控制台——禁用关闭按钮

控制台中禁止使用右上角的关闭按钮，下面是核心代码

[DllImport("user32.dll", EntryPoint = "FindWindow")]
extern static IntPtr FindWindow(string lpClassName, string lpWindowName);
[DllImport("user32.dll", EntryPoint = "GetSystemMenu")]
extern static IntPtr GetSystemMenu(IntPtr hWnd, IntPtr bRevert);
[DllImport("user32.dll", EntryPoint = "RemoveMenu")]
extern static IntPtr RemoveMenu(IntPtr hMenu, uint uPosition, uint uFlags);
/// <summary>
/// 禁用关闭按钮
/// </summary>
static void closebtn()
{
    IntPtr windowHandle = FindWindow(null, "test");
    IntPtr closeMenu = GetSystemMenu(windowHandle, IntPtr.Zero);
    uint SC_CLOSE = 0xF060;//系统菜单命令Id
    RemoveMenu(closeMenu, SC_CLOSE, 0x0);
}

控制台主函数入口调用方法

protected static void CloseConsole(object sender, ConsoleCancelEventArgs e)
{
    Environment.Exit(0);//提供给操作系统的退出代码。使用 0（零）指示处理已成功完成
}
static void Main(string[] args)
{
    Console.Title = "test";
    closebtn();
    Console.CancelKeyPress += new ConsoleCancelEventHandler(CloseConsole);
    Console.WriteLine("Starting...");
    Console.WriteLine("退出请按 Ctrl+C ");
    Console.Read();
}

参考：RemoveMenu、Win32API中的GetSystemMenu和系统菜单命令Id
