使用WCF服务的代码配置替换app.config中的配置

Question

我试图连接到DevelpmentService从自定义插件MS CRM的，因此我不能够使用app.config当我添加Web引用到溶液中生成。

这是工作代码：

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);

和app.config相应部分：

<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>

是否可以在不需要配置文件时转换代码。 怎么样？

Answer 1

是的，您可以使用VB或C＃在代码中执行所有Web服务或客户端配置。 在某些方面，实际上，最好在代码中进行配置，因为您的代码可以根据变量或现有条件动态配置。

基本上，你可以做这样的事情：

//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);

我做什么来配置我的合同：

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

这是在我的生活环境

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();
    }
}

其中Identity = new SpnEndpointIdentity("")和Credentials = new NetworkCredential("User", "Pass", "server")

用法

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

这假设windows身份验证和SpnEndpointIdentity有一个非常长的base64字符串我不确定你是否有这种情况。

在捕获中你可以做一些错误处理或重审，但在我的情况下它没有使用。

它应该工作

 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);

在这里，您可以找到使用代码而不是配置文件的示例
