BUT !! Position is not a dependency property, so you

问题 I am writing a media player and I'm using WPF in C#. My problem is that I have no idea of how to create a fade in/ fade out function (using the media element), meaning that the last 7 seconds of the playing song will start to fade out and at the same time the first 7 seconds of the next song will start to play. Has anyone done this? If so, then can someone please help me? Thank you. 回答1: You could put a trigger on MediaElement.Position that starts a DoubleAnimation on MediaElement.Volume when

问题 I have this MediaElement in my xaml page: <MediaElement x:Name="soundMenu" Source="Sounds/menu.wav" AutoPlay="False" MediaEnded="soundMenu_MediaEnded"/> and I want it to play when page is loaded (like background music): void MainPage_Loaded(object sender, RoutedEventArgs e) { soundMenu.Play() } It doesn't work. When I click on some button and try to play music it's working but this isn't. What's wrong with this? How can I play sound after page is loaded? P.s.: I know I must check if user is

问题 I need to run a background music in WP7 Silverlight application. I need it to keep playing when navigating between pages. Also I don't want it to stop when another sound effect is played. 回答1: You can use a MediaElement to do that or use XNA SoundEffects but I have a better solution. Create a SilverXNA project for your app. You don't really need to use XNA but this project automatically creates some stuff which makes life easier. You can use this to build a Silverlight App with no problems.

问题 On my windows phone app, I want to play a short .wav audio, similar to windows when it boots up. At first I tried using an event handler when one of my controls was loaded (this worked about 60% of the time, which is very interesting, maybe someone can clear that up as well, I'm thinking it has to do with the order things happen to load. That's why its different each time running it). I'm using visual studios 2012 ultimate, this is my xaml code for the .wav file: <MediaElement x:Name="MySound

问题 I'm trying to use the MediaElement control in WPF to play back video. It works great in Vista, but when I run it on an XP machine I get tearing in the display. It looks as if it's not using the vertical synch, and just updating the screen mid-draw. Anyone know how to fix this problem? 回答1: This has more to do with the way WPF renders to the screen under XP compared to Vista. Under Vista, apps render to an offscreen buffer which is then composited with other windows that have changed and is

问题 I am trying to use MediaTimeline and DoubleAnimation inside Storyboard to play audio with animation. Everything is implemented in C# without XAML. Nothing happens after Storyboard.Begin is called in the code below and no exception is thrown. mediaElement's HasAudio property is false and MediaOpened event of MediaElement is never called. It seems mediaElement can't load the audio file. I don't know whether MediaElement or MediaTimeline is responsible for loading the audio. DoubleAnimation

问题 i have a single video (duration: 3 seconds) and i need to create 2 states 1- the video should always reach the second 1.5 and play it from the start. TimeSpan ts = new TimeSpan(0, 0, 0, 1, 500); TimeSpan ts_Start = new TimeSpan(0, 0, 0, 0, 0); if (mediaElement.position == ts) mediaElement.position = ts_Start; //doesnt work this block code 2- when i press a button, the video should play the full video (3 seconds).

问题 I have converted a video to bytes array and stored it in MsSql Database. Now I fetch it from database and I get the byte array. I want to set this byte array as Source of media element and then show this video in WPF application. Please suggest a way where I can convert byte array or memory stream to Media Elements Source? I will not have permission to write on users machine, so writing a file onto user machine and then setting the source will not work for me. 回答1: That's not directly
