C＃Process.Start（应用程序将代码返回给OS） [英] C# Process.Start (applications return code to OS)

问题描述

我正在运行一个名为AcroComm.exe的应用程序来查询我们公司的b / b
时钟。我写了一个小的C＃应用​​程序，根据数据库中的信息，基于

轮询时钟。我的问题是AcroComm有时会在进程中间停止轮询并终止。该应用程序的编程说明它会在操作系统完成后发送一个代码来完成操作系统，它会告诉我们发生了什么，如下所示：


0成功

13 aborted

等...


当它中止下载时，我的程序不知道它，它只是转到下一行代码的
并继续轮询下一个时钟。我正在使用代码

，如下所示：System.Diagnostics.Process.Start（" AppPath\Name"，" Command Line

Parameters"）


如何挂钩并查看该流程返回到

操作系统的代码是什么？如果您需要更多信息或准确的snipet代码，请

随时问。

I am running an application called AcroComm.exe to poll time clocks here at
our company. I have written a small C# app that will poll the clocks based
on information found in a DB. My problem is that AcroComm will sometimes
stop polling in the middle of the process and terminate. The programing
manual for the app says that it sends a code to the operating system when it
is done that tells what has happend like the following:

0 success
13 aborted
etc...

When it aborts the downloading, my program doesn''t know it, it just goes to
the next line of code and continues to poll the next clock. I am using code
like this: System.Diagnostics.Process.Start("AppPath\Name", "Command Line
Parameters")

How can I hook in and see what the code was that the process returned to the
operating system? If you need more info or an exact snipet of code, please
feel free to ask.

推荐答案

Anthony，


这里有两种选择。第一个是获取Process实例并且

调用WaitForExit方法。这将阻止当前线程，直到

进程完成。


第二个选项是注册退出事件（确保设置

进程上的EnableRaisingEvents为true。


无论你决定做什么，当这些事件发生时，你可以检查

的值使用ExitCode属性来查看返回给操作系统的内容。


希望这会有所帮助。

Anthony,

You have two options here. The first is to get the Process instance and
call the WaitForExit method. This will block the current thread until the
process has completed.

The second option is to register for the Exited event (make sure you set
EnableRaisingEvents on the process to true).

Whichever you decide to do, when these events occur, you can check the
value of the ExitCode property to see what was returned to the OS.

Hope this helps.

我还是C＃的新手...你能不能给我一个例子

或者指点我在正确的方向阅读它？

Tony，


而不是这样做：

System.Diagnostics.Process.Start （AppPath \ Name，命令行参数）;


执行此操作：


//创建流程。

using（Process process = Process.Start（" AppPath\Name"，" Command Line

Parameters"））

{

//等待过程完成。

process.WaitForExit（）;


//在此处访问ExitCode属性从你运行的

应用程序中获取退出代码。

}

Tony,

Instead of doing this:

System.Diagnostics.Process.Start("AppPath\Name", "Command Line Parameters");

Do this:

// Create the process.
using (Process process = Process.Start("AppPath\Name", "Command Line
Parameters"))
{
// Wait for the process to complete.
process.WaitForExit();

// Access the ExitCode property here to get the exit code from the
application you ran.
