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.");

}
