移动

storyboard.Begin(); 

//注册界面刷新事件Loaded

CompositionTarget.Rendering +=newEventHandler(Timer_Tick);      //匀速

rivatevoID Timer_Tick(object sender,EventArgs e) {            }

 

//定义线程   循环

 dispatcherTimer dispatcherTimer =newdispatcherTimer(dispatcherPriority.normal);

 dispatcherTimer.Tick +=newEventHandler(Timer_Tick);

 dispatcherTimer.Interval =TimeSpan.FromMilliseconds(50);//重复间隔

图片截取

image.soruce=new BitmAPImage(new Uri(@"Player\" + count + ".png",UriKind.relative));private BitmapSource cutimage(string imgaddress,int x,int y,int wIDth,int height) {      return new CroppedBitmap(                BitmapFrame.Create(new Uri(imgaddress,UriKind.relative)),new Int32Rect(x,y,wIDth,height)                );}

 

循环给二维数组赋值

privatebyte[,] Matrix = newbyte[1024,1024];

for (int y = 0; y < Matrix.GetUpperBound(1); y++) {

                for (int x = 0; x < Matrix.GetUpperBound(0); x++) {

                    Matrix[x,y] = 1;

                }

  }

 

SL光标

public static Cursor[] GameCursors = new Cursor[4];

        ///<summary>

        ///返回指定标号光标

        ///</summary>

        ///<param name="sign">标号</param>

        ///<returns>光标</returns>

        public static Cursor getCursor(int sign) {

            if (GameCursors[sign] == null) {

                GameCursors[sign] = new Cursor(new fileStream(string.Format(@"Cursors\{0}.ani",sign),fileMode.Open,fileAccess.Read,fileShare.Read));

            }

            return GameCursors[sign];

        }
