Examples

The following code example copies each of the files in a document library of a Web site to a document library in another Web site. The example preserves the time created and last modified values of the original library.

Try
    Dim srcSiteCollection As New SPSite("http://SourceSiteCollection")

    Try
        Dim srcWebSite As SPWeb = srcSiteCollection.AllWebs("SourceWebSite")
        Dim srcList As SPList = srcWebSite.GetList("SourceWebSite/SourceDocLib")

        Dim srcItems As SPListItemCollection = srcList.Items

        Dim srcItem As SPListItem
        For Each srcItem In  srcItems
            Dim srcFile As SPFile = srcItem.File
            Dim srcStream As Stream = srcFile.OpenBinaryStream()

            Dim destinSiteCollection As New SPSite("http://DestinationSiteCollection")

            Try
                Dim destinWebSite As SPWeb = destinSiteCollection.OpenWeb("DestinationWebSite")
                Dim destinList As SPList = destinWebSite.GetList("DestinationWebSite/DestinationDocLib")

                Dim destinFiles As SPFileCollection = destinList.RootFolder.Files

                Try
                    Dim destinFile As SPFile = destinFiles.Add(destinList + "/" + srcFile.Name, srcStream, srcFile.Author, srcFile.ModifiedBy, srcFile.TimeCreated, srcFile.TimeLastModified)

                    Dim destinItem As SPListItem = destinFile.Item

Note

Certain objects implement the IDisposable interface, and you must avoid retaining these objects in memory after they are no longer needed. For information about good coding practices, see Disposing Objects.
