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 BeginForm method renders a form that will be handled by a controller action method.
You can use this method in a using block. In that case, the method renders the closing </form> tag at the end of the using block.
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 form element, you might provide the following anonymous object:
new { id = "text1", accept-charset="iso-8859-1" }
New With { .id = "text1", .accept-charset="iso-8859-1" }
