asp.net load file class library

Question

I'm working on asp.net (vb, maybe that can change something)

I have a project using as class library. I want it to load a text file. the file is on a folder on this project

usely I use "File.Exists" and "Server.MapPath("~")". but I do not have Server lib.

I look a way to use the file as content or resource. but I didnt succed for the moment(probably my fault)

So if you know a way to do what I want? Or how to use the file as a resource like by stream or something else?

I looked at this but my first try not working (http://keithelder.net/2007/12/14/How-To-Load-an-Embedded-Resource-From-A-DLL/)

I will have little problem, because my framework didn't copy my text file to iis. — forX

Add System.Web as a project reference to your class library, and use HttpContext:

using System.Web;

public class Foo
{
    public void Bar()
    {
        var path = HttpContext.Current.Server.MapPath("~/somefolder/somefile.txt");
    }
}

It can or it can't be used? Assuming you meant that it can't be used, why?

HttpContext.Current.Server.MapPath("~") is the of root my site, but MapPath("..."); cause an error

The ellipses ("...") was intended to be a placeholder for the path to the file. I updated my answer so it's a little more clear.
