接收3144字节TCP / IP套接字在调试模式期间，但在执行1024字节期间 [英] Receiving 3144 bytes TCP/IP socket During debug mode, but during excecution 1024 byte
问题描述
我通过TCP / IP套接字接收3144字节在调试模式期间，但在执行期间收到1024字节
为什么会发生
IPEndPoint ipEnd = new IPEndPoint（ipAdd，ipPort）;
套接字套接字=新套接字（AddressFamily.InterNetwork，SocketType.Stream，ProtocolType.Tcp）;
套接字。连接（ipEnd）;
byte [] sendData = Encoding.ASCII.GetBytes（" msg"）;
socket.Send（sendData）;
int byteLen = 4096;
byte [] RecData = new byte [byteLen];
DataLen = socket.Receive（RecData，0，RecData .Length，SocketFlags.None）;
I am Receiving 3144 bytes through TCP/IP socket During debug mode, but during excecution 1024 byte were received
Why it is happen
IPEndPoint ipEnd = new IPEndPoint(ipAdd, ipPort);
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
socket.Connect(ipEnd);
byte[] sendData = Encoding.ASCII.GetBytes("msg");
socket.Send(sendData);
int byteLen = 4096;
byte[] RecData = new byte[byteLen];
DataLen = socket.Receive(RecData, 0, RecData.Length, SocketFlags.None);
推荐答案
Raj，
你需要围绕你的接收呼叫建立一个循环。
由于您不知道在网络数据包中通过了多少字节，您将不得不等待整个消息通过。
这基本上是伪代码/ java组合。希望它会有所帮助。
Raj,
You need to build a loop around your call to Receive.
Since you have no idea of how many bytes make it through in a network packet, you''ll have to wait for the whole message to come through.
This is basically pseudo-code/java combined. Hopefully it''ll help.
是的，它运作良好。不使用socket.Available我们如何在套接字中找到可用的消息（数据）。
boolean msgComplete = false;
int start = 0;
while（！msgComplete）
{
int input = socket.Receive（RecData，start，（RecData.Length-start），SocketFlags 。没有）;
if（input = -1）
抛出新的异常（socket disconnect）;
else if（socket.Available！= 0）
start + = input;
else
msgComplete = true;
}
yes, it works good. Without using socket.Available how would we find available message(data) in the socket.
boolean msgComplete = false;
int start = 0;
while (! msgComplete)
{
int input = socket.Receive(RecData, start, (RecData.Length-start), SocketFlags.None);
if (input = -1)
throw new Exception("socket disconnect");
else if (socket.Available != 0)
start += input;
else
msgComplete = true;
}
如果不使用socket.Available，可以找到套接字中的可用字节。
How would the available bytes in the socket could be found without using "socket.Available".
