How to get list of files from web URL outside my web application

I am using ASP.NET 4.5 with C#.

I have created a web API that points to the folders out of my web-application to get some shared resources. Now, I want to retrieve the list of files from the directory to which the web-api call points.

For example, my web application is resides on my local hard-drive's F:\Projects\Web1 directory. I have placed some images in C:\SharedRes\images directory. I have created a web-api that fetches images from this shared directory. For e.g. http://localhost/api/images/a.jpg will get the a.jpg from C:\SharedRes\images directory. It is working fine, but I want to get the list of files from C:\SharedRes\images whenever I make a call to web-api like http://localhost/api/images.

I have tried following : 

DirectoryInfo directoryInfo = new DirectoryInfo(HttpContext.Current.Server.MapPath("http://localhost/api/images"));
FileInfo[] file = directoryInfo.GetFiles().Where(f => f.Extension == (".bmp") || f.Extension == (".jpg") || f.Extension == (".png") || f.Extension == (".TIFF") || f.Extension == (".gif")).ToArray();

But it gives URI format not supported error.

Please let me know if any solution.

You Can simply use Directory class with it's GetFiles method to do so. The following code is for getting all files in C:\SharedRes\images\ directory:

string[] _Files = Directory.GetFiles(@"C:\SharedRes\images\");
if (_Files != null && _Files.Count() > 0)
{ 
  FileInfo _file;
  string   _fileName="";

  foreach (string file in _Files)
  {
       _file = new FileInfo(file);
       _fileName = _fileName + @"<br/>" + _file.Name;
  }

Response.Write(_fileName);

HttpServerUtility.MapPath method gets virtual path as parameter.

You should use HttpContext.Current.Server.MapPath("/api/images")
