显示/隐藏C控制台应用程序的控制台窗口

去应用程序的 然后改变主意 输出类型 从 控制台应用程序 Windows应用程序

方法如下:

using System.Runtime.InteropServices;

[DllImport("kernel32.dll")]
static extern IntPtr GetConsoleWindow();

[DllImport("user32.dll")]
static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

const int SW_HIDE = 0;
const int SW_SHOW = 5;

var handle = GetConsoleWindow();

// Hide
ShowWindow(handle, SW_HIDE);

// Show
ShowWindow(handle, SW_SHOW);

我建议将项目输出类型设置为 而不是控制台应用程序。它不会显示控制台窗口,而是像控制台应用程序那样执行所有操作。

您可以执行相反的操作,并将应用程序输出类型设置为:Windows Application。然后将此代码添加到应用程序的开头。

[DllImport("kernel32.dll", EntryPoint = "GetStdHandle", SetLastError = true, CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
public static extern IntPtr GetStdHandle(int nStdHandle);

[DllImport("kernel32.dll", EntryPoint = "AllocConsole", SetLastError = true, CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
public static extern int AllocConsole();

private const int STD_OUTPUT_HANDLE = -11;
private const int MY_CODE_PAGE = 437;
private static bool showConsole = true; //Or false if you don't want to see the console

static void Main(string[] args)
{
    if (showConsole)
    {
        AllocConsole();
        IntPtr stdHandle = GetStdHandle(STD_OUTPUT_HANDLE);
        Microsoft.Win32.SafeHandles.SafeFileHandle safeFileHandle = new Microsoft.Win32.SafeHandles.SafeFileHandle(stdHandle, true);
        FileStream fileStream = new FileStream(safeFileHandle, FileAccess.Write);
        System.Text.Encoding encoding = System.Text.Encoding.GetEncoding(MY_CODE_PAGE);
        StreamWriter standardOutput = new StreamWriter(fileStream, encoding);
        standardOutput.AutoFlush = true;
        Console.SetOut(standardOutput);
    }

    //Your application code
}

showConsole 是 true

请看我的帖子:

Show Console in Windows Application

“只是为了隐藏”你可以:

将输出类型更改为 控制台应用程序 到 Windows应用程序

而不是 Console.Readline/key 你可以用 new ManualResetEvent(false).WaitOne() 以保持应用程序运行。

如果不想依赖窗口标题,请使用以下选项:

    [DllImport("user32.dll")]
    static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

    IntPtr h = Process.GetCurrentProcess().MainWindowHandle;
    ShowWindow(h, 0);
    Application.EnableVisualStyles();
    Application.SetCompatibleTextRenderingDefault(false);
    Application.Run(new FormPrincipale());

如果集成一个小批量应用程序没有问题,那么有一个叫做 Cmdow.exe 这将允许您根据控制台标题隐藏控制台窗口。

Console.Title = "MyConsole";
System.Diagnostics.Process HideConsole = new System.Diagnostics.Process();
HideConsole.StartInfo.UseShellExecute = false;
HideConsole.StartInfo.Arguments = "MyConsole /hid";
HideConsole.StartInfo.FileName = "cmdow.exe";
HideConsole.Start();

HideConsole.StartInfo.Arguments = "MyConsole /Vis";
