如何使用 C# 获取错误消息 [英] How to get the error message with C#

问题描述

对于vsinstr -coverage hello.exe，我可以使用C#代码如下.

For vsinstr -coverage hello.exe, I can use the C# code as follows.

Process p = new Process(); 
StringBuilder sb = new StringBuilder("/COVERAGE "); 
sb.Append("hello.exe"); 
p.StartInfo.FileName = "vsinstr.exe"; 
p.StartInfo.Arguments = sb.ToString(); 
p.Start(); 
p.WaitForExit();

出现错误时，我收到错误消息:Error VSP1018: VSInstr 不支持处理已检测的二进制文件..

When there's an error, I get the error message : Error VSP1018: VSInstr does not support processing binaries that are already instrumented..

如何使用 C# 获取此错误消息?

我可以从答案中得到错误信息.

I could get the error messages from the answers.

using System;
using System.Text;
using System.Diagnostics;

// You must add a reference to Microsoft.VisualStudio.Coverage.Monitor.dll

namespace LvFpga
{
    class Cov2xml
    {
        static void Main(string[] args)
        {
            Process p = new Process();
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.RedirectStandardError = true;         
            p.StartInfo.UseShellExecute = false; 

            StringBuilder sb = new StringBuilder("/COVERAGE ");
            sb.Append("helloclass.exe");
            p.StartInfo.FileName = "vsinstr.exe";
            p.StartInfo.Arguments = sb.ToString();
            p.Start();

            string stdoutx = p.StandardOutput.ReadToEnd();         
            string stderrx = p.StandardError.ReadToEnd();             
            p.WaitForExit();

            Console.WriteLine("Exit code : {0}", p.ExitCode);
            Console.WriteLine("Stdout : {0}", stdoutx);
            Console.WriteLine("Stderr : {0}", stderrx);
        }
    }
}

推荐答案

您需要重定向标准输出或标准错误.这是 stdout 的代码示例:

You need to redirect the standard output or standard error. Here's a code sample for stdout:

Process p = new Process();
p.StartInfo.FileName = "hello.exe";
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.UseShellExecute = false;
p.Start();
string stdout = p.StandardOutput.ReadToEnd(); 
p.WaitForExit();
