Writing/outputting HTML strings unescaped

asp.net-mvc asp.net-mvc-3 razor

I've got safe/sanitized HTML saved in a DB table.

How can I have this HTML content written out in a Razor view?

It always escapes characters like < and ampersands to &.

To save people the long history of discussion below - @Html.Raw()

To save people like me trying to do this with with anonymous types in dynamically typed views, where this won't work - see this answer to my more-specific question. Although using this approach with a strongly-typed view is still better if your situation allows.

Supposing your content is inside a string named mystring...

You can use:

@Html.Raw(mystring)

Alternatively you can convert your string to HtmlString or any other type that implements IHtmlString in model or directly inline and use regular @:

@{ var myHtmlString = new HtmlString(mystring);}
@myHtmlString

Thanks for this answer. Helped me finish a little task I was learning. :) However I'm using the latest version of MVC3 and so far no Html.Raw :(

Hi Sergio. I'm using MVC 3 and i'm using the Raw method properly.

Thank you for the answer! I'm still learning MVC 3 and this was eluding me.

@Lorenzo, +1 I'm using the latest MVC 3 with razor syntax and Html.Raw is definitely available to me.

Lorenzo, I've updated answer to remove mentioning of MVC Beta as it was some years ago. Feel free to revert/change.

In ASP.NET MVC 3 You should do something like this:

// Say you have a bit of HTML like this in your controller:
ViewBag.Stuff = "<li>Menu</li>"
//  Then you can do this in your view:
@MvcHtmlString.Create(ViewBag.Stuff)

I prefer this method because HTML.Raw blows up if the passed string is null.

Thanks, this is very clean!

You can use

@{ WriteLiteral("html string"); }

This was awesome for me, was using Razor within a Hangfire app to send emails... Html.Raw() doesn't work there

1 for WriteLiteral

Sometimes it can be tricky to use raw html. Mostly because of XSS vulnerability. If that is a concern, but you still want to use raw html, you can encode the scary parts.

@Html.Raw("(<b>" + Html.Encode("<script>console.log('insert')</script>" + "Hello") + "</b>)")

Results in

(<b>&lt;script&gt;console.log('insert')&lt;/script&gt;Hello</b>)

You can put your string into viewdata in controller like this :

 ViewData["string"] = DBstring;

And then call that viewdata in view like this :

@Html.Raw(ViewData["string"].ToString())

Apart from using @MvcHtmlString.Create(ViewBag.Stuff) as suggested by Dommer, I suggest you to also use AntiXSS library as suggested phill http://haacked.com/archive/2010/04/06/using-antixss-as-the-default-encoder-for-asp-net.aspx

It encodes almost all the possible XSS attack string.

Complete example for using template functions in RazorEngine (for email generation, for example):

@model SomeModel
@{
    Func<PropertyChangeInfo, object> PropInfo =
        @<tr class="property">
            <td>
                @item.PropertyName                
            </td>
            <td class="value">
                <small class="old">@item.OldValue</small>
                <small class="new">@item.CurrentValue</small>                
            </td>
        </tr>;
}

<body>

@{ WriteLiteral(PropInfo(new PropertyChangeInfo("p1", @Model.Id, 2)).ToString()); }

</body>
