Remarks

The RouteLink method renders an anchor (a) element that links to a URL, which could resolve to an action method, a file, a folder, or some other resource.

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 anchor (a) element, you might provide the following anonymous object:

new { target="_self", name="summary" }

New With {.target="_self", .name="summary" }
