问题描述
Does anyone know the syntax for this? I've been looking everywhere and all I can find is C++ code for this. I'm trying to password protect an excel file programatically using the System.IO.Packaging namespace.
Any ideas?
Additional notes:
I'm NOT using the Excel interop--but instead the System.IO.Packaging namespace to encrypt and password protect the excel file.
解决方案
If you want an Excel password all you need is something like this:
using Microsoft.Office.Interop.Excel
//create your spreadsheet here...
WorkbookObject.Password = password;
WorkbookObject.SaveAs("spreadsheet.xls")
This requires Excel to be installed.
That's nothing to do with System.IO.Packaging of course, so you might need to restate your question...
