void
 CloseSocket(Socket socket)
         { 
             CloseSocket(socket, 
true
);
         }
private
 
void
 CloseSocket(Socket socket, 
bool
 shutdown)
         { 
if
 (socket 
!=
 
null
)
             { 
if
 (shutdown)
                 { 
                     socket.Shutdown(SocketShutdown.Both);
                 }
                 socket.Close();
             }
         }

B：创建中转Socket及建立连接

          
#region
 创建中转Socket及建立连接
             IPEndPoint ipEndpoint 
=
 
new
 IPEndPoint(ipAddress, port);
             Socket IPsocket 
=
 
new
 Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
try
             { 
                 IPsocket.Connect(ipEndpoint); Write(
"
-----Socket 建立连接！ IP地址：
"
 
+
 ipAddress 
+
 
"
网址：http://
"
 
+
 host);
             }
catch
 (Exception err)
             { 
                 Write(
"
连接失败 ：
"
 
+
 err.Message);
                 Write(
"
退出请求!!!
"
);
                 CloseSocket(IPsocket, 
false
);
return
;
             }  
#endregion

C：QQ代理测试及网页转发

            
if
 (isConnect)
//
QQ链接方式
            { 
byte
[] qqOkData 
=
 QQokProxyData();
                 clientSocket.Send(qqOkData, 
0
, qqOkData.Length, 
0
);
             }
else
//
正常网页，直接转发
            { 
                 IPsocket.Send(sendBytes, 
0
);
             }

函数分解：QQokProxyData

        
private
 
byte
[] QQokProxyData()
         { 
string
 data 
=
 
"
HTTP/1.0 200 Connection established
"
;
//
返回建立成功";
            
return
 System.Text.Encoding.ASCII.GetBytes(data);
         }

D：针对QQ需要进行重复来回的发送与接收

          
#region
 QQ发送/接收中转请求
int
 length 
=
 
0
, count 
=
 
0
;
if
 (isConnect)
             { 
                System.Threading.Thread.Sleep(
400
);
//
关键时延
//
循环发送客户端请求,接收服务器返回
                DateTime start 
=
 DateTime.Now;
while
 (
true
)
                { 
if
 (IPsocket.Available 
==
 
0
 
&&
 clientSocket.Available 
==
 
0
)
                     { 
if
 (((TimeSpan)(DateTime.Now 
-
 start)).TotalMinutes 
>
 
15
)
                         { 
break
;
//
掉线重拔处理
                        }
                     }
else
                     { 
                         start 
=
 DateTime.Now;
                     }
try
                     { 
while
 (clientSocket.Available 
!=
 
0
)
                         { 
                             sendLength 
=
 clientSocket.Receive(qqSendBytes, qqSendBytes.Length, 
0
);
                             IPsocket.Send(qqSendBytes, sendLength, 
0
);
                             Write(
"
发送字节数: 
"
 
+
 sendLength.ToString());
                         }
                         System.Threading.Thread.Sleep(
500
);
while
 (IPsocket.Available 
!=
 
0
)
                         { 
                             recvLength 
=
 IPsocket.Receive(qqRecvBytes, qqRecvBytes.Length, 
0
);
                             clientSocket.Send(qqRecvBytes, recvLength, 
0
);
                             Write(
"
接收字节数: 
"
 
+
 recvLength.ToString());
                        }
                     }
catch
                     { 
                     }
                 }
             }
else
             { 
try
                 { 
do
                     { 
                         length 
=
 IPsocket.Receive(recvBytes, count, IPsocket.Available, 
0
);
                         count 
=
 count 
+
 length;
                         Write(
"
接收转发请求返回的数据中...
"
 
+
 length);
                         System.Threading.Thread.Sleep(
200
);
//
关键点,请求太快数据接收不全
                    }
while
 (IPsocket.Available 
>
 
0
);
                     clientSocket.Send(recvBytes, 
0
, count, 
0
);
                 }
catch
(Exception err)
                 { 
                     Write(err.Message);
                 }
             }
#endregion

E：结束请求,关闭客户端Socket

            
#region
 结束请求,关闭客户端Socket
             Write(
"
接收完成。返回客户端数据...
"
 
+
 count);
             CloseSocket(IPsocket);
             CloseSocket(clientSocket);
             recvBytes 
=
 
null
;
             Write(
"
本次请求完成,已关闭连接...
"
);
             Write(
"
-----------------------------请求结束---------------------------
"
);
#endregion

结言：

本QQ代理软件在服务器上运行长达三个多月,使用过程未发现异常退出情况。当然前提就我一个人在用了
