即使在进程退出后，Proc.WaitforExit（）调用是否也会阻塞线程

Question

我正在启动一个进程并异步读取标准输出和错误流，下面是这样做的代码。该api是否有可能阻塞线程或问题出在我代码的其他地方< / strong>，因为该线程仅在此api调用之前打印调试语句，但在此api调用之后不打印任何调试日志。因此，我怀疑该线程正在阻塞该线程或以其他方式杀死了该线程，因此不打印任何内容

请在这里帮助我

  public static string start_proc(string proc_name, string param, int timeout = 8000)

    private static void OutputHandler(StringBuilder data, object sendingProcess,

        if (!String.IsNullOrEmpty(outLine.Data))
        {
            data.Append(outLine.Data + Environment.NewLine);

        }
    }
