Server.MapPath() Equivalant In Console App?

I am trying to get get the path of a directory that I have a template file in. ie in asp.net I use

Dim path as string = Server.MapPath("~/Reports/")) and then once I have the Reports dir I can do this
Using r As StreamReader = New StreamReader(path & "Template.htm")
Dim line As String

[code]...

That works great in asp.net but now I need to do the same thing in a console app. I have tried the function path = GetFullPath("~/Reports/") and instead of getting the absolute path to the Reports dir it returns /bin/debug/reports which is wrong. The file Template.htm is not in that directory.
