SocketFlags.None不起作用 [英] SocketFlags.None doesnot work
问题描述
我有关于通过套接字发送数据的问题。等待另一个
socket.send
// str = Encoding.ASCII.GetBytes（" hello"）;
socket.Send（str，0，str.Length，SocketFlags.None）;
socket.Receive（strincome，0，socket.Available，Socket Flags.None ）; //返回
向你问好
// str = Encoding.ASCII.GetBytes（" how_are_you"）;
socket.Send（str，0，str.Length，SocketFlags.None）;
socket.Receive（strincome，0，socket.Available， Socket Flags.None）; //返回
罚款
它像这样发送hellohow_are_you ，但这是错的，我怎么解决呢
？
提前谢谢
简单来说，你必须发送一个终结符或者在发送字符串之前
发送你要发送的字节数。
欢呼，

嗨伊格纳西奥，
没有这样的事情。当我按命令运行命令（调试）时，它正常工作
。

那是因为你逐行踩？
socket.Send （str，0，str.Length，SocketFlags.None）;
socket.Receive（strincome，0，socket.Available，Socket Flags.None）; //返回
向你问好
使用socket.Available是个问题。如果执行过快，
在远程客户端有时间实现
发送任何内容之前，接收将被调用。因此socket.Available = 0.并且立即收到
返回而不实际接收任何签名。然后继续发送
下一位。
我的猜测是，这一切都发生得如此之快，以至于它看起来像一个字符串
在远程端。

Hi , i have problem about sending data over socket . It waits for another
socket.send
// str = Encoding.ASCII.GetBytes("hello");
socket.Send(str,0,str.Length,SocketFlags.None);
socket.Receive(strincome,0,socket.Available,Socket Flags.None); // return
"hello to you "
// str =Encoding.ASCII.GetBytes( "how_are_you ");
socket.Send(str,0,str.Length,SocketFlags.None);
socket.Receive(strincome,0,socket.Available,Socket Flags.None);// return
"fine"
it sends like this "hellohow_are_you" , but it is wrong , how can i solve it
?
thanks in advance
Hi,
Simple, you have to either send a terminator or before sending the string
send the # of bytes you will send.
cheers,

Hi Ignacio ,
there is no such thing . when i run it command by command ( debug ) it works
correctly .

Is that because you are stepping through line by line?
socket.Send(str,0,str.Length,SocketFlags.None);
socket.Receive(strincome,0,socket.Available,Socket Flags.None); // return
"hello to you "
That use of socket.Available is the problem. If execution goes too quickly,
the receive will get called before the remote client has time to actually
send anything. Thus socket.Available = 0. And the receive immediately
returns without actually receiving anythign. It then goes on to send the
next bit.
My guess is, this is all happening so fast that it all looks like one string
on the remote end.
