.net - WCF:如何以编程方式重新创建这些 App.config 值？

Question

如果我创建服务而不指定任何绑定(bind)或端点(当我通过 Visual Studio 注册 WCF 时，它从 App.config 中生成的值中读取它)，我有一个工作正常的 WCF 服务。

我有一个返回服务引用的简单方法:

return new SmsServiceReference.SmsEngineServiceClient();

这工作正常(因为值是从配置中读取的)。但是，我想在数据库中包含其中一些值(例如 URI)，并且想做这样的事情:

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

        return new SmsServiceReference.SmsEngineServiceClient(binding,endpointAddress);

这行不通。当我尝试使用服务引用时，它会引发异常。

我怀疑这是因为我的 App.config 有更多信息，而这两行没有提供(显然)。问题是，如何以编程方式复制以下 App.Config 值？

这是我的 App.Config 的片段:(URI 已被更改以保护无辜者)。

  <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(bind)中的属性，可以通过编程方式重新创建。就个人而言，我使用如下方法来创建绑定(bind)

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);
