如何隐藏任务栏并让程序使用可用空间

Question

我想要隐藏任务栏并打开任何程序，使用任务栏所在的新空间。我试着用这个班。 使用系统; 使用System.Runtime.InteropServices;

public class Taskbar
{
    [DllImport("user32.dll")]
    private static extern int FindWindow(string className, string windowText);

    [DllImport("user32.dll")]
    private static extern int ShowWindow(int hwnd, int command);

    [DllImport("user32.dll")]
    public static extern int FindWindowEx(int parentHandle, int childAfter, string className, int windowTitle);

    [DllImport("user32.dll")]
    private static extern int GetDesktopWindow();

    private const int SW_HIDE = 0;
    private const int SW_SHOW = 1;

    protected static int Handle
    {
        get
        {
            return FindWindow("Shell_TrayWnd", "");
        }
    }

    protected static int HandleOfStartButton
    {
        get
        {
            int handleOfDesktop = GetDesktopWindow();
            int handleOfStartButton = FindWindowEx(handleOfDesktop, 0, "button", 0);
            return handleOfStartButton;
        }
    }

    private Taskbar()
    {
        // hide ctor
    }

    public static void Show()
    {
        ShowWindow(Handle, SW_SHOW);
        ShowWindow(HandleOfStartButton, SW_SHOW);
    }

    public static void Hide()
    {
        ShowWindow(Handle, SW_HIDE);
        ShowWindow(HandleOfStartButton, SW_HIDE);
    }
}

然后我调用Taskbar.Hide()，但是程序没有使用新空间。
