The HTML helper instance that this method extends.

The name of the form field and the ViewDataDictionary key that is used to look up the value.
- value

Return Value
Type: System.Web.Mvc.MvcHtmlString
An input element whose type attribute is set to "hidden".
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type HtmlHelper. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
Remarks
The difference between calling the Hidden method and using an input element is that the Hidden method is designed to make it easy to bind to view data or model data.
The htmlAttributes parameter consists of an object that contains name/value pairs. The attributes that are specified in the name/value pairs depend on the HTML element that is being rendered. For example, for an input element where type is set to "hidden", you might provide the following anonymous object:
new { id = "hidden1" }
New With { .id = "hidden1" }
