如何判别程序能否进行网络通信息

Question

服务器端引用如下
using System.Runtime.Remoting;
using System.Runtime.CompilerServices;
using System.Runtime.Remoting.Lifetime;
using TelBookLib;*.config.exe
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.runtime.remoting>
    <application name="TBookServer">
      <service>
        <wellknown mode="Singleton" type="TelBookInfo.TelBookImpl,tbookserver" objectUri="telephoneURI" />
      </service>      <channels>
        <channel ref="tcp" port="808">
          <serverProviders>
            <formatter ref="binary" typeFilterLevel='Full'/>  
            <!-- .NET框架1.1版本, 为序列化对象加上typeFilterLevel='Full'  -->
          </serverProviders>
        </channel>
      </channels>
    </application>
  </system.runtime.remoting>
</configuration>客户端引用如下
using System.Configuration;
using System.Runtime.Remoting;
using System.Runtime.CompilerServices;
using TelBookLib;*.config.exe
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
 <appSettings>
    <add key="bookURL" value="tcp://localhost:808/telephoneURI"/>
  </appSettings>  <system.runtime.remoting>
    <application name="TelBookClient">
      <channels>
        <channel ref="tcp" port="0">
           <clientProviders>
            <formatter ref="binary" />
          </clientProviders>
        </channel>
      </channels>
    </application>
  </system.runtime.remoting>
</configuration>能确定这在网上可以进行通信息吗？网络通信息必要的命名空间是什么
