Remoting 小问题。

Question

我现在要在服务器断监听多个端口
string[] str = 一个数组,包含如 "1542,1592,4584,4512,6545,5412"  .Split(',');;
            foreach (string iPort in str)
            {
                if (iPort.Trim() != "")
                {
                    try
                    {
                        TcpServerChannel tcpChannel = new TcpServerChannel("tcpChannel" + iPort, int.Parse(iPort));
                        RemotingConfiguration.RegisterWellKnownServiceType(typeof(CSAchieve.User), "Service" + iPort, WellKnownObjectMode.SingleCall);
                        ChannelServices.RegisterChannel(tcpChannel, false);
                        txtResult.Text += "端口:" + iPort + " 监听成功\r\n";
                    }
                    catch (Exception ex)
                    {
                        txtResult.Text += "端口:" + iPort + "监听失败,错误:" + ex.Message + "\r\n";
                    }
                }
            }

原来是使用app.config配置 使用单端口的
<system.runtime.remoting>
  <application name="CSKLSCCC">
   <service>
    <wellknown mode="SingleCall" type="CSKL.CSAchieve.User, CSKL.CSAchieve" objectUri="Service" />
   </service>
   <channels>
    <channel ref="tcp" port="4000">
     <serverProviders>
      <formatter ref="soap" typeFilterLevel="Full"/>
      <formatter ref="binary" typeFilterLevel="Full"/>
     </serverProviders>
    </channel>
   </channels>
  </application>
 </system.runtime.remoting>

现在该用上面的代码循环监听多个端口后，客户端请求原来的函数，提示找不到服务, 改回原来的单IP使用app.config配置来初始化
RemotingConfiguration.Configure(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile, false);
这样是正常的，看了半天没找到原因，请教各位大虾来了！

Answer 1

你好你这里 RemotingConfiguration.RegisterWellKnownServiceType(typeof(CSAchieve.User), "Service" + iPort, WellKnownObjectMode.SingleCall);
采用了对象 URI 是"Service”+iPort 而在你的服务器上的配置
<service>
    <wellknown mode="SingleCall" type="CSKL.CSAchieve.User, CSKL.CSAchieve" objectUri="Service" />
   </service>

却只有Service 因而会出错

 晕，那如果我要同时监听几十个端口那不是要玩死人了。。。而且端口很可能是动态配置的，监听那么多端口是很有可能的。项目需求！
我个人以为 使用 RemotingConfiguration.RegisterWellKnownServiceType(typeof(CSAchieve.User), "Service" + iPort, WellKnownObjectMode.SingleCall);
就能代替了 <service>
    <wellknown mode="SingleCall" type="CSKL.CSAchieve.User, CSKL.CSAchieve" objectUri="Service" />
   </service>
所以那样写。。。汗！有没有能用代码的解决方法，配置文件这样写，不大现实！

而且我在监听多端口的时候，app.config 内的 是直接删除了的。他也没报错啊！
<serverProviders>
      <formatter ref="soap" typeFilterLevel="Full"/>
      <formatter ref="binary" typeFilterLevel="Full"/>
     </serverProviders>
除了 这个，我在代码内没找到方法指定。我猜想会不会是这个原因！而且 如果使用app.config 来配置
RemotingConfiguration.Configure(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile, false);

这样去注册的话，很麻烦的！

Answer 4

你监听这么多端口做什么？用socket一个端口就可以搞定。IIS就是这么处理http请求的。

您好，做如下修改，请参考：
1、服务器端监听多个端口，而服务注册一个即可。把RemotingConfiguration.RegisterWellKnownServiceType拿出来。
foreach (string iPort in str)
            {
                if (iPort.Trim() != "")
                {
                    try
                    {
                        TcpServerChannel tcpChannel = new TcpServerChannel("tcpChannel" + iPort, int.Parse(iPort));
                       ChannelServices.RegisterChannel(tcpChannel, false);
                        txtResult.Text += "端口:" + iPort + " 监听成功\r\n";
                    }
                    catch (Exception ex)
                    {
                        txtResult.Text += "端口:" + iPort + "监听失败,错误:" + ex.Message + "\r\n";
                    }
                }
            }
 RemotingConfiguration.RegisterWellKnownServiceType(typeof(CSAchieve.User), "Service" , WellKnownObjectMode.SingleCall);

                       
2、客户端用不同端口的url来访问即可。
