The HtmlHelper class generates HTML elements. For example, @Html. ActionLink("Create New", "Create") would generate anchor tag <a href="/Student/Create">Create New</a> . There are many extension methods for HtmlHelper class, which creates different HTML controls.
What is HTML Helper in ASP.NET MVC 5? HTML Helpers are methods that return a string. Helper class can create HTML controls programmatically. HTML Helpers are used in View to render HTML content. It is not mandatory to use HTML Helper classes for building an ASP.NET MVC application.
@addTagHelper makes Tag Helpers available The code above uses the wildcard syntax ("*") to specify that all Tag Helpers in the specified assembly (Microsoft. AspNetCore. Mvc. TagHelpers) will be available to every view file in the Views directory or subdirectory.
Tag Helpers are attached to HTML elements inside your Razor views and can help you write markup that is both cleaner and easier to read than the traditional HTML Helpers. HTML Helpers, on the other hand, are invoked as methods that are mixed with HTML inside your Razor views.
In order to create an anonymous type (or any type) with a property that has a reserved keyword as its name in C#, you can prepend the property name with an at sign, @:
Html.BeginForm("Foo", "Bar", FormMethod.Post, new { @class = "myclass"})
For VB.NET this syntax would be accomplished using the dot, ., which in that language is default syntax for all anonymous types:
Html.BeginForm("Foo", "Bar", FormMethod.Post, new with { .class = "myclass" })
Current best practice in CSS development is to create more general selectors with modifiers that can be applied as widely as possible throughout the web site. I would try to avoid defining separate styles for individual page elements.
If the purpose of the CSS class on the <form/> element is to control the style of elements within the form, you could add the class attribute the existing <fieldset/> element which encapsulates any form by default in web pages generated by ASP.NET MVC. A CSS class on the form is rarely necessary.
