WCF:我如何以编程方式重新创建这些App.config值？

Question

我有一个WCF服务,如果我创建服务时没有指定任何绑定或端点(当我通过Visual Studio注册WCF时从App.config中生成的值读取它).

我有一个返回服务引用的简单方法:

return new SmsServiceReference.SmsEngineServiceClient();

这工作正常(因为从配置中读取值).但是,我想在数据库(例如URI)中有一些这些值,并希望这样做:

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

        return new SmsServiceReference.SmsEngineServiceClient(binding,endpointAddress);

这不起作用.当我尝试使用服务引用时,它会抛出异常.

我怀疑这是因为我的App.config有更多信息,其中两条线路没有提供(显然).问题是,如何以编程方式复制以下App.Config值？

这是我App.Config的片段:( URI已被修改以保护无辜者).

  <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>

App配置中的大多数值也是绑定中的属性,可以以编程方式重新创建.就个人而言,我使用下面的方法来创建绑定

 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;
        }

我使用这样的东西来创建我的端点地址

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

serviceUri将是服务URL,例如http://www.myuri.com/Services/Services.svc/basic

最后创建服务客户端

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