C# ASP.net, storing and writing HTML with string variables

Question

I have a form where users can enter a url to a YouTube video. My code parses the url and creates an embed string that is stored in my database. This looks something like:

string rawQuery = uri.Query;
int index = rawQuery.IndexOf("?");
if (index > 0)
                rawQuery = rawQuery.Substring(index).Remove(0, 1);
id = HttpUtility.ParseQueryString(rawQuery).Get("v");

string embedURL = "<iframe width=\"640\" height=\"360\" src=\"http://www.youtube.com/embed/" + id + "\" frameborder=\"0\" allowfullscreen></iframe>";

This string gets stored in the database and retrieved later and printed to an HTML page. However, the output ends up looking like this when I view the page source:

&lt;iframe width=&quot;640&quot; height=&quot;360&quot; src=&quot;http://www.youtube.com/embed/AXaoi6dz59A&quot; frameborder=&quot;0&quot; allowfullscreen&gt;&lt;/iframe&gt;

How can I print this string so that it doesn't escape my quotes and less/greater than symbols?

I think you should use @Html.Raw(string)

If you use, for example, ViewBag to output the string in the view use

@Html.Raw(ViewBag.EmbedURL)

This tell the framework to not encode the string

It's when you write the string in the page that it gets encoded. Use the <%= %> server tag to output the string without encoding it:

<%= embedURL %>

You can also wrap it in an HtmlString object to avoid the automatic encoding:

HtmlString html = new HtmlString(embedURL)

Then you can just output it as normal:

<%: html %>

or using razor:

@html

You can also use the Html.Raw method to wrap it in an HtmlString object:

@Html.Raw(embedURL)
