C# 全屏实现
就和虚拟机一样的，全屏显示的时候只显示视图区域内容，当鼠标移动到某一位置时出现浮动菜单，可以退出全屏或者其他操作！

把窗体模式设置为没有标题栏的那种 然后最大化出来的就是全屏了

C# codethis.FormBorderStyle= FormBorderStyle.None;this.WindowState= FormWindowState.Maximized;

你说的这样吧，菜单、状态栏工具栏什么的都在的
我想要的是虚拟机的那效果或者播放器全屏时的那效果！

[解决办法]
C# codethis.FormBorderStyle= FormBorderStyle.None;this.WindowState= FormWindowState.Maximized;

[解决办法]
老外的一个全屏，使用方法：
FormState formState = new FormState();
this.SetVisibleCore(false);
formState.Maximize(this);
this.SetVisibleCore(true);

C# code

using System;using System.Drawing;using System.Windows.Forms;using System.Runtime.InteropServices;namespace LC_Game{    /// <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 = true;                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;        }    }}

据说Visual C#初学者工具包中有个屏保程序
屏保程序肯定是要全屏的，楼主不妨参考下

单是无边框窗体最大化是无法实现的，
隐藏控件还要把桌面的任务栏给隐藏吧
------解决方案-------------------- 
 
已经隐藏了任务栏了，和改变刷新率一起用，就能达到类似游戏全屏的效果。
[解决办法]
锁屏吧？样式先设成NONE,然后获取当前系统分辨率，按分辨率来设置长、宽，再设置成ISTOP，就OK了。别说不成，魔兽都是这样弄的，只不过是把电脑分辨率设置为窗体长宽。
[解决办法]
this.FormBorderStyle = FormBorderStyle.None;
           this.WindowState = FormWindowState.Maximized;

[解决办法]
把窗体的TopMost属性设置为True,然后根据你要显示的区域计算窗体的Top和Left属性的值。细节的部分要怎么处理我就不说了先。
