public ReadOnlyDocumentProperties LoadDocumentProperties(
    byte[] buffer
)

buffer	Byte[]	A byte array that contains document data.

Returns

Type	Description
ReadOnlyDocumentProperties	An object that stores the retrieved document properties.

Remarks

Use this method to load document metadata (document properties) without loading the workbook itself. You can use the retrieved metadata to search for a specific document, to organize files, or to collect statistics.

The Spreadsheet Document API can load document properties from workbooks in the following formats:

• XLSX,

• XLSM,

• XLSB,

• XLS,

• XLTX,

• XLTM,

• XLT,

• XML (XML Spreadsheet 2003).

For CSV and TXT files or encrypted documents, the LoadDocumentProperties method returns empty properties. If the loaded document is corrupted or its format is unknown, the LoadDocumentProperties method throws an exception.
