无法与服务沟通 [英] cant't comunicate with service
问题描述
您好,
我正在编写一项服务,应该通过TCP回复一些信息。
启动服务后一秒钟PC尝试连接该服务。
在服务的OnStart中,我创建了一个我的通信类的实例:
Hi There,
I am writing an service that should be reply some information via TCP.
After starting the service a second PC try to connect with the service.
In the OnStart of the service I create an instance of my comunication class with:
string urlService = "net.tcp://192.168.10.48:1234/MyService";
host = new ServiceHost(typeof(ServicePCBI));
host.Opening += new EventHandler(host_Opening);
host.Opened += new EventHandler(host_Opened);
host.Closing += new EventHandler(host_Closing);
host.Closed += new EventHandler(host_Closed);
NetTcpBinding tcpBinding = new NetTcpBinding(SecurityMode.None);
host.AddServiceEndpoint(typeof(IServiceTest), tcpBinding, urlService);
host.Open();
这部分代码运行并监听端口,我写的一个日志文件检查所有事件,看起来一切正常。
我检查了服务的IP(首先我有一个错误的IP,但没有大的改动来纠正这个)。 />
其中一项测试,不起作用
This part of code runs and listen to the port, I write an logfile to check all events and it looks like everything is ok.
I have checked the IP of the service (first I had an wrong IP, but was no big change to correct this).
Here one of the tests, that not work
Socket sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.IP);
IPAddress addr = IPAddress.Parse("192.168.10.48");
IPEndPoint endpoint = new IPEndPoint(addr, 1234);
AddToLogFile("start listen! ");
while (true)
{
sock.Bind(endpoint);
sock.Listen(10);
Socket client = sock.Accept();
AddToLogFile("Now ok! " + client.LocalEndPoint.ToString());
}
有谁知道为什么我不能连接服务中的套接字?
谢谢
Has anyone an idea why I can''t connect with the socket in the service?
Thanks
推荐答案
好吧它只是防火墙,关闭后一切正常。
这是一个很好的例子TCP连接:
TCP / IP服务器用C#编写 [ ^ ]
谢谢
Ok it was just the firewall, after turn off everything is working.
Here is one good example for TCP connection:
A TCP/IP Server written in C#[^]
Thanks
