C# 获取 cmd 输出，就像在真实 cmd 窗口中显示的一样

Question

我有一个 BackgroundWorker 线程，它运行一个 cmd 进程并向它写入多个命令。有些命令可能需要一段时间才能完成，所以我想向用户显示进度的 cmd 输出。 我运行 cmd 命令的代码如下所示:

private void backgroundWorker_DoWork(object sender, System.ComponentModel.DoWorkEventArgs e)
{
    var startInfo = new ProcessStartInfo("cmd.exe")
    {
        UseShellExecute = false,
        RedirectStandardInput = true,
        RedirectStandardOutput = true,
        CreateNoWindow = true
    };

    cmd = new Process { StartInfo = startInfo };

    cmd.OutputDataReceived += Cmd_OutputDataReceived;
    cmd.Start();
    cmd.BeginOutputReadLine();

    cmd.StandardInput.WriteLine($"cd {baseFolder}\\External Resources\\img files\\uboot");

    string[] commands = CmdCommands.GetUbootFlashCommands();
    foreach (var command in commands)
        cmd.StandardInput.WriteLine(command);

    cmd.StandardInput.WriteLine($"cd {baseFolder}\\External Resources\\img files\\android");
    commands = CmdCommands.GetKernelFlashCommands();
    foreach (var command in commands)
        cmd.StandardInput.WriteLine(command);

    cmd.StandardInput.WriteLine("exit");
    cmd.WaitForExit();
}

private void Cmd_OutputDataReceived(object sender, DataReceivedEventArgs e)
{
    Invoke(new Action(() =>
    {
        txtCmd.Text += e.Data + Environment.NewLine;
    }));
}

但是 cmd 输出与常规 cmd 窗口中显示的实际输出没有任何区别。 这是我的输出的样子:

Microsoft Windows [Version 10.0.14393]

C:\>cd C:\img files\uboot

C:\img files\uboot>fastboot flash XXX.bin

C:\img files\uboot>fastboot flash XXX.bin

C:\img files\uboot>cd C:\img files\android

C:\img files\android>fastboot flash kernel

C:\img files\android>fastboot flash system XXX.img

C:\img files\android>fastboot flash userdata XXX.img

C:\img files\android>fastboot flash cache XXX.img

C:\img files\android>exit

下面是当我打开 cmd 窗口并输入命令时输出的样子:

如何在我的 C# 代码中获得此输出？？？

Answer 1

你能试试这个简单的解决方案吗？我不知道在你的情况下它能成功多少。

        Process p = new Process();
        p.StartInfo.UseShellExecute = false;
        p.StartInfo.RedirectStandardOutput = true;
        p.StartInfo.FileName = "cmd.exe";
        p.StartInfo.Arguments = "/c ping 192.168.x.x"; //or your thing
        p.Start();


        string result = p.StandardOutput.ReadToEnd();
        p.WaitForExit();
