Private Sub WorkbookUpdateLink()
    Dim Links As Array = _
        CType(Me.LinkSources(Excel.XlLink.xlExcelLinks),  _
        Array)
    If Links IsNot Nothing Then 
        Dim i As Integer 
        For i = 1 To Links.Length
            Me.UpdateLink(Links(i), _
                Excel.XlLinkType.xlLinkTypeExcelLinks)
        Next i
    Else
        MsgBox("The workbook contains no links to " & _
            "other workbooks.")
    End If 
End Sub

private void WorkbookUpdateLink()
{
    Array links = (Array)this.LinkSources(Excel.XlLink.xlExcelLinks);

    if (links != null)
    {
        for (int i = 1; i <= links.Length; i++)
        {
            this.UpdateLink((string)links.GetValue(i),
                Excel.XlLinkType.xlLinkTypeExcelLinks);
        }
    }
    else
    {
        MessageBox.Show("The workbook contains no links to " +
            "other workbooks.");
