How do I read a file located in a same folder where my page resides in in ASP.NET?

Question

How do I read a file located in a same folder where my page resides in in ASP.NET (C#)? I have a page called mypage.aspx and I'm trying to read in a file called foo.txt residing in a same directory as this page.

Is there a way to open that file for reading with File.OpenRead()? Providing a relative path like File.OpenRead("foo.txt") fails b/c of the location of the file.

Answer 1

It should be something like

File.OpenRead(Server.MapPath("foo.txt"));

Answer 2

You should try File.OpenRead(Server.MapPath("foo.txt")).

If MapPath doesn't expand/can't find the proper path at this point then try it while specifying the relative path to the page in question starting from the sites virtual root (using the tilde (~) at the beginning of the string to indicate this), i.e. File.OpenRead(Server.MapPath("~/path/foo.txt"))
