How do I open a file that is part of my solution?

Question

I have a document that I have included in my VS 2010 solution. It is in a folder called "MyFolder" the file itself is called "MyDoc.docx". I've tried the following ways to open the file but none work:

Stream s = File.OpenRead("/MyFolder/MyDoc.docx");

and

Stream s = File.OpenRead("MyFolder/MyDoc.docx");

and

Stream s = File.OpenRead("~/MyFolder/MyDoc.docx");

What is the proper path for this file?

Answer 1

using (var s = File.OpenRead(Server.MapPath("~/MyFolder/MyDoc.docx")))
{
    ...
}

where ~ indicates the site root. Also make sure you grant the account your site is running under read permissions to this folder.
