Dim siteCollection As New SPSite("http://MySiteCollection")

Try
    Dim delSites As SPWebCollection = siteCollection.AllWebs("MyWebSite").Webs

    Dim cutOffDate As DateTime = DateTime.UtcNow.AddDays(- 7)

    Dim delSite As SPWeb
    For Each delSite In  delSites
        Dim delFiles As SPFileCollection = delSite.GetFolder("Shared Documents").Files

        Dim i As Integer
        For i = delFiles.Count - 1 To (- 1) + -1 Step -1
            If delFiles(i).TimeLastModified < cutOffDate Then
                Dim delURL As String = delFiles(i).Url
                Try
                    delFiles.Delete(delURL)
                Catch Else
                End Try
            End If
        Next i
    Next delSite
Finally
    siteCollection.Dispose() 
End Try

using (SPSite oSiteCollection = new SPSite("https://localhost"))

    DateTime dtCutoffDate = DateTime.UtcNow.AddDays(-7);

    foreach (SPWeb oWebsite in collWebsites)

        for (int intIndex=collFiles.Count - 1; intIndex>-1; intIndex--)
