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 b8020aae-374d-46a9-bcb7-8cc2390b93b6 or 175ce3ff-9bbf-4e64-8421-faeb81a0bb51.


Exception Condition

The name parameter is nulla null reference (Nothing in Visual Basic) or empty.


The ListBox method renders an element that enables the user to select from a scrolling list of items. Each item in the list is a SelectListItem object.

The difference between calling the ListBox method and using a select element is that the ListBox 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 a select element, you might provide the following anonymous object:

new { id = "select1", size="8" }
New With { .id = "select1",.size="8" }
