TCP套接字-发送和接收问题 [英] TCP Socket - Send and receive question

问题描述

你好，

我正在尝试使用.net中的异步套接字发送消息并接收响应.在一个函数中，我执行以下操作

1.通过套接字发送消息
2. while(fullresponserecieved)= false，保持状态，当我收到0个字节(或消息末尾)时，此变量变为true.
3.然后执行其余功能.

我认为这导致线程出现问题.线程执行函数和异步套接字线程.这是正确的方法吗?还是我应该使用阻塞线程?可能需要一些时间才能收到整个响应，最多可能需要1分钟，我不希望我的应用在这段时间内没有响应.

谢谢，

Hello,

I am trying to send a message and receive a response using asynchonous sockets in .net. In a function I do the following

1. Send a message thru the socket
2. While(fullresponserecieved)=false, this holds state, this variable turns to true while I receive 0 bytes(or end of message).
3. Then I execute the rest of my function.

I think this is causing a problem with the threads. The thread executing function and the asynchronous socket threads. Is this the correct way to do this? Or should I be using a blocking thread? It may take some time to receive the entire response, up to about 1 minute, I wouldn''t want my application to become unresponsive for that period of time.

Thanks,

推荐答案

在我看来，线程使异步API变得多余.异步调用无论如何应该间接产生一个线程，或者具有等效的功能.将线程与同步阻塞调用一起使用是更直接，更可靠和更可靠的方法.

In my strong opinion, threads make asynchronous APIs redundant. Asynchronous calls should spawn a thread indirectly anyway, or have equivalent functionality. Using threads with synchronous blocking calls is more straightforward, robust and reliable way.
