ellipse1.Fill =new SolidColorBrush( Colors.Black) 颜色填充

图片加载Uri uri = new Uri("img/1.jpg", UriKind.RelativeOrAbsolute);BitmapImage img = new BitmapImage(uri);

直接创建xaml  using System.Text;using System.Windows.Markup;StringBuilder sb = new StringBuilder();sb.Append("<Textblock>");sb.Append("xmlns=/"http://schemas.microsoft.com/client/2007/"");sb.Append("Canvas.Left........../>");TextBlock tb = new TextBlock();tb = (TextBlock)XamlReader.Load(sb.ToString());

线程问题newthread = new Thread(new ThreadStart(mm));newthread.Start();

 void mm()        {            int i = 60;            while (i > 0)            {                tb1.Dispatcher.BeginInvoke(delegate() { tb1.Text = i.ToString(); });                if (i == 0)                {                    newthread.Abort();                    newthread.Join();                    return;                }                i--;                                Thread.Sleep(1000);

            }

        }

定时器 DispatcherTimer timer = new DispatcherTimer();            //设置间隔1秒            timer.Interval = new TimeSpan(0, 0, 1);            //创建事件处理            timer.Tick += new EventHandler(timer_Tick);            //开始计时            timer.Start();void timer_Tick(object sender, EventArgs e)        {            //输出时间            tb1.Text = "当前时间:" + DateTime.Now.ToLongTimeString();        }

全屏模式using System.Windows.Interop; Content obj = Application.Current.Host.Content;  obj.IsFullScreen = true;

 FrameworkElement s = sender as FrameworkElement; s.ReleaseMouseCapture();停址鼠标 s.CaptureMouse(); 捕捉鼠标

控件外边界button1.Margin = new Thickness(4);

文件操作using System.IO.IsolatedStorage; spath = "tablea.txt";            spath = System.IO.Path.Combine(spath);void savefile(string savepath, string content)        {            IsolatedStorageFile storefile = IsolatedStorageFile.GetUserStoreForApplication();            IsolatedStorageFileStream sf = storefile.CreateFile(savepath);            using (StreamWriter sw = new StreamWriter(sf))            {                sw.WriteLine(content);            }            sf.Close();                    }        void loadfile(string readpath)        {            string content = string.Empty;            using (IsolatedStorageFile storefile = IsolatedStorageFile.GetUserStoreForApplication())            {                if (storefile.FileExists(readpath))                {                    StreamReader sr = new StreamReader(storefile.OpenFile(readpath, FileMode.Open, FileAccess.Read));                    content = sr.ReadToEnd();                }            }        }        void deletefile(string path)        {            using (IsolatedStorageFile storefile = IsolatedStorageFile.GetUserStoreForApplication())            {                storefile.DeleteFile(path);            }        }
