C#的TCP通信
TCP是连接模型，如下：
服务器连接 服务器断开
↓ ↑
服务器接收→服务器处理→服务器发送
↑ ↓
客户端发送←客户端处理←客户端接收
↑ ↓
客户端连接 客户端断开
服务器代码如下：
//
ServerListen
TcpListener tcplistener
=
new
TcpListener(
int
.Parse(txtPort.Text));
tcplistener.Start();
byte
[] btServerReceive
=
new
byte
[
256
];
string
strServerReceive
=
string
.Empty;
//
Loop for Listen
while
(
true
)
{
TcpClient tcp
=
tcplistener.AcceptTcpClient();
NetworkStream ns
=
tcp.GetStream();
int
intReceiveLength
=
ns.Read(btServerReceive,
0
,btServerReceive.Length);
strServerReceive
=
UnicodeEncoding.Unicode.GetString(btServerReceive,
0
,intReceiveLength);
txtServerResult.AppendText(
"
ServerReceive:
"
+
strServerReceive
+
"
"
);
ns.Write(btServerReceive,
0
,btServerReceive.Length);
txtServerResult.AppendText(
"
ServerSend:
"
