C# Socket 由于目标计算机积极拒绝，无法连接

最初的梦想zsq 2016-10-18 04:08:56





   private static Socket ConnectSocket(string server, int port)

        {

            Socket socket = null;                       //实例化Socket对象，并初始化为空

            IPHostEntry iphostentry = null;                         //实例化IPHostEntry对象，并初始化为空

            iphostentry = Dns.GetHostEntry(server);                           //获得主机信息

            //循环遍历得到的IP地址列表

            foreach (IPAddress address in iphostentry.AddressList)

            {

                //使用指定的IP地址和端口号实例化IPEndPoint对象

                IPEndPoint IPEPoint = new IPEndPoint(address, port);

                //使用Socket的构造函数实例化一个Socket对象，以便用来连接远程主机

                Socket newSocket = new Socket(IPEPoint.AddressFamily, SocketType.Stream, ProtocolType.Tcp);

                newSocket.Connect(IPEPoint);                                //调用Connect方法来连接远程主机

                if (newSocket.Connected)

                {

                    socket = newSocket;

                    break;

                }

                else

                {

                    continue;

                }

            }

            return socket;

        }



        //获取指定服务器的主页面内容

        private static string SocketSendReceive(string server, int port)

        {

            string request = "GET/HTTP/1.1\n 主机："+server+"\n  连接：关闭 \n";

            Byte[] btSend = Encoding.ASCII.GetBytes(request);

            Byte[] btReceived=new Byte[256];

            //调用自定义方法ConnectSocket          使用指定的服务器名和端口号实例化一个Socket对象

            Socket socket = ConnectSocket(server,port);

            if (socket == null)

            {

                return ("连接失败！");

            }

            //将请求发送到连接的服务器

            socket.Send(btSend,btSend.Length,0);

            int intContent = 0;

            string strContent = server + " 上的默认页面内容:\n";

            do

            {

                //从绑定的Socket接收数据

                intContent = socket.Receive(btReceived,btReceived.Length,0);

                //将接收到的数据转换为字符串类型

                strContent += Encoding.ASCII.GetString(btReceived,0,intContent);



            } while (intContent>0);



            return strContent;

        }

调用以上方法

string HostName = "192.168.1.97";
int HostNumer = 80;

string strContent = SocketSendReceive(HostName,HostNumer);
Console.WriteLine(strContent);

希望大神帮我看看，我试过把防火墙关闭，安全软件关闭，可还是不行。
新接触Socket 方面。望指教。
