使用 c# 设置 mediaElement 的来源 [英] Using c# to set the source of a mediaElement

问题描述

我正在尝试使用 c# 编码设置媒体元素的来源(视频位于项目的资产文件夹中)，我的编码如下:

I am trying to set the source of a media element using c# coding (the video is located in the project's assets folder), my coding is as follow:

//Defined as such in my XAML
mediaElement.Source = new Uri(@"Assets\HarlemCampus.wmv");
mediaElement.Play();

...但是当我单击按钮播放视频时收到以下错误:

...but I am receiving the following error when I click the button to play the video:

我不想在 XAML 中预设源，因为我想根据用户在运行时选择的单选按钮动态更改媒体元素的源，是否有办法做到这一点?

I don't want to preset the source in XAML because I want to dynamically change the media element's source, according to the radiobutton selected by the user at runtime, if there's a way to do this?

推荐答案

你必须使用资源文件 Uri:

You'll have to use a resource file Uri:

mediaElement.Source = new Uri("ms-appx:///Assets/HarlemCampus.wmv");
