如何正确和完全关闭/重置一个TcpClient的连接？ [英] How to properly and completely close/reset a TcpClient connection?

问题描述

什么是关闭或重置一个TcpClient的连接的正确方法是什么？ 我们的软件与硬件，但有时一些沟通 出了问题，我们不再与它交流，直到我们重新启动软件。

What is the correct way to close or reset a TcpClient connection? We have software that communicates with hardware but sometimes something goes wrong and we are no longer to communicate with it, until we restart the software.

我试图迫使TcpClient.Close（），甚至将其设置为空，但不起作用。 软件只能一个完整的重新启动。

I have tried forcing TcpClient.Close() and even setting it to null but that doesn't work. Only a complete restart of the software works.

建议？

我不能使用using关键字，因为TpcClient只在一个位置定义，而且在整个库中使用。 （而且只有一个在任何给定时间连接）

I can't use the using keyword because TpcClient is only defined in one location, but used throughout the library. (And there is only one connection at any given time)

这是处理通信库。软件本身可以调用控制器类的ResetConnection（）方法（它重新presents硬件）。

It's a library that handles communication. The software itself can call the ResetConnection() method of the Controller class (which represents the hardware).

目前，它看起来像

if (tcpClient != null)
{
    tcpClient.Close();
    tcpClient = null;
}

现在从我读到这里，我应该使用，而不是=空

Now from what I've read here I should use tcpClient.Dispose() instead of " = null"

我会给一个尝试，看看它是否有差别。

I'll give that a try and see if it makes a difference.

推荐答案

您必须关闭连接前关闭流：

You have to close the stream before closing the connection:

tcpClient.GetStream().Close();
tcpClient.Close();

关闭客户端不会关闭该流。

Closing the client does not close the stream.
