MediaElement Object Introduction

It is easy to use MediaElement to build the ability to play video files in the application face.

For example:

The MediaElement control is declared in XAML code, and the Source property value is set to the URI of the video.

<mediaelement x:name= "Media" source= "video/azure_tmobile_500k.wmv" width= "the/>"

In C # code, declare the MediaElement control as follows:

MediaElement MediaElement = new MediaElement ();   
       
Mediaelement.name = "MediaElement1";   
       
Mediaelement.width = n;   
       
Mediaelement.source = new Uri ("ms-appx:///video/azure_tmobile_500k.wmv");   
       
THIS.GRID1.CHILDREN.ADD (mediaElement);

The allowed effect diagram is as follows:

When the page is loaded, the MediaElement is played automatically. In general, to prevent the video from playing automatically, set the MediaElement control's AutoPlay property value to False.
