
<endpoint
address="http://services.echo.com/Quote.asmx"
binding="customBinding"
bindingConfiguration="QuoteSoap12"
contract="EchoService.QuoteSoap"
name="QuoteSoap12" />
<endpoint
address="http://api.shipprimus.com/"
binding="basicHttpBinding"
bindingConfiguration="WebservicePrimusSoapBinding"
contract="PrimusService.WebservicePrimusServicePort"
name="WebservicePrimusServicePort" />
</client>
</system.serviceModel>
</configuration>
The PrimusService is the one that is not working correctly, and the full error when I try to initialize the client like WebservicePrimusServicePortClient serviceClient = new WebservicePrimusServicePortClient("WebservicePrimusServicePort"); is
System.InvalidOperationException: Could not find endpoint element with name 'WebservicePrimusServicePort' and contract 'PrimusService.WebservicePrimusServicePort'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 name could be found in the client element.
I have also tried to simply initialize a BasicHttpBinding object using the binding name and the endpoint name with no luck (short variable names for readability)
BasicHttpBinding a = new BasicHttpBinding("QuoteSoap"); // Works fine
BasicHttpBinding b = new BasicHttpBinding("WebservicePrimusSoapBinding"); // Fails
BasicHttpBinding c = new BasicHttpBinding("WebservicePrimusServicePort"); // Fails
It throws no error for binding a, but binding b and c fail with the error:
System.Collections.Generic.KeyNotFoundException: No elements matching the key 'WebservicePrimusSoapBinding' were found in the configuration element collection.

While not a direct solution, I ended up just taking the information from the app.config and creating my own BasicHttpBinding and EndpointAddress objects in code. This is more of a workaround than a fix for the problem, and I still don't know why I couldn't access the information in the app.config directly.
I followed the solution in this answer about how to consume a service without using the app.config file.
I created my BasicHttpBinding like
BasicHttpBinding binding = new BasicHttpBinding();
binding.Name = "PrimusServiceBinding"; // Completely Unnecessary
and my endpoint like
EndpointAddress endpoint = new EndpointAddress("http://api.shipprimus.com/");
and could connect to the service and retrieve information without a problem, even providing as little information as I did (basically just the address).

WCF exception--Faulted state

I added the WCF service reference to my project. Next step is to create a channel from the code.
WSHttpBinding bindingDialingType = new WSHttpBinding();
EndpointAddress endingPointDialingType = new EndpointAddress("http://wsvc.corporate.my.com/International/DialingService.svc");
ChannelFactory<IDialingService> iDialingServiceChannelFactory = new ChannelFactory<IDialingService>(bindingDialingType, endingPointDialingType);
IDialingService instanceIDialingService = iDialingServiceChannelFactory.CreateChannel();
Because I met an exception, so I guess that something wrong with my channel factory code.
The communication object, System.ServiceModel.Channels.ServiceChannel, cannot be used for communication because it is in the Faulted state.
To capture the exception, I had the code.
My app.config is:
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_iLuCRE" />
</basicHttpBinding>
<wsHttpBinding>
<binding name="WSHttpBinding_IDialingService">
<security mode="None" />
</binding>
</wsHttpBinding>
</bindings>
<client>
<endpoint address="http://wsvc.corporate.my.com/LuCRE/LuCRE.svc"
binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_iLuCRE"
contract="LuCRE.iLuCRE" name="BasicHttpBinding_iLuCRE" />
<endpoint address="http://wsvc.corporate.my.com/International/DialingService.svc"
binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IDialingService"
contract="DialingService.IDialingService" name="WSHttpBinding_IDialingService" />
</client>
</system.serviceModel>
I used WCFTestClient to test it, however the service does work. I added the service reference to my project and I don't know the code details.
Updated:
If I used the code
DialingServiceClient client = new DialingServiceClient();
Then call the method through client, then everything is fine. Why?

Your binding element security is None. You need to also mention it when defining programmatically.
WSHttpBinding bindingDialingType = new WSHttpBinding
{ Security = new WSHttpSecurity { Mode = SecurityMode.None } };

Reading endpoint from config file in workflow service

I know how can I read information from the config file in the activities by using C#
var servicesSection = (ClientSection)WebConfigurationManager.GetSection("system.serviceModel/client");
ChannelEndpointElement endpoint = servicesSection.Endpoints[0];
But when I try to read this information in the if statement of the workflow service, it doesn't work.
I tried the following code to read the endpoint information from the web.config file.
((ClientSection)WebConfigurationManager.GetSection("system.serviceModel/client")).Endpoints[0].toString().Equals("");
but it doesn't work.
some how, it doesn't understand the type casting and I can't convert the GetSection output to a clientSection object. do you know how can I do that in the if statement of the workflow service?( check something from the config file before calling some other activities)

I had similar requirement, after some prototyping, I managed following way. Hope this will help you and others.
/* Using in System.ServiceModel.dll */
using System.ServiceModel.Configuration;
using System.Web.Configuration;
/* Inside any method */
var clientSection = ((ClientSection)(WebConfigurationManager.GetSection("system.serviceModel/client")));
if (clientSection != null)
{
foreach (ChannelEndpointElement endPoint in clientSection.Endpoints)
{
..... endPoint.Name / endPoint.Address etc.
}
}
You can read any element from configuration and cast it to appropriate element type.

To read endpoint, binding and other sections from app.config, there are defined set of Section classes that help us read settings.
For example, to read list of bindings, we could simply use,
private void GetNetTcpBindingName()
{
Configuration appConfig = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
ServiceModelSectionGroup serviceModel = ServiceModelSectionGroup.GetSectionGroup(appConfig);
BindingsSection oBinding = serviceModel.Bindings;
List<BindingCollectionElement> bindingCollection = oBinding.BindingCollections;
NetTcpBindingCollectionElement netTCPBindingCollectionElement = (NetTcpBindingCollectionElement)bindingCollection.Where(obj => obj.BindingName.Equals("netTcpBinding")).SingleOrDefault();
if (netTCPBindingCollectionElement != null)
{
Console.WriteLine(netTCPBindingCollectionElement.ConfiguredBindings.ElementAt(0).Name);
}
}
Given the following app.config XML (section of interest in bold),
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_ITrainerManagement" />
</basicHttpBinding>
**<netTcpBinding>
<binding name="NetTcpBinding_ILiveStream">
<security mode="None" />
</binding>
</netTcpBinding>**
</bindings>
<client>
<endpoint address="net.tcp://sever-pc/PST.TS.LiveStream/LiveStream.svc"
binding="netTcpBinding" bindingConfiguration="NetTcpBinding_ILiveStream"
contract="LiveStreamServiceReference.ILiveStream" name="NetTcpBinding_ILiveStream" />
<endpoint address="http://10.5.50.115/PST.TS.TrainerService/TrainerManagement.svc"
binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_ITrainerManagement"
contract="TrainerManagementServiceReference.ITrainerManagement"
name="BasicHttpBinding_ITrainerManagement" />
</client>
</system.serviceModel>
Hope this helps. This can be used to read any standard settings.
