How to specify a file path in ASP.NET MVC

Question

I want to specify a virtual path of a file but I am not able to do so.

Here is my code:

int Course_Id = 1;
int PortfolioID=1;
int ChandidateID=1;

string filepath = Server.MapPath("~/ePortfolio/PortFolioContent/" + Course_Id + "/Assignments/Exhb_" + item.PortfolioID + "_" + item.ChandidateID + ".jpg");

if(System.IO.File.Exists((filepath)))
{                            
    ViewBag.Thumbnail = filepath;
}

When i use Server.MapPath it is fetching data from some other path:
My original path is:
E:\HOBBYHOMES(E-PORTFOLIO)\HobbyHomesWebApp\ePortfolio\PortFolioContent\1\Assignments
but it is taking this path
E:\HOBBYHOMES(E-PORTFOLIO)\HobbyHomesWebApp\ActivityPostin\Images\ePortfolio\PortFolioContent\1\Assignments\Exhb_1_1.jpg
I m not understanding why this is workin so.Please help me

I don't have a good solution for you, but here is why what you've tried so far doesn't work. I don't think ~ expands to anything in filepaths on Windows--some command shells do that but not the filesystem itself. '..' is going to be based on the current working directory (which is likely the directory of the executable you are running, or something equally useless). — SirPentor

Try string filepath = Server.MapPath("~/... ...jpg");

You can use @Url.Content("~/Content/Images/YourImageName.png")

Your are going for the following path string filepath = Server.MapPath("~/ePortfolio/e-Portfolio/PortFolioContent/" + Course_Id + "/Assignments/Exhb_" + PortfolioID + "_" + ChandidateID + ".jpg"); 1) E:\HOBBYHOMES(E-PORTFOLIO)\HobbyHomesWebApp\ePortfolio\PortFolioContent\1\Assignments 2) E:\HOBBYHOMES(E-PORTFOLIO)\HobbyHomesWebApp\ActivityPostin\Images\ePortfolio\PortFolioContent\1\Assignments\Exhb_1_1.jpg I can not see folder e-Portfolio. Can you please update your question again and what exact path you want?As per me you want 2nd path and getting first path.

Try doing something like this:

Path.Combine(Server.MapPath("~/"),("ePortfolio\\PortFolioContent\\" + Course_Id + "\\Assignments\\Exhb_" + item.PortfolioID + "_" + item.ChandidateID + ".jpg"));

In theory it results in the same answer that failed you previously. In practice, it may yield a completely different answer.

There's also a recent question here (which I can't find at the moment) which highlights that sometimes Server.MapPath("~/..etc..") misbehaves on rewritten request paths. Are you rewriting the request that is trying to form this path?
