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).

Hidden fields are not displayed by the browser. A hidden field enables you to include data in a form that is not entered by the user. For example, you could use a hidden field to return a string that identifies a discussion thread.
