两台计算机之间进行.NET远程处理时出现套接字错误

remoteobject remoting sockets .net c#

对于我们正在处理的项目,我们使用.NET remoting在服务器和客户端之间进行通信。到目前为止,我们使用本地主机和任意端口号在同一台机器上对其进行了测试,并对其进行了处理。但是,当在同一网络上的两台机器之间进行测试时,使用,主组件工作,但代理对象失败。

<setting name="ServerName" serializeAs="String">
    <value>192.168.1.141</value>
</setting>
<setting name="Port" serializeAs="String">
    <value>9932</value>
</setting>

客户端按如下方式设置远程处理对象:

_port = global::ConsoleClient.Properties.Settings.Default.Port;
_servername = global::ConsoleClient.Properties.Settings.Default.ServerName;

string url = "tcp://" + _servername + ":" + _port + "/Lobby";

try
{
    ChannelServices.RegisterChannel(new TcpClientChannel(), false);
    Lobby lobby = (Lobby)Activator.GetObject(
        typeof(Lobby), url);
}
catch (Exception e)
{
}

这很好,我们可以调用大厅对象上的方法。但是,稍后在代码中,我们将返回另一个对象,表如下:

table_proxy = lobby_proxy.joinTable(userID, i);

_port = global::Server.Properties.Settings.Default.Port;
_lobby = new Lobby(_db);

try
{
    TcpServerChannel channel = new TcpServerChannel(_port);
    ChannelServices.RegisterChannel(channel, false);
    RemotingConfiguration.RegisterWellKnownServiceType(typeof(Lobby),
            "Lobby", WellKnownObjectMode.Singleton);
    RemotingServices.Marshal((_lobby), "Lobby");
    System.Console.WriteLine("Press Any Key");
}
catch (Exception e)
{
    System.Console.WriteLine(e);
}

在同一台计算机上运行时,此操作正常,但在不同的计算机上运行时会引发以下错误:

System.Net.Sockets.SocketException (0x80004005): A socket operation was attempte

从上面看,有一个IP地址我不认识,它既不在网络上,也不在路由器的IP上。

有什么问题吗?非常感谢您的帮助!

您需要使用以下参数设置TcpServerChannel:

绑定到
指定服务器通道应绑定到的网络接口卡(NIC)的IP地址的字符串。默认值为System.Net.IPAddress.Any。

更新时间:

IDictionary properties = new Hashtable();
properties["port"] = 9932;
properties["bindTo"] = "192.168.1.141";
TcpServerChannel channel = new TcpServerChannel(properties, null);
ChannelServices.RegisterChannel(channel,  false);

我将检查以确保运行此代码的计算机具有有效的IP地址。
