	[OptionalAttribute] Object Type



One of the XlLink values specifying the type of links to return.

Return Value

An Array of link names in the workbook; a null reference (Nothing in Visual Basic) if the workbook does not contain any links of the specified Type.

The names in the returned Array are the names of the linked documents, editions, or DDE or OLE servers. The format of the array is a one-dimensional array for all types but publisher and subscriber. The returned strings contain the name of the link source, in the appropriate notation for the link type. For example, DDE links use the "Server|Document!Item" syntax.

For publisher and subscriber links, the returned array is two-dimensional. The first column of the array contains the names of the edition, and the second column contains the references of the editions as text.

Optional Parameters

private void WorkbookLinkSources()
    Globals.Sheet1.Range["A1", missing].Value2 =
    Array links = (Array)this.LinkSources(Excel.XlLink.xlExcelLinks);

    for (int i = 1; i <= links.Length; i++)
        this.OpenLinks((string)links.GetValue(i), true,
