Razor does not appear to have a "Button" HTML helper. You're likely finding references to a custom-built HTML helper extension.

There is no button helper as of mvc preview 3 (not mvc3) 

it was mentioned a bunch in the past for example:
<a href="http://blog.wekeroad.com/blog/aspnet-mvc-preview-using-the-mvc-ui-helpers/" rel="noreferrer">http://blog.wekeroad.com/blog/aspnet-mvc-preview-using-the-mvc-ui-helpers/</a>
however rolling your own is trivial - I have a basis for it somewhere around here I'll have to dig it up, but essentially just create a new Html.ButtonFor and copy the source code from Html.LabelFor and change the output to create an input type="button" tag.

To expand on the <a href="https://stackoverflow.com/a/5956495/1037948">accepted answer</a>, so you can bind a submit button to a model property but have different text:

<pre><code>@Html.ButtonFor(m =&gt; m.Action, Model.LabelForCurrentAction(), new { @class = "btn btn-primary btn-large", type = "submit" })
</code></pre>

Using the following <a href="https://stackoverflow.com/a/5956495/1037948">slightly modified <code>Button</code> helper class</a>:

MVC5 , Bootstrap ver 3.2.0

<pre class="lang-c# prettyprint-override"><code>@Html.ActionLink
(
 linkText: " Remove", 
 actionName: "Index", 
 routeValues: null, // or to pass some value -&gt; routeValues: new { id = 1 },
 htmlAttributes: new { @class = "btn btn-success btn-sm glyphicon glyphicon-remove" }
)
</code></pre>

This will generate a link that looks like a button.

this is weird. I see references out there for @Html.Button() but when I type that Intellisense doesn't find such a helper... there's dropdownlist, hidden, editors, et cetera, but no button!

what's up with that?

There's no @Html.Button !

这很奇怪。我看到了@Html.Button()的引用，但当我输入智能感知没有找到这样的助手时……有下拉列表，隐藏，编辑器，等等，但是没有按钮！这是怎么回事？
