WCF: How can I programmatically recreate these App.config values?

Question

I have a WCF service that works ok if I create the service without specifying any binding or endpoint (it reads it from the generated values in the App.config when I registered the WCF via Visual Studio).

I have a simple method that returns the service reference:

return new SmsServiceReference.SmsEngineServiceClient();

This works ok (because the values are read from the config). However, I'd like to have some of these values in a Database (the URI for example) and would like to do something like this:

        Binding binding = new BasicHttpBinding();
        EndpointAddress endpointAddress = new EndpointAddress( "my.uri.com/service.svc" );

        return new SmsServiceReference.SmsEngineServiceClient(binding,endpointAddress);

This doesn't work. It throws an exception when I try to use the service reference.

I suspect that this is because my App.config has more information that the two lines up there are not providing (obviously). The question is, how can I replicate the following App.Config values programmatically?

Here's the fragment of my App.Config: (the URI has been altered to protect the innocent).

  <system.serviceModel>
<bindings>
  <basicHttpBinding>
    <binding name="BasicHttpBinding_ISmsEngineService" 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="http://www.myuri.com/Services/Services.svc/basic"
      binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_ISmsEngineService"
      contract="SmsServiceReference.ISmsEngineService" name="BasicHttpBinding_ISmsEngineService" />
</client>

Most of the values in the App config are also properties in the binding and can be recreated programatically. Personally, I use a method such as the one below to create the binding

 public static BasicHttpBinding CreateBasicHttpBinding()
        {
            BasicHttpBinding binding = new BasicHttpBinding();
            binding.AllowCookies = false;
            binding.ReceiveTimeout = new TimeSpan(0, 10, 0);
            binding.OpenTimeout = new TimeSpan(0, 1, 0);
            binding.SendTimeout = new TimeSpan(0, 1, 0);
            // add more based on config file ...
            //buffer size
            binding.MaxBufferSize = 65536;
            binding.MaxBufferPoolSize = 534288;
            binding.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard;

            //quotas
            binding.ReaderQuotas.MaxDepth = 32;
            binding.ReaderQuotas.MaxStringContentLength = 8192;
            // add more based on config file ...

            return binding;
        }

And I use something like this for creating my Endpoint address

public static EndpointAddress CreateEndPoint()
        {
            return new EndpointAddress(Configuration.GetServiceUri());
        }

The serviceUri will be the service URL such as http://www.myuri.com/Services/Services.svc/basic

Finally to create the service client

 Binding httpBinding = CreateBasicHttpBinding();
 EndpointAddress address = CreateEndPoint();
 var serviceClient = new MyServiceClient(httpBinding, address);

Answer 2

Well, the client endpoint in the config specifies this URL:

 <endpoint address="http://www.myuri.com/Services/Services.svc/basic"

but in your code sample, you create:

 EndpointAddress endpointAddress = new EndpointAddress( "my.uri.com/service.svc" );

The addresses must match - if the one in the config works, you'll need to change your code to:

 EndpointAddress endpointAddress = new EndpointAddress( "http://www.myuri.com/Services/Services.svc/basic" );

Mind you - there are various little typos in your code sample (my.uri.com vs. www.myuri.com, /service.svc instead of /Services/Services.svc).

Does it work with the corrected endpoint address?
