簡單的c# tcp通訊(tcplistener)
c# 的tcp socket (同步方式)
c# 的tcp socket (非同步方式)
c# 的tcp socket設定自定義超時時間
c# tcp socket傳送大資料報時,接收端和傳送端資料不一致 服務端接收receive不完全
伺服器端:
publicstatic manualresetevent alldone = new manualresetevent(false
);ipendpoint localendpoint = new ipendpoint(ipaddress.parse("
127.0.0.1
"), port);
socket listener = new
socket(addressfamily.internetwork, sockettype.stream, protocoltype.tcp);
listener.bind(localendpoint);
listener.listen(
30);
while (true
)
publicstatic
void
acceptcallback(iasyncresult ar)
}catch
(system.exception ex)
", ex.message);}}
private
static
void
receivehead(iasyncresult ar)
catch
(system.exception ex)
", ex.message +ex.stacktrace);
}}
publicstatic
void
readcallback(iasyncresult ar)
已知接收長度的話可以把receivehead函式去掉,直接進入readcallback裡。
加入receivehead是因為協議一般在開頭幾個固定的位元組裡有後面資料報的長度,所以先接收頭,再根據解析出的資料報長度接收後面的。
stateobject定義如下,可以不要headbuffer headbuffersize
