异步套接字接收确切数量的数据示例? [英] Async Socket Receive Exact amount of data Example?

问题描述

嗨

我在确定如何接收确切数量的

Im having a bit of a problem working out how to receive an exact amount of

数据.我想接收确切数据的原因是，我有一个头，我从服务器接收到该头，该头具有数据的大小，然后从接收到的大小中，我可以算出我想要的确切数据量使用.

data. the reason i want to receive the exact amount of data is that i have a header that i recieve from a server this header has the size of the data then from the size received i can work out the exact amount of data i want to use.

所以问题是我如何指定要接收的数据量?

so the question is how can i specify the amount of data that i want to receive?

我尝试了以下示例，但是onrecieve回调将接收增量的数据. 数据.

I have tried the below example but the onrecieve callback would recieve incremented amounts of data.

// use OnRecieve callback
psSocket.BeginReceive(buffer, 0, buffer.Length, SocketFlags.None, new AsyncCallback(this.OnReceive), this.m_psSocket);

// callback
private void OnReceive(IAsyncResult ar)
{
Socket clientSocket = (Socket)ar.AsyncState;

            int bytesRead = clientSocket.EndReceive(ar);

            if (bytesRead > 0)
            {

            }

}

谢谢

推荐答案

也有一个类似于beginforceivemessagefrom的功能，用于TCP异步套接字

also is there a function similar to beginreceivemessagefrom for TCP async socket
