的TcpClient [英] TcpClient
问题描述
大家好，我正在使用TcpClient，它是通过
网络发送数据的流。
现在我注意到了我的应用程序正在使用大量内存，我注意到每次我需要通过网络发送内容时我会重新创建一个新的
TcpClient实例，而不是使用一个已经创建了。事情是
，如果我尝试使用一个已经创建的数据，那么数据就无法到达其他电脑。
我还有什么吗？我失踪了？我可以这样做吗？
TIA。
问候，

Hi all, I''m using a TcpClient and it''s stream to send data over a
network.
Now I''m noticing that my app is using a lot of memory, and I''ve noticed
that everytime I need to send something over the net I recreate a new
TcpClient instance instead of using one allready created. The thing is
that if I try to use one allready created the data does not reach the
other computer.
Is there anything I''m missing? Can I do that?
TIA.
Regards,
Sebastián Gómez

没有看到一些代码就很难说。你可以发一个简短但是
完整的例子来证明这个问题吗？请参阅

我的意思是什么。

It''s hard to say without seeing some code. Could you post a short but
complete example which demonstrates the problem? See
http://www.pobox.com/~skeet/csharp/complete.html
for what I mean by that.

好的，我会试着解释一下自己。
这里是班级客户
公共类客户
{
私有IPAddress ip;
[NonSerialized]私有TcpClient客户端;
私有字符串version;
private string userName;
private string realName;
private FileStream fileObj;
private string fileName;
}
在表单中我有一个客户端的ArrayList。
所以，每当我想向所有这些发送消息时客户我喜欢
这个：
foreach（客户中的客户c）
{
_client = new TcpClient（c.IP.ToString（），8080）; //每次创建新的TcpClient
StreamWriter stream = new StreamWriter（_client.GetStream（））;
stream。写（Hello World）;
stream.Flush（）;
}
这很好用，但是我想做的是这个
foreach（客户端的客户端c）
{
StreamWriter stream = new StreamWriter（c.tcpClient.GetStream） （））;
//导致客户端allready有一个TcpClient实例
stream.Write（Hello World）;
stream.Flush（）;
}
但这不起作用，也不会抛出任何例外，它只是
不会到达另一台电脑。
我希望它有助于理解我的问题。

Ok, I''ll try to explain myself.
Here''s the class Client
public class Client
{
private IPAddress ip;
[NonSerialized] private TcpClient client;
private string version;
private string userName;
private string realName;
private FileStream fileObj;
private string fileName;
}
In a form I have an ArrayList of Clients.
So whenever I want to send a message to all this Clients I go like
this:
foreach(Client c in clients)
{
_client = new TcpClient(c.IP.ToString(),8080); //Create new TcpClient
every time
StreamWriter stream = new StreamWriter(_client.GetStream());
stream.Write("Hello World");
stream.Flush();
}
This works just fine, but what I wish to do is this
foreach(Client c in clients)
{
StreamWriter stream = new StreamWriter(c.tcpClient.GetStream());
//Cause the client allready has an instance of a TcpClient
stream.Write("Hello World");
stream.Flush();
}
But this does not work, it won''t throw any exceptions either, It just
won''t reach the other computer.
I hope it helps understand my problem.

Sebastián

您应该只需要一个TcpClien与另一个同伴进行整个会话。
如果你创建另一个，你创建一个新的会话。

You should only need one TcpClient for the whole session with another peer.
If you create another one, your creating a new session.
