How to find files in a folder in an ASP.NET application using C#?

Question

I have created an Asp.net application.

It contains a folder called PDF and a folder called Requirement just beneath that.

I have a link in another page called Requirement.

If i click on that link i need to find all the files in the folder PDF/Requirement.

You can google for this and get your answer in under 1 minute. — Sergey Akopov, Apr 07 '12 at 15:22
I get only string "/pdf/Requirement". I need to append application path along with above. How can i do that ? — Pradeep, Apr 07 '12 at 15:27
I tried Request.ApplicationPath. But return only root application Folder name, not all path where that folder exists ? — Pradeep, Apr 07 '12 at 15:29
You can use Server.MapPath("~/pdf/requirement") to get the full path. Tilda char means get the path relative to the application root (which might not coincide with the website's root, since in a website you can have other applications) — Adrian Iftode, Apr 07 '12 at 17:04
In the future, please breakup your questions into sub-questions, recursively as needed, so that you eventually end up with *specific*, *concrete* problems. As-is, you've clarified that you really had several problems. — Kenny Evitt, May 15 '14 at 16:41

var getFileName = Directory.GetFiles(Server.MapPath("~/PDF/Requirement"));  // Collection Of file name with extention.

var getFileNameExcludeSomeExtension1 = from f in Directory.GetFiles(Server.MapPath("~/PDF/Requirement"))
                                       where Path.GetExtension(f) != ".scc" && Path.GetExtension(f) != ".db"
                                       select Path.GetFileNameWithoutExtension(f);   // Collection Of file name with extention and filtering.

var getFileNameExcludeSomeExtension2 = from f in Directory.GetFiles(Server.MapPath("~/PDF/Requirement"))
                                       where Path.GetExtension(f) != ".scc" && Path.GetExtension(f) != ".db"
                                       select Path.GetFileName(f);   // Collection Of file name with out extention and filtering.

I suggest to use EnumerateFiles as this Regex to find a file in folder and if you tried GetFiles dont because of performance you could see difference in this What is the difference between Directory.EnumerateFiles vs Directory.GetFiles?
