TcpClient缓冲区大小限制？ [英] TcpClient buffer size limit?

问题描述

我正在使用TcpClient并通过以下方式获取Stream：

TcpClient tcpclnt = new TcpClient（）;

。 。 。

流stm = tcpclnt.GetStream（）;


现在，当我试图通过stm.Write发送一个大缓冲区时（... 。）我得到一个

异常，说缓冲区太大。


我试图将tcpclnt.ReceiveBufferSize设置为缓冲区I的大小。 m

试图发送，但异常仍然被抛出，没有传输

缓冲区我可以设置。


如何我可以解决这个问题，除了分割我的缓冲区并通过

块发送它吗？

缓冲区的限制是什么？

I''m using TcpClient and getting the Stream by:
TcpClient tcpclnt = new TcpClient();
. . .
Stream stm = tcpclnt.GetStream();

Now, when I''m trying to send a big buffer via stm.Write(...) I get an
exception saying that the buffer is too big.

I tried to set the tcpclnt.ReceiveBufferSize to the size of the buffer I"m
trying to send, but the exception is still thrown, there is no transmit
buffer I can set.

How can I solve this problem beside splitting my buffer and transmit it by
chunks?
What is the limit of the buffer?

推荐答案

hi sharon，

奇怪的错误，您可以发布代码部分吗？


写入不需要创建新的缓冲区，它已经创建了。

欢呼，

hi sharon,
weird error, could you post the code section ?

Write do not need to create a new buffer, it;s already created.

cheers,

好的，这是代码：


//////////////////

//客户：

//////////////////

TcpClient tcpclnt = new TcpClient（）;

tcpclnt.Connect（" ip address"，8001）;

byte [] rowData = new byte [104857600]; // 100 MByte

tcpclnt.ReceiveBufferSize = rowData.Length;

Stream stm = tcpclnt.GetStream（）;

stm.Write（rowData，0，rowData.Length）; //抛出一个EXCEPTION !!!

//收到Ack。

ack =新字节[100];

k = stm.Read（ ack，0，ack.Length）;

tcpclnt.Close（）;


/////////////// ///

// Serevr：

//////////////////

ASCIIEncoding encoding = new ASCIIEncoding（）;

IPAddress ipAd = IPAddress.Parse（" ip address"）; //与

客户端使用的IP地址相同。 />
TcpListener myList = new TcpListener（ipAd，8001）;

myList.Start（）;

Socket sock = myList.AcceptSocket（）;

byte [] rowData = new byte [104857600]; // 100 MByte

recLen = sock.Receive（rowData）; //抛出一个EXCEPTION !!!

sock.Close（）;

myList.Stop（）;

////// /////////////////////


有什么想法吗？

OK, here is the code:

//////////////////
// The client:
//////////////////
TcpClient tcpclnt = new TcpClient();
tcpclnt.Connect("ip address", 8001);
byte [] rowData = new byte[104857600];// 100 MByte
tcpclnt.ReceiveBufferSize = rowData.Length;
Stream stm = tcpclnt.GetStream();
stm.Write(rowData, 0, rowData.Length); // throwing an EXCEPTION !!!
// Receiving Ack.
ack = new byte[100];
k = stm.Read(ack, 0, ack.Length);
tcpclnt.Close();

//////////////////
// The Serevr:
//////////////////
ASCIIEncoding encoding = new ASCIIEncoding();
IPAddress ipAd = IPAddress.Parse("ip address");// Same IP address as the
clients uses.
TcpListener myList = new TcpListener(ipAd, 8001);
myList.Start();
Socket sock = myList.AcceptSocket();
byte [] rowData = new byte[104857600];// 100 MByte
recLen = sock.Receive(rowData); // throwing an EXCEPTION !!!
sock.Close();
myList.Stop();
///////////////////////////

Any idea ?

hi sharon


我得到了同样的错误，这是我第一次看到它，你有多少内存呢？
？我只有512并且当我创建两个

缓冲区时我报告了大约800个但是在发送之前，可能缓冲区太大了，我认为你这个b $ b应该做一个谷歌搜索，看看是否有人之前有这个错误

抱歉无法为你提供进一步的帮助:(


欢呼，

hi sharon

I got the same error, this is the first time I see it, how many memory do
you have? I only have 512 and I got reported around 800 when I create both
buffers but before send it, maybe the buffer is too big, I think that you
should do a google search to see if anybody has got this error before
Sorry not be able to help you further :(

cheers,
