删除标准输出 [英] redicting standard output

问题描述

我有一个应用程序，我在其中创建一个Plink进程，用HP Unix盒子进行通信。我遇到的问题是，在阅读

重定向输出时，它似乎试图继续结束并获得无限循环中的
。我正在检查输出的结束

是这样的：


while（（hj = puttyProcess.StandardOutput.ReadLine（））！= null）


我做错了什么？


谢谢，


Zenon

什么我做错了吗？

你的意思是什么？继续走到尽头？


注意你应该也是在另一个线程中读取StandardError，

否则你可能会在尝试向stderr写入

时结束plink阻塞。

我想我假设线程正在读取空值

表示输出结束并被抓到那里。我怎么用
将StandardError读入另一个帖子？


感谢您的帮助

您有什么证据？你确定它不仅仅是因为plink还没有完成阻止吗？

如何将StandardError读入另一个线程？

创建一个可以访问Process引用的新线程，并且与你为StandardOutput做的完全相同，但对于

StandardError。

I have an application where I create a Plink process to communicate
with an HP Unix box. The problem I am having is that while reading the
redirected output, it seems to try to continue past the end and gets
caught in an endless loop. I am checking for the end of the output
like this:

while ((hj = puttyProcess.StandardOutput.ReadLine())!=null)

What am I doing wrong?

thanks,

Zenon

What do you mean by "continue past the end"?

Note that you should also be reading StandardError in another thread,
otherwise you could end up with plink blocking when it tries to write
to stderr.

I guess that I was assuming the thread was reading past the null which
signifies the end of the output and getting caught there. How do I
read StandardError into another thread?

thanks for your help

What evidence did you have for that? Are you sure it isn''t just
blocking because plink hasn''t finished?
How do I
read StandardError into another thread?

Create a new thread which has access to the Process reference, and do
exactly the same as you''re doing for StandardOutput, but for
StandardError.
