全屏使用示例：
FormScreen.ShowFullScreen( "你的窗体"）;

隐藏任务栏:
FormScreen.ShowHHTaskBar();

显示任务栏:
FormScreen.HideHHTaskBar();

设备的屏幕宽度:
FormScreen.Width;

设备的屏幕高度:

FormScreen.Height

public class FormScreen
    { 
        const uint SHFS_SHOWTASKBAR = 0x0001; 
        const uint SHFS_HIDETASKBAR = 0x0002; 
        const uint SHFS_SHOWSIPBUTTON = 0x0004; 
        const uint SHFS_HIDESIPBUTTON = 0x0008; 
        const uint SHFS_SHOWSTARTICON = 0x0010; 
        const uint SHFS_HIDESTARTICON = 0x0020; 
        const int SW_HIDE = 0; 
        const int SW_SHOWNORMAL = 1; 
        const int SW_SHOWMINIMIZED = 2;

        const int SW_RESTORE = 9; 
        const int SW_SHOWDEFAULT = 10;
