Listing files in a directory

Posted by admin under ASP.NET 2.0

The following code snippet shows you how to list all files inside a certain folder in your web application:

 



            foreach(string sFile in 
                System.IO.Directory.GetFiles( Server.MapPath("images") ))
            {
                string sJustFile = new System.IO.FileInfo(sFile).Name;
		DoSomethingFunWithThis(sJustFile);

            }

The GetFiles demands an absolute path, but since your application might be running at a webhost where you have no idea if your site is located in c:\websites\yoursite or d:\hello\whatever\yoursite etc we use the Server.MapPath to let ASP.NET create the absolute path for us.  

You can also list files of just a certain type:



            foreach(string sFile in 
                System.IO.Directory.GetFiles( Server.MapPath("images"), "*.jpg" ))
            {
                string sJustFile = new System.IO.FileInfo(sFile).Name;
		DoSomethingFunWithThis(sJustFile);

            }

Now we will only receive the jpg files available in the images folder.
