使用WCF服务的代码配置替换app.config中的配置

Question

I'm trying to connect to DevelpmentService of MS CRM from custom plugin and thus I'm not able to use app.config generated when I added WebReference to solution.

Here is the working code:

var id = new EntityInstanceId
{
    Id = new Guid("682f3258-48ff-e211-857a-2c27d745b005")
};

var client = new DeploymentServiceClient("CustomBinding_IDeploymentService");

var organization = (Organization)client.Retrieve(DeploymentEntityType.Organization, id);

And corresponding part of the app.config :

<client>
    <endpoint address="http://server/XRMDeployment/2011/Deployment.svc"
        binding="customBinding" bindingConfiguration="CustomBinding_IDeploymentService"
        contract="DeploymentService.IDeploymentService" name="CustomBinding_IDeploymentService">
        <identity>
            <userPrincipalName value="DOMAIN\DYNAMICS_CRM" />
        </identity>
    </endpoint>

    ...

</client>

Is it possible to transform code in the way when configuration file will not be needed. How?

Answer 1

Yes, you can perform all of your web service, or client, configuration in code using either VB or C#. In some ways, really, it's better to configure in code since your code can be written to configure dynamically based on variables or existing conditions.

Basically, you can do something like this:

//end point setup
System.ServiceModel.EndpointAddress EndPoint = new System.ServiceModel.EndpointAddress("http://Domain:port/Class/Method");
System.ServiceModel.EndpointIdentity EndpointIdentity = default(System.ServiceModel.EndpointIdentity);

//binding setup
System.ServiceModel.BasicHttpBinding binding = default(System.ServiceModel.BasicHttpBinding);

binding.TransferMode = TransferMode.Streamed;
//add settings
binding.MaxReceivedMessageSize = int.MaxValue;
binding.ReaderQuotas.MaxArrayLength = int.MaxValue;
binding.ReaderQuotas.MaxBytesPerRead = int.MaxValue;
binding.ReaderQuotas.MaxDepth = int.MaxValue;
binding.ReaderQuotas.MaxNameTableCharCount = int.MaxValue;
binding.MaxReceivedMessageSize = int.MaxValue;
binding.ReaderQuotas.MaxStringContentLength = int.MaxValue;

binding.MessageEncoding = WSMessageEncoding.Text;
binding.TextEncoding = System.Text.Encoding.UTF8;
binding.MaxBufferSize = int.MaxValue;
binding.MaxBufferPoolSize = int.MaxValue;
binding.MaxReceivedMessageSize = int.MaxValue;
binding.SendTimeout = new TimeSpan(0, 10, 0);
binding.ReceiveTimeout = new TimeSpan(0, 10, 0);

//setup for custom binding
System.ServiceModel.Channels.CustomBinding CustomBinding = new System.ServiceModel.Channels.CustomBinding(binding);

What I do to configure my contract:

[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0"), System.ServiceModel.ServiceContractAttribute(Namespace = "http://MyNameSpace", ConfigurationName = "IHostInterface")]
public interface IHostInterface
{
}

this is working on my live environment

public static TResult UseService<TChannel, TResult>(string url,
                                                    EndpointIdentity identity,
                                                    NetworkCredential credential,
                                                    Func<TChannel, TResult> acc)
{
    var binding = new BasicHttpBinding();
    binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
    binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Windows;
    var endPointAddress = new EndpointAddress(new Uri(url), identity,
                                              new AddressHeaderCollection());
    var factory = new ChannelFactory<T>(binding, address);
    var loginCredentials = new ClientCredentials();
    loginCredentials.Windows.ClientCredential = credentials;

    foreach (var cred in factory.Endpoint.EndpointBehaviors.Where(b => b is ClientCredentials).ToArray())
        factory.Endpoint.EndpointBehaviors.Remove(cred);

    factory.Endpoint.EndpointBehaviors.Add(loginCredentials);
    TChannel channel = factory.CreateChannel();
    bool error = true;
    try
    {
        TResult result = acc(channel);
        ((IClientChannel)channel).Close();
        error = false;
        factory.Close();
        return result;
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.ToString());
        return default(TResult);
    }
    finally
    {
        if (error)
            ((IClientChannel)channel).Abort();
    }
}

where Identity = new SpnEndpointIdentity("") and Credentials = new NetworkCredential("User", "Pass", "server")

usage

NameSpace.UseService("http://server/XRMDeployment/2011/Deployment.svc",
                     Identity,
                     Credentials,
(IOrganizationService context) =>
{ 
   ... your code here ...
   return true;
});

this supposes windows Authentication and SpnEndpointIdentity witch have a very long base64 string I'm not sure if you have this case.

in the catch you can do some error handling or retrial but on my case its not used.

It should work

 var id = new EntityInstanceId
 {
     Id = new Guid("682f3258-48ff-e211-857a-2c27d745b005")
 };

 var endpoint = new EndpointAddress(new Uri("http://server/XRMDeployment/2011/Deployment.svc"),
                    EndpointIdentity.CreateUpnIdentity(@"DOMAIN\DYNAMICS_CRM"));

 var login = new ClientCredentials();
 login.Windows.ClientCredential = CredentialCache.DefaultNetworkCredentials;

 var binding = new CustomBinding();

 //Here you may config your binding (example in the link at the bottom of the post)

 var client = new DeploymentServiceClient(binding, endpoint);

 foreach (var credential in client.Endpoint.Behaviors.Where(b => b is ClientCredentials).ToArray())
 {
     client.Endpoint.Behaviors.Remove(credential);
 }

 client.Endpoint.Behaviors.Add(login);
 var organization = (Organization)client.Retrieve(DeploymentEntityType.Organization, id);

Here you may find the example of using code instead of config file
