Number of files in a folder

Question

How to get the number of files from a folder using ASP.NET using C #?

Answer 1

System.IO.Directory myDir = GetMyDirectoryForTheExample(); int count = myDir.GetFiles().Length; 

Answer 2

You can use the Directory.GetFiles method

Also see Directory.GetFiles method (String, String, SearchOption)

You can specify a search option in this overload.

TopDirectoryOnly : includes only the current directory in the search.

AllDirectories . Includes the current directory and all subdirectories in the search operation. This option includes reprocessing points, such as installed drives and search symlinks.

 // searches the current directory and sub directory int fCount = Directory.GetFiles(path, "*", SearchOption.AllDirectories).Length; // searches the current directory int fCount = Directory.GetFiles(path, "*", SearchOption.TopDirectoryOnly).Length; 

Answer 3

The weakest method is to use LINQ :

 var fileCount = (from file in Directory.EnumerateFiles(@"H:\iPod_Control\Music", "*.mp3", SearchOption.AllDirectories) select file).Count(); 

Answer 4

 System.IO.DirectoryInfo dir = new System.IO.DirectoryInfo("SourcePath"); int count = dir.GetFiles().Length; 

You can use this.

Answer 5

Reading PDF files from a directory:

To get the number of specific type extensions using LINQ , you can use this simple code:

 Dim exts() As String = {".docx", ".ppt", ".pdf"} Dim query = (From f As FileInfo In directory.GetFiles()).Where(Function(f) exts.Contains(f.Extension.ToLower())) Response.Write(query.Count())
