如何捕获外部程序的错误消息文本 [英] How do catch the text of error messages of external program

问题描述

我正在使用System.Diagnostics Process运行外部程序。如果出现错误，程序会使用消息框报告此问题，如何捕获错误消息的文本？一些例子？

I'm running an external program using System.Diagnostics Process. In case of errors the program reports this with a messagebox, How can I catch the text of error messages? Some example ?

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
static class Program
    {
   static void Main()
        {
              System.Diagnostics.Process proc = new System.Diagnostics.Process(); 
            proc.StartInfo.FileName = "C:/Program Files (x86)/1Cv77/BIN/1cv7s.exe"; 
            proc.StartInfo.Arguments = "enterprise /D D:/1C_Bases/ANRBase_60 /Nemail /Pemail";
            proc.EnableRaisingEvents = true;
            proc.Start();
            proc.WaitForExit();
        }
    }
}

推荐答案

一般来说，运行任何外部设备都不是最佳选择程序。它意味着单独的过程;并且流程很好地隔离（在单独的地址空间中执行等）如果某个流程不是为某些协作而设计的，那么尝试从中获取任何内容都非常非生产。



但是，某些应用程序可能适合此类协作。这一切都取决于你可以假设的行为。它可以是使用标准控制台的过程，也可以是其他应用程序重定向其输出（以及更少见的输入）的方式。如果是这种情况，您应该使用 System.Diagnostic.Process 重定向 StandardOutput 和 StandardError 。该过程可以在这些流中的任何一个中输出错误信息;你需要检查一下。请参阅：

http://msdn.microsoft.com /en-us/library/vstudio/system.diagnostics.process [ ^ ]，

http://msdn.microsoft.com/en-us/library/vstudio/system.diagnostics.process.standarderror [ ^ ]，

http://msdn.microsoft.com/en-us/library/vstudio/system.diagnostics.process .standardoutput [ ^ ]。



您可以在上面引用的最后一个MSDN页面上找到一个很好的代码示例。

Generally, it's not a best idea to run any external program at all. It means the separate process; and the processes are well isolated (executed in separate address spaces, etc.) If a process is not designed for some collaboration, trying to get anything from it is highly non-productive.

However, some applications can be suited for such collaboration. It all depends what behavior you can assume. It can be a process using standard console the way it can be used by other applications redirecting its output (and, more rarely, input). If this is the case, you should use System.Diagnostic.Process redirecting StandardOutput and StandardError. The process may output error information in either of those streams; you will need to check it up. Please see:
http://msdn.microsoft.com/en-us/library/vstudio/system.diagnostics.process[^],
http://msdn.microsoft.com/en-us/library/vstudio/system.diagnostics.process.standarderror[^],
http://msdn.microsoft.com/en-us/library/vstudio/system.diagnostics.process.standardoutput[^].

You will find a good code sample on the last MSDN page referenced above.

我想你必须尝试显示InnerException消息

i think you have to try to display the InnerException Message

try
         {
//Do something 
         }
         catch (Exception e)
         {
          console.writeLine(   e.InnerException.Message )

 

         }
