WPF cmd.exe进程立即关闭

Question

在我的WPF应用程序中，我试图通过System.Diagnostics.Process打开cmd.exe，但每次遇到process.Start（）它立即关闭，我不能写任何其他内容。但是，如果我调用静态Process.Start（）它将保持打开但我不确定如何写入它。见下文。

        var processInfo = new ProcessStartInfo("cmd.exe")
        {
            UseShellExecute = false,
            RedirectStandardInput = true,
        };

        var process = new Process()
        {
           StartInfo = processInfo,
        };

        process.Start(); // This close immediately and not work 

        Process.Start("cmd.exe"); // This will work but can't write to it

        process.StandardInput.WriteLine(someText);
        process.StandardInput.WriteLine(moreText);

Answer 1

用于等待cmd。

process.WaitForExit(); 

Answer 2

我做了一些研究，发现实施的解决方案Here有效。不确定这是否是最佳方法，但它对我有用。

[DllImport("kernel32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool AllocConsole();

private void BtnSubmit_OnClick(object sender, RoutedEventArgs e)
    {
        var processInfo = new ProcessStartInfo("cmd.exe")
        {
            UseShellExecute = false,
            RedirectStandardInput = true
        };

        var process = new Process()
        {
            StartInfo = processInfo,
        };

        AllocConsole();
        process.Start(); // This close immediately and not work 

        process.StandardInput.WriteLine("someText");
        process.StandardInput.WriteLine("moreText");
        process.WaitForExit();
    }
