wix - 如何在 WiX 中读取自定义操作的可执行输出？

Question

我正在 WiX 中制作 MSI 安装程序。在安装期间，我想从 custom action 运行可执行文件并获取其标准输出(不是返回码)以供以后在安装过程中使用(据说带有 Property 元素)。

如何在 WiX (3.5) 中实现它？

我将此代码用于类似的任务(它是一个 C# DTF 自定义操作):

// your process data
ProcessStartInfo processInfo = new ProcessStartInfo() {
   CreateNoWindow = true,
   LoadUserProfile = true,
   UseShellExecute = false,
   RedirectStandardOutput = true,
   StandardOutputEncoding = Encoding.UTF8,
   ...
};

Process process = new Process();
process.StartInfo = processInfo;
process.OutputDataReceived += (object sender, DataReceivedEventArgs e) =>
  {
     if (!string.IsNullOrEmpty(e.Data) && session != null)
     {
         // HERE GOES THE TRICK!
         Record record = new Record(1);
         record.SetString(1, e.Data);
         session.Message(InstallMessage.ActionData, record);
      }
  };

process.Start();
process.BeginOutputReadLine();
process.WaitForExit();

if (process.ExitCode != 0) {
   throw new Exception("Execution failed (" + processInfo.FileName + " " + processInfo.Arguments + "). Code: " + process.ExitCode);
}

process.Close();
