我正在尝试使用简单的tcp客户端/服务器设置在两个编辑器之间传输一些数据:
服务器:

using System.Collections.Generic;

using System.Net.Sockets;

#endregion
// Use this for initialization

tcpListenerThread.Start();

SendMessage();
}

Byte[] bytes = new Byte[1024];
while (true) {
using (connectedTcpClient = tcpListener.AcceptTcpClient()) {
// Get a stream object for reading
using (NetworkStream stream = connectedTcpClient.GetStream()) {
int length;
// Read incomming stream into byte arrary.

// Convert byte array to string message.
string clientMessage = Encoding.ASCII.GetString(incommingData);
Debug.Log("client message received as: " + clientMessage);

}
}
catch (SocketException socketException) {
Debug.Log("SocketException " + socketException.ToString());
}

if (stream.CanWrite) {
string serverMessage = this.gameObject.transform.position.ToString();
// Convert string message to byte array.
byte[] serverMessageAsByteArray = Encoding.ASCII.GetBytes(serverMessage);
// Write byte array to socketConnection stream.
stream.Write(serverMessageAsByteArray, 0, serverMessageAsByteArray.Length);
Debug.Log("Server sent his message - should be received by client");
}
}

connectedTcpClient.Close ();

如果我在两台不同的计算机上单独运行服务器和客户端,这在本地工作但不会工作。此外,即使我从我的防火墙设置转发,我triennd ping.eu和我的端口似乎关闭。我做错了什么?
