C# - How To Retrieve The File Name Of A Class

Is there a method to retrieve the file name of a class?

Specifically I would like to create a static method (CreateLink) in a base class (BasePage) to automatically return the path and filename of the page called.

I code in .C# ASP.NET

private const string TEMPLATE = "~/One.aspx";
public static HyperLink CreateLink()
{
HyperLink link = new HyperLink();
link.Text = "Click here";
link.NavigateUrl = String.Format(TEMPLATE);
return link;
}

Is it possible to avoid the use of TEMPLATE hardcoded variable? Is it possible to retrieve the One.aspx path from file name and location?
