我真的 真正地 我不喜欢最后回答我自己的问题,尤其是当答案是基于一种达到结果的黑客方式时。

然而,我知道这可以节省其他人的时间。所以,我的解决方案是:

            try
            {
                WriteLine(commandId);

                createdProcesses = StartProcessAndCapture(commandId, process);

                process.BeginOutputReadLine();
            }
            catch (Exception exc)
            {
                WriteLine($"{commandId} : {exc}");
                throw;
            }

            return new CommandStartResult
            {
                MainProcess = process,
                CreatedProcesses = createdProcesses,
            };
        }

        private static Process PrepareProcess(

        )
        {
