问题描述
我正在 .NET MVC4 中编写一个 Web 应用程序，并且想使用 Markdown.我知道有一些开源 C# Markdown 库，但我还没有找到一个明显支持在 Markdown 文本中嵌入 youtube 或 Vimeo 视频的库.
I'm writing a web app in .NET MVC4 and would like to use Markdown. I understand there are a few open source C# Markdown libraries, but I haven't found one that obviously supports embedding youtube or Vimeo videos inside Markdown text.
有人知道这是否可能吗?
Does anyone know if it's possible?
推荐答案
The Solution using Standard Markdown ( not iFrame! )
使用 iframe 不是明显"的解决方案...尤其如果 Markdown 解析器 (或发布平台)您使用的不支持内联来自其他网站的内容......相反，您可以通过在 Markdown 中包含有效链接图像来伪造"文件，使用以下格式:
The Solution using Standard Markdown ( not iFrame! )
Using an iframe is not the "obvious" solution... especially if the Markdown parser (or publishing platform) you are using does not support inlining content from a different website ... Instead you can "fake it" by including a valid linked-image in your Markdown file, using this format:
[](http://www.youtube.com/watch?v=YOUTUBE_VIDEO_ID_HERE"视频标题")
如果这个 Markdown 代码片段看起来很复杂，请将其分解为两部分:
If this markdown snippet looks complicated, break it down into two parts:
一张图片
包裹在链接中[链接文字](http//example.io/my-link "链接标题")
我们从 YouTube 直接获取缩略图图像并链接到实际视频，因此当人们点击图像/缩略图时，他们将被带到视频中.
We are sourcing the thumbnail image directly from YouTube and linking to the actual video, so when the person clicks the image/thumbnail they will be taken to the video.

OR如果您想给读者一个视觉提示，即图像/缩略图实际上是一个可播放视频，在 YouTube 中拍摄您自己的视频截图，并将其用作缩略图.
OR If you want to give readers a visual cue that the image/thumbnail is actually a playable video, take your own screenshot of the video in YouTube and use that as the thumbnail instead.

虽然这需要几个额外的步骤 (a) 截取视频的屏幕截图和 (b) 上传它 因此您可以将图像用作缩略图，它确实具有3 个明显优势:
While this requires a couple of extra steps (a) taking the screenshot of the video and (b) uploading it so you can use the image as your thumbnail it does have 3 clear advantages:
- 阅读您的 Markdown(或生成的 html 页面)的人有一个视觉提示告诉他们他们可以观看视频(视频控件鼓励点击)
- 您可以选择视频中的特定帧用作缩略图(从而使您的内容更具吸引力)
- 您可以链接到视频中的特定时间，点击链接的图像时将从该时间开始播放.(在我们的例子中是 35 秒)
- The person reading your markdown (or resulting html page) has a visual cue telling them they can watch the video (video controls encourage clicking)
- You can chose a specific frame in the video to use as the thumbnail (thus making your content more engaging)
- You can link to a specific time in the video from which play will start when the linked-image is clicked. (in our case from 35 seconds)
截取屏幕截图需要几秒钟时间，每个操作系统都有键盘快捷键，可以将屏幕截图复制到剪贴板，这意味着您可以粘贴以加快上传速度.
Taking a screenshot takes a few seconds and there are keyboard shortcuts for each OS which copy the screenshot to your clipboard which means you can paste it for even faster upload.
而且由于这是100% 标准降价，它适用于任何地方(不仅适用于C#code> 解析器！) ...在 GitHub、Reedit 或 Ghost 上试用！
And since this is 100% Standard markdown, it works everywhere (not just for the C# parser!) ... try it on GitHub, Redit or Ghost!
这种方法也适用于 Vimeo 视频
This approach also works with Vimeo videos
