Set Mediaelement Source to Relative URI in WPF Code

问题

I have a project that is WPF4 and VB.net. I'm trying to set a mediaelement's source using a mediatimeline (inside a storyboard construct), so I can loop the mediaelement. However, I cannot figure out how to set the source to a relative URI in WPF. I know how to do it in VB.net, but by setting the source there, I can't have the media looping.

How do I set the source of a mediaelement in a mediatimeline to a relative URI?

回答1:

See the MSDN reference to the MediaElement.Source property. Make sure the media file property "Copy To Output" is set to "Copy Always" or "Copy If Newer".

Example:

<MediaElement x:Name="xyzName" Width="Auto" Height="Auto" Source="MediaFolder/YourMediaFile.mov" />
