WinForms and Xna ,使用外部Form的完美解决方案

继承 Microsoft.Xna.Framework.Game,

graphics设置参数时,更改为传入的句柄

通过this.Window.Handle获取内置FORM对象，将其设置TOP，确定不出现在显示器中，即可。

内置FORM的VisibleChanged事件订阅：当显示内置FORM时，将其设置设置成不可见！！！

public class WinGame : Microsoft.Xna.Framework.Game    {        GraphicsDeviceManager graphics;        public WinGame()        {            graphics = new GraphicsDeviceManager(this);            drawHandle = IntPtr.Zero;        }        IntPtr drawHandle;        Form form;        public WinGame(Form form)            : this(form,form.Handle)        {        }        public WinGame(Form form, IntPtr drawHandle)            : this()        {            this.form = form;            this.drawHandle = drawHandle;            graphics.PreparingDeviceSettings += (s, e) =>            {                if (drawHandle == IntPtr.Zero) return;                e.GraphicsDeviceInformation.PresentationParameters.DeviceWindowHandle = this.drawHandle;                Mouse.WindowHandle = this.DeviceDrawControl.FindForm().Handle; //mouse状态支持            };            if (drawHandle == IntPtr.Zero) return;            Form gameWindowForm = Control.FromHandle(this.Window.Handle) as Form;            gameWindowForm.FormBorderStyle = FormBorderStyle.None;            gameWindowForm.Top = -2000 + gameWindowForm.Height * -1;            gameWindowForm.VisibleChanged += (s, e) =>            {                if (!gameWindowForm.Visible) return;                gameWindowForm.Visible = !gameWindowForm.Visible;            };        }        protected override void BeginRun()        {            if (this.form != null)            {                this.form.FormClosing += (s, e) =>                {                    base.Exit();                };            }            base.BeginRun();        }        public void SetBackColor(Color color)        {            if (this.drawHandle == IntPtr.Zero) return;            var control = Control.FromHandle(this.drawHandle);            control.BackColor = System.Drawing.Color.FromArgb(color.R, color.G, color.B);        }    }

XNA项目中，所有继承自Microsoft.Xna.Framework.Game，全部改成从WinGame继承！

修改入口函数

static void Main(string[] args)        {            //using (Game1 game = new Game1())            //{            //    game.Run();            //}            using (Form1 form = new Form1())            {                using (Game1 game = new Game1(form, form.GetPtr()))                {                                        form.Show();                    game.Run();                }            }            System.Windows.Forms.Application.Exit();        }

form.GetPtr()方法，可以返回form自己的句柄，也可以是子控件的句柄！

这样不需要使用老外的那个事例中实现的XNA控件，又可以使用GAME的对象进行开发，方便！
