Workbook.LinkSources Method

Returns an Array of links in the workbook.

Namespace: Microsoft.Office.Tools.Excel
Assembly: Microsoft.Office.Tools.Excel (in microsoft.office.tools.excel.dll)

public virtual Object LinkSources (
	[OptionalAttribute] Object Type
)

Parameters

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

For information on optional parameters, see Understanding Optional Parameters in COM Interop.

The following code example adds an external Excel link to the current workbook and gets an array of the names of all Excel links in the workbook by using the LinkSources method. The example then uses the OpenLinks method to open each linked workbook as read-only.

private void WorkbookLinkSources()
{
    Globals.Sheet1.Range["A1", missing].Value2 =
        @"='C:\[Book2.xls]Sheet1'!R2C2";
    Array links = (Array)this.LinkSources(Excel.XlLink.xlExcelLinks);

    for (int i = 1; i <= links.Length; i++)
    {
        this.OpenLinks((string)links.GetValue(i), true,
            Excel.XlLink.xlExcelLinks);
    }
}
