How to get server path of VHD drive

Question

I want to get the server path of VHD drive. I am working on azure web application. I have some files uploaded and saved it in to the Test.VHD drive (say). This is a cloud drive inside some blob container "drives" (say). I mounted and mapped it by following way:

    driveLetter = drive.Mount(localCache.MaximumSizeInMegabytes - 20, DriveMountOptions.Force);

"driveLetter" is "A:\" (say). Now I am displaying all the pdf file names as link buttons on the page. On click of those files I want to open that pdf file in the browser by using the javascript function

    window.open(pdfPath, pdfName, 'scrollbars=yes, resizable=yes');

My question is what do I have to pass as a "pdfPath" parameter?

I have the path "A:\Uploads\<pdf name>.pdf". But I can't pass it. I have to pass it like http://servername:port/path so that user can view it.

But I don't know how to convert it to the link like http://servername:port/path. By doing this I can view the pdf in the browser.

Please help me,

Thanks in advance.

Hi,

You can't directly link to the file on the drive. You'll need to write code that servers the file in the HTTP response.

• You could use an HttpHandler to serve the file: http://dodgethecode.blogspot.com/2008/09/large-file-download-using-httphandler.html 
• If you work with ASP.NET MVC you could use the FileResult: http://dotnet.dzone.com/news/goodbye-http-handler-hello 

Hope this helps.
