我正在开发一个大型系统，为此我必须使用 WCF 来访问 Web 服务。我的测试代码工作正常，现在我需要将我的 WCF 客户端代码集成到更大的系统中。我无法添加到现有的“app.config”文件中，并且想指定一个单独的 .config 文件供我的客户端代码使用。

我怎样才能最好地做到这一点？

谢谢！

There are 2 options.

Option 1. Working with channels.

If you are working with channels directly, .NET 4.0 and .NET 4.5 has the ConfigurationChannelFactory. The example on MSDN looks like this:

ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap();
fileMap.ExeConfigFilename = "Test.config";
Configuration newConfiguration = ConfigurationManager.OpenMappedExeConfiguration(
    fileMap,
    ConfigurationUserLevel.None);

ConfigurationChannelFactory<ICalculatorChannel> factory1 = 
    new ConfigurationChannelFactory<ICalculatorChannel>(
        "endpoint1", 
        newConfiguration, 
        new EndpointAddress("http://localhost:8000/servicemodelsamples/service"));
ICalculatorChannel client1 = factory1.CreateChannel();

As pointed out by Langdon, you can use the endpoint address from the configuration file by simply passing in null, like this:

var factory1 = new ConfigurationChannelFactory<ICalculatorChannel>(
        "endpoint1", 
        newConfiguration, 
        null);
ICalculatorChannel client1 = factory1.CreateChannel();

This is discussed in the MSDN documentation.

Option 2. Working with proxies.

If you're working with code-generated proxies, you can read the config file and load a ServiceModelSectionGroup. There is a bit more work involved than simply using the ConfigurationChannelFactory but at least you can continue using the generated proxy (that under the hood uses a ChannelFactory and manages the IChannelFactory for you.

你不能随心所欲地做到这一点——你可以接近，但不能完全做到。

您可以做的是将此部分添加到主应用程序的配置文件中：

<system.serviceModel>
   <bindings configSource="bindings.config" />
   <behaviors configSource="behaviors.config" />
   <client configSource="client.config" />
   <services configSource="services.config" />
  .....
</system.serviceModel>

因此，对于内部的每个部分<system.serviceModel>，您可以使用该configSource=属性指定一个外部配置文件（并且不要让 Visual Studio 的红色波浪线混淆它 - 是的，它确实有效！）。

您可以对任何配置部分执行此操作- 但不幸的是，无法对整个部分组( <system.serviceModel>) 执行此操作。

不幸的是，WCF 中没有对此的内置支持。您必须自己创建自己的 ChannelFactory 子类并加载/解析配置文件。在 MSDN 论坛上查看这篇文章，了解更多实现细节。

或者，您可以用一种简单易行的方法来实现 - 并按照本文所述实现自定义配置文件，该文件使用 DataSet / DataTable 模型来存储/检索您的配置（包括工作代码）：

So the option mentioned by marc_s DOES work. Ignore Visual Studio warning that it doesn't recognize the configSource property on bindings and all other places.
