file.Exists function not working

 Dim f1 As New FileInfo(Server.MapPath("/CaseStudyImages/TemporaryImages/"))
            Dim f2 As New FileInfo(Server.MapPath("/CaseStudyImages/" & success & "/"))
            Dim dir1 As DirectoryInfo = f1.Directory
            Dim dir2 As DirectoryInfo = f2.Directory
             Dim Folder1Files As FileInfo() = dir1.GetFiles()
            If Folder1Files.Length > 0 Then
                For Each aFile As FileInfo In Folder1Files
                    If File.Exists("f1" & aFile.Name) Then
                        File.Delete("f2" & aFile.Name)
                    End If
                    aFile.MoveTo("f2" & aFile.Name)
                Next
        End If

In this line its showing errror, File.Exists("f1" & aFile.Name) Then

System.UnauthorizedAccessException: Access to the path is denied. 

i think tprb is with exists function

Which part of "Access to the path is denied" you do not understand? File.Exists function requires read permissions on the path that's being checked, you need to sort out permissions.

sorry u were wrong 

we have to pass string in exist function 

here is the working code

 Dim filepathName As String = HttpContext.Current.Server.MapPath("/CaseStudyImages/" & success & "/")
            Dim filepathName2 As String = HttpContext.Current.Server.MapPath("/CaseStudyImages/TemporaryImages/")

            Dim dir1 As New DirectoryInfo(filepathName2)
            Dim dir2 As New DirectoryInfo(filepathName)
            Dim Folder1Files As FileInfo() = dir1.GetFiles()
            If Folder1Files.Length > 0 Then
                For Each aFile As FileInfo In Folder1Files
                    aFile.MoveTo(filepathName & aFile.Name)
                    If File.Exists(filepathName & aFile.Name) Then
                        File.Delete(filepathName2 & aFile.Name)
                    End If
                Next
            End If
