问题描述

我通常不是一个C#人,所以我希望这不是一个愚蠢的问题...



我有一个 .bat 文件(这当然是一个简化的例子):



file nn.bat >

  exit / B 3 


$ b b

当我从命令运行它时,看到%ERRORLEVEL%是3(太棒了!)



我有这个c#程式:



C#程式

 code> class Program 
{
static void Main(string [] args)
{
Process p = new Process();

p.StartInfo.FileName = @nn.bat;

p.Start();
p.WaitForExit();

int rc = p.ExitCode;

Console.WriteLine(rc);
}
}



我希望 rc <



我的错误在哪里?

最后,我找到了一个解决方法:



在我的批处理文件中,而不是使用 exit / B 3 我使用 exit 3



(和解释)来自答案



我仍然可以不能解释它如何为其他人使用 / B 选项 - 我的猜测是它必须做一些与他们的操作系统版本。


I'm usually not a C# person, so I hope it's not a stupid question...

I have a .bat file that looks like this (this is of course a simplified example):

file nn.bat

exit /B 3

When I run it from command I see that %ERRORLEVEL% is 3 (great!!)

I have this c# program:

C# Program

class Program
{
    static void Main(string[] args)
    {
        Process p = new Process();

        p.StartInfo.FileName = @"nn.bat";

        p.Start();
        p.WaitForExit();

        int rc = p.ExitCode;

        Console.WriteLine(rc);
    }
}

I expect rc to be 3, but it's always 0 no matter what I try ...

Where is my mistake ?

解决方案

Finally, I've found a workaround:

In my batch file, instead of using exit /B 3 I used exit 3.

The idea (and explanation) came from this answer

I still can't explain how it worked for others with the /B option - my guess is that it has to do something with their operating system version.
