I have a a private sub as follow:

1 Private Sub UnzipAndDeleteFiles()
2 Dim targetFolder As String = Server.MapPath(RadUpload1.TargetFolder)
3 Dim targetDir As New DirectoryInfo(targetFolder)
4 Dim targetExt As String
5
6 Dim strSourceFile As String = ""
7 Dim strDestFile As String = ""
8 Dim StrMessage As String = ""
9
10 Dim file As System.IO.FileInfo
11 For Each file In targetDir.GetFiles()
12 targetExt = Path.GetExtension(file.Name)
13 strSourceFile = targetFolder & "\" & file.Name
14 strDestFile = targetFolder & "\CMS\"
15 If targetExt.ToLower = ".zip" Then
16 StrMessage = StrMessage + FileSystemUtils.UnzipFile(strSourceFile, strDestFile, PortalSettings)
17 End If
18 If (file.Attributes And FileAttributes.ReadOnly) = 0 Then
19 file.Delete()
20 End If
21 Next file
22 End Sub


I keep getting an error: Object reference not set to an instance of an object. on Line # 16. I tried to debug and I noticed the Portalsettings disappears from the list of object in my debugging mode. I tried to store the portalsettings in a private object using "new" and still getting an error on the same line. Both parameters strSourceFile & strDestFile have values in them while debuging, and there is already a file that I'm trying to unzip in the folder. I used the same line as in the filemanager module. What I'm doing wrong?

I've got the same problem!

Anyone a solution?

My mistake, this in incorrect and has not solved the issue.

I ended up using the code on this page to un-zip file file.
