Read WCF service endpoint address by name from web.config
(3 answers)
Closed 1 year ago.
I have asp.net web application and have the following in my app.config file.
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="Test" />
<binding name="Test1">
<security mode="Test" />
</binding>
<binding name="BasicHttpBinding_IService1" />
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://test:90001"
binding="basicHttpBinding" bindingConfiguration="Test"
contract="Test" name="HTTP_Port" />
</client>
</system.serviceModel>
How i can get/read endpoint address value?
I have come accross the this solution but it is not working for me asking for exe file path. Not sure which exe path file?
var serviceModel = ServiceModelSectionGroup.GetSectionGroup(ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None));
var endpoints = serviceModel.Client.Endpoints;
foreach (ChannelEndpointElement e in endpoints)
{
if (e.Name == "HTTP_Port")
Console.WriteLine(e.Address);
}
Console.ReadLine();
To read endpoints from appconfig you need to add reference of System.ServiceModel.Configuration and use GetSectionGroup method which return the serviceModel group and you can access all the endpoints in that section,if you just need the one you can access specific with the endpoint name.
Also in the appconfig you provided the port is invalid, I got and error while reading the url with that port I assume you just added that as an example.

I had created an MVC application that had no authentication so I was advised to create a mvc project that has the 'Individual User Accounts' option selected which brings with it some controllers, models and views.
What I had done to keep my old class library data was rename the current class library as Projectold in my file explorer and created a new class library in Visual Studio with the same name(Project) then imported all the controllers, views, config files that I had from my previous library and included them in the new class library.
I have a proxy to 2 web services that exposes data for me to use. Because I only needed a new class library, I had the existing <system.serviceModel> tag already there in the existing service folder so I just copied and pasted it within the new web.config file in the new class library.
What has happened is that now I cannot access the web service to access the data. I am thrown the error:
System.InvalidOperationException
HResult=0x80131509
Message=Could not find endpoint element with name 'WebServiceSoap' and contract
'ProxyToWebService.WebServiceSoap' 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.

<Cannot evaluate the exception stack trace>
My web.config file is (The proxy URL's have been anonymised):
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="WebServiceSoap"/>
<binding name="SWebServiceSoap"/>
</basicHttpBinding>
<customBinding>
<binding name="WebServiceSoap12">
<textMessageEncoding messageVersion="Soap12"/>
<httpTransport/>
</binding>
<binding name="SWebServiceSoap12">
<textMessageEncoding messageVersion="Soap12"/>
<httpTransport/>
</binding>
</customBinding>
</bindings>
<client>
<endpoint address="http://URL/URL/URL.asmx" binding="basicHttpBinding" bindingConfiguration="WebServiceSoap" contract="ProxyToWebService.WebServiceSoap" name="WebServiceSoap" />
<endpoint address="http://URL/URL/URL.asmx" binding="customBinding" bindingConfiguration="WebServiceSoap12" contract="ProxyToWebService.WebServiceSoap" name="WebServiceSoap12" />
<endpoint address="http://URL/URL/URL.asmx" binding="basicHttpBinding" bindingConfiguration="SWebServiceSoap" contract="ProxyToSWebService.SWebServiceSoap" name="SWebServiceSoap" />
<endpoint address="http://URL/URL/URL.asmx" binding="customBinding" bindingConfiguration="SWebServiceSoap12" contract="ProxyToSWebService.SWebServiceSoap" name="SWebServiceSoap12" />
</client>
</system.serviceModel>
I have returned to a back up copy and it works before I replace my old new class library with my new class library so the endpoint connections should be okay. Just when they are used in the new class library is where it breaks.
I cannot just copy the old web.config file either as because the Individual User Accounts option is selected, it has modified the web.config file.
My code for the proxy connection:
public InboundService()
{
proxy = new WebServiceSoapClient("WebServiceSoap", "http://URL/URL/URL.asmx");
Sproxy = new SWebServiceSoapClient("SWebServiceSoap", "http://URL/URL/URL.asmx");
}
i have an WCF Service where some commands can run insecure via HTTP, but as soon as payment is done, I need to switch to TLS 1.2.
I see there is no way to get this working, except to add reference to second service with another binding and addionally changing the namespaces.
Is there no other way where I can use the same service and just switch the binding?
I use .NET 4.6.1 in case there is a feature in newer versions...
thx!
You can define the host as having multiple bindings and endpoints and the client too. Something like this in pseudo code, you have to fill in your own settings.
<netTcpbinding>
<binding name="notsecure">
<security mode="None" />
</binding>
<binding name="secure">
<security mode="Transport" /> <!-- desired security settings -->
</binding>
</netTcpBinding>
<services>
<service name="yyy">
<endpoint binding="netTcpbinding" bindingConfiguration="notsecure" name="insecureEnd"
contract="IContract" />
<endpoint binding="netTcpBinding" bindingConfiguration="secure"
name="secureEnd" contract="IContract" />
<host>
<baseAddresses>
<add baseAddress="xxx" />
</baseAddresses>
</host>
</service>
</services>
Then config your client with the same multiple bindings and multiple endpoints.
And in code select the correct endpoint by name
Client secure = new Client("secure");
secure.Call();
Client notsecure = new Client("notsecure");
You can use the PrincipalPermission attribute to let certain functions only be called when they are authenticated with a specific certificate.
From MSDN:
https://msdn.microsoft.com/en-us/library/ms731200(v=vs.110).aspx
[PrincipalPermission(SecurityAction.Demand, Name = "CN=ReplaceWithSubjectName; 123456712345677E8E230FDE624F841B1CE9D41E")]
public double Multiply(double a, double b)
{
return a * b;
}
In a C# service i must add a Web Service reference for calling some metods.
The testing URL use an HTTPS protocol, so I'm try to edit my endpoint to call new address:
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="fooSoap" />
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://x.x.x.x/WS_Foo/Foo.asmx"
binding="basicHttpBinding" bindingConfiguration="fooSoap"
contract="WSFooReferences.fooSoap" name="fooSoap" />
</client>
</system.serviceModel>
And so, I'm trying to call my method in c#:
WSFooReferences.fooSoapClient fooWS = new WSFooReferences.fooSoapClient();
int iRetCode = fooWS.Ping("ID12345");
But I've this error:
The provided URI scheme 'http' is invalid; expected 'https'
How I can edit my endpoint configuration fot this case?
T'ks!
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).
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.
