        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

using (SPSite oSiteCollection = new SPSite("https://localhost"))
{
    SPWebCollection collWebsites = oSiteCollection.AllWebs["MyWebSite"].Webs;

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

    foreach (SPWeb oWebsite in collWebsites)
    {
        SPFileCollection collFiles = oWebsite.GetFolder("Shared Documents").Files;

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

                try
                {
                    collFiles.Delete(strDelUrl);
