以 Windows 形式启动 psexec 进程失败

Question

因此，我创建了一个表单，允许我们的营销团队重新启动计算机，为访客显示幻灯片/重要信息等

计划是将其部署到其他用户计算机，然后他们可以执行以下三项任务之一： 立即重启 定时/计划重启 取消定时/计划重启

该应用程序在我的计算机上运行良好，在调试和构建中都很好。 在其他人的计算机上安装时，它似乎正在启动 psexec 但随后什么也没做。

我添加了一些 catch 异常，此时它显示了以下错误：

标准没有被重定向

但是，在对此进行研究时，我似乎已经拥有大多数人建议解决此问题的代码。

我的代码如下：

            Stop_Restart.WaitForExit();
        }


    }




      }
}

我在尝试捕获错误时添加了以下更改，但这并没有帮助我进一步了解。 我将在此处仅添加一个用于显示的控件，但它已应用于每个按钮

private void Btn_stop_restart_Click(object sender, EventArgs e)
    {
        try
        {
            Process Stop_Restart = new Process();
            Stop_Restart.StartInfo.UseShellExecute = false;
            Stop_Restart.StartInfo.RedirectStandardOutput = true;
            Stop_Restart.StartInfo.RedirectStandardError = true;
            Stop_Restart.StartInfo.RedirectStandardInput = true;
            Stop_Restart.StartInfo.FileName = Programmability.psexecpath;
            var cancel_args = new List<string> { Programmability.mediawallcomputername, Programmability.addadminuseraccount, Programmability.addadminpassword, "shutdown -a" };
            Stop_Restart.StartInfo.Arguments = String.Join(" ", cancel_args);
            using (var stopreader = Stop_Restart.StandardOutput)
            {
                Stop_Restart.BeginOutputReadLine();
                Stop_Restart.Start();
                string Output = Stop_Restart.StandardOutput.ReadToEnd();
                string Errormessage = Stop_Restart.StandardError.ReadToEnd();
                Stop_Restart.WaitForExit();
                var StopConsoleOut = stopreader.ReadToEnd();
                MessageBox.Show(StopConsoleOut, "Success", MessageBoxButtons.OK);
            }
        }
        catch (Exception)
        {
            MessageBox.Show($"Running psexec failed as {Programmability.psexecpath}", "Error", MessageBoxButtons.OK);
            throw;
        }
    }

Answer 1

我将根据您的“它在我的机器上工作”和“PSExec 正在打开但没有做任何事情”的信息来回答。

请记住，当第一次运行 PSExec 时，您需要根据 PSExec 的输出使用 -accepteula：

“这是该程序的第一次运行。您必须接受 EULA 才能继续。使用 -accepteula 接受 EULA。”

您是否在要部署此表单应用程序的计算机上完成了此步骤？

编辑：

如果您已接受 EULA，那么您应该尝试确定 var "Errormessage" 是什么。

我会 - 为了在您部署的机器上进行故障排除 - 建议您执行类似的操作

Restart_now.Start();
string Output = Restart_now.StandardOutput.ReadToEnd();
string Errormessage = Restart_now.StandardError.ReadToEnd();
MessageBox.Show(Errormessage);
Restart_now.WaitForExit();

这样您就可以看到您要部署此应用程序的设备上发生了什么故障（如果有）。 您可能会发现由于多种原因（无法连接到远程 PC、权限不足等），他们的机器上没有运行 PSExec 命令
