asp.net - Creating a URL in the controller .NET MVC

Question

I need to be able to construct a link in the Action on the controller to send an email. What is best practice to do this? I don't want to construct it myself in case my routes change.

Should I have a view for each email and render that and send it? That might be a good way of doing it.

If you just want to get the path to a certain action, use UrlHelper:

UrlHelper u = new UrlHelper(this.ControllerContext.RequestContext);
string url = u.Action("About", "Home", null);

if you want to create a hyperlink:

string link = HtmlHelper.GenerateLink(this.ControllerContext.RequestContext, System.Web.Routing.RouteTable.Routes, "My link", "Root", "About", "Home", null, null);

Intellisense will give you the meaning of each of the parameters.

Update from comments: controller already has a UrlHelper:

string url = this.Url.Action("About", "Home", null);
