c# - 在启动任务栏上覆盖全屏 C# 应用程序

Question

我使用 visual studio 编写了一个 Kiosk 风格的 C# 应用程序，它在启动时运行并且应该扩展到全屏并覆盖任务栏。

我正在执行通常的设置边界样式为无，并填充范围，如果我只是手动启动应用程序，它会完美地工作。

当应用程序在启动时启动(通过开始菜单中启动文件夹中的快捷方式)，任务栏最终位于程序顶部并且单击窗体上的某处不会返回窗体到顶部。

有没有人以前遇到过这个问题，或者知道可能的解决方法。

我之前也这样做过:

public class Screensize
{
    /// <summary>
    /// Selected Win AI Function Calls
    /// </summary>

    public class WinApi
    {
        [DllImport("user32.dll", EntryPoint = "GetSystemMetrics")]
        public static extern int GetSystemMetrics(int which);

        [DllImport("user32.dll")]
        public static extern void
            SetWindowPos(IntPtr hwnd, IntPtr hwndInsertAfter,
                         int X, int Y, int width, int height, uint flags);

        private const int SM_CXSCREEN = 0;
        private const int SM_CYSCREEN = 1;
        private static IntPtr HWND_TOP = IntPtr.Zero;
        private const int SWP_SHOWWINDOW = 64; // 0x0040

        public static int ScreenX
        {
            get { return GetSystemMetrics(SM_CXSCREEN); }
        }

        public static int ScreenY
        {
            get { return GetSystemMetrics(SM_CYSCREEN); }
        }

        public static void SetWinFullScreen(IntPtr hwnd)
        {
            SetWindowPos(hwnd, HWND_TOP, 0, 0, ScreenX, ScreenY, SWP_SHOWWINDOW);
        }
    }

    /// <summary>
    /// Class used to preserve / restore state of the form
    /// </summary>
    public class FormState
    {
        private FormWindowState winState;
        private FormBorderStyle brdStyle;
        private bool topMost;
        private Rectangle bounds;

        private bool IsMaximized = false;

        public void Maximize(Form targetForm)
        {
            if (!IsMaximized)
            {
                IsMaximized = true;
                Save(targetForm);
                targetForm.WindowState = FormWindowState.Maximized;
                targetForm.FormBorderStyle = FormBorderStyle.None;
                targetForm.TopMost = false;
                WinApi.SetWinFullScreen(targetForm.Handle);
            }
        }

        public void Save(Form targetForm)
        {
            winState = targetForm.WindowState;
            brdStyle = targetForm.FormBorderStyle;
            topMost = targetForm.TopMost;
            bounds = targetForm.Bounds;
        }

        public void Restore(Form targetForm)
        {
            targetForm.WindowState = winState;
            targetForm.FormBorderStyle = brdStyle;
            targetForm.TopMost = topMost;
            targetForm.Bounds = bounds;
            IsMaximized = false;
        }
    }

只需调用您的表单:

screensize.Maximize(this)

我想你是这个意思
