使用配置文件替代硬编码可使应用程序拥有更高的灵活性，尤其是对分布式系统而言，意味着我们可以非常方便地调整分布对象的配置。Remoting 的配置文件比较简单，详细信息可以参考 MSDN。

下面是个简单的例子，包含了 SAO / CAO 的配置样例。

Server.cs
BinaryClientFormatterSinkProvider cbin = new BinaryClientFormatterSinkProvider();
BinaryServerFormatterSinkProvider sbin = new BinaryServerFormatterSinkProvider();
sbin.TypeFilterLevel = TypeFilterLevel.Full;

Hashtable properties = new Hashtable();
properties["port"] = 801;

TcpChannel channel = new TcpChannel(properties, cbin, sbin);
ChannelServices.RegisterChannel(channel, false);

RemotingConfiguration.RegisterWellKnownServiceType(typeof(Data), "data", WellKnownObjectMode.Singleton);
RemotingConfiguration.ApplicationName = "test";
RemotingConfiguration.RegisterActivatedServiceType(typeof(Data2));

Client.cs
TcpChannel channel = new TcpChannel();
ChannelServices.RegisterChannel(channel, false);
RemotingConfiguration.RegisterWellKnownClientType(typeof(Data), "tcp://localhost:801/data");
RemotingConfiguration.RegisterActivatedClientType(typeof(Data2), "tcp://localhost:801/test");

Data data = new Data();
data.Test();

Data2 data2 = new Data2();
data2.Test();

改成对应的配置文件，就是下面这个样子。

Server.config
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.runtime.remoting>
    <application name="test">
      <channels>
        <channel ref="tcp" port="801">
          <clientProviders>
            <formatter ref="binary"/>
          </clientProviders>
          <serverProviders>
            <formatter ref="binary" typeFilterLevel="Full" />
          </serverProviders>
        </channel>
      </channels>
      <service>
        <wellknown mode="Singleton" type="Learn.Library.Remoting.Data, Learn.Library" objectUri="data" />
        <activated type="Learn.Library.Remoting.Data2, Learn.Library" />
      </service>
    </application>
  </system.runtime.remoting>
</configuration>

Client.config
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.runtime.remoting>
    <application>
      <channels>
        <channel ref="tcp">
          <clientProviders>
            <formatter ref="binary"/>
          </clientProviders>
        </channel>
      </channels>
      <client url="tcp://localhost:801/test">
        <wellknown type="Learn.Library.Remoting.Data, Learn.Library" url="tcp://localhost:801/data" />
        <activated type="Learn.Library.Remoting.Data2, Learn.Library" />
      </client>
    </application>
  </system.runtime.remoting>
</configuration>

Server.cs
RemotingConfiguration.Configure("server.config", false);

Client.cs
RemotingConfiguration.Configure("client.config", false);

Data data = new Data();
data.Test();

Data2 data2 = new Data2();
data2.Test();
