分配控制台的WinForm应用程序 [英] Allocate a console for a WinForm application

问题描述

我用下面的代码来分配控制台的WinForm应用程序。控制台窗口显示成功和输出是存在的。但是，当我关闭控制台窗口，我的WinForm的广告应用程式是在同一时间关闭。为什么？我想保持在WinForm的窗口。

I use the following code to allocate a Console for a WinForm application. The Console window shows up successfully and the output is there. But when I close the Console window, my WinForm applicaion is closed at the same time. Why? I want to keep the WinForm window.

private void btn_to_console_Click(object sender, EventArgs e)
{
    if (NativeMethods.AllocConsole())
    {
        lbl_console_alloc_result.Text = "Console allocation successfully!";
        IntPtr stdHandle = NativeMethods.GetStdHandle(NativeMethods.STD_OUTPUT_HANDLE);
        Console.WriteLine("from WinForm to Console!");
        lbl_console_alloc_result.Text = Console.ReadLine();
    }
    else
        lbl_console_alloc_result.Text = "Console allocation failed!";
}

[System.Runtime.InteropServices.DllImportAttribute("kernel32.dll", EntryPoint = "GetStdHandle")]
public static extern System.IntPtr GetStdHandle(Int32 nStdHandle);

/// Return Type: BOOL->int
[System.Runtime.InteropServices.DllImportAttribute("kernel32.dll", EntryPoint = "AllocConsole")]
[return: System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.Bool)]
public static extern bool AllocConsole();

谢谢...

Thanks in advance...

推荐答案

关闭控制台窗口将关闭任何应用程序 - 无论是一个控制台应用程序，Windows窗体，原生的Windows应用程序，或WPF应用程序。这是控制台窗口一个功能。

Closing a Console Window will shutdown any application -whether a console application, Windows Forms, native Windows app, or WPF application. This is a "feature" of Console windows.

如果你不希望这种行为，你应该，相反，只是做一个自定义窗口，以显示你的输出，而不是使用一个控制台窗口。否则，你需要调用 FreeConsole ，而不是关闭窗口分离你的应用程序的控制台窗口。

If you don't want this behavior, you should, instead, just make a custom window to display your output instead of using a Console Window. Otherwise, you need to call FreeConsole instead of closing the Window to detach your application from the Console window.
