10/20/2009Count the Number of files in a Directory using asp.net

Count the Number of specified files in a Directory

Below is a function 'FilesDirectoryCount' that will count the number of files within a directory using The .NET Framework class Directory. The GetFiles method allows us to retrieve all the files with a '.jpg' file extension and we can then use the Length property to return the number of files.



Get Sample Code
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Dim FileCount As Integer = FilesDirectoryCount("C:\Inetpub\wwwroot\website1\images", ".gif")
If FileCount = 0 Then
lblFilesInDirectory.Text = "There are no gif files in the directory."
ElseIf FileCount = 1 Then
lblFilesInDirectory.Text = "There is 1 gif files in the directory." Else
lblFilesInDirectory.Text = "There are " & FilesDirectoryCount("H:\Inetpub\wwwroot\website1\images", "*.gif") & " gif files in the directory."
End If
End Sub



Function FilesDirectoryCount(ByVal myDirectory As String, ByVal Extension As String) As Integer
Return Directory.GetFiles(myDirectory, "*" & Extension).Length
End Function

Step 4. In the opening window, uncheck "Allow Anonymous access" and check "Integrated Windows Authentication" (allowing anonymous can make that you don't have enough permissions to debug) After that you also need to make sure your NT Debugger user is on Debugger users group (and in practise to attach to the aspnet_wp.exe process it also needs to be admin unless you change local security policies.
