Answer 1

我认为这可能是由于您的本地机器和服务器之间的Excel版本不同引起的。

Answer 2

This problem plagued me for quite a while. I had Excel 14.0 in the dev environment and Excel 15.0 in the production environment.

Here are a list of most things I tried to resolve the issue, however please keep in mind that it may have been one, all, or a combination of these things that resolved it for me.

1. Start -> Run -> lusrmgr.msc -> Add service account to Administrators group.

2. Component Services -> Computers -> My Computer -> Properties -> COM Security -> Add user to all permissions.

3. Component Services -> Computers -> My Computer -> DCOM Config -> Microsoft Excel Application -> Properties -> Security -> Add user to all permissions.

4. Component Services -> Computers -> My Computer -> DCOM Config -> Windows Management and Instrumentation -> Properties -> Security -> Add user to all permissions.

5. Excel -> File -> Options -> Trust Center -> Protected View -> Uncheck all 3 boxes.

6. Excel -> File -> Options -> Trust Center -> ActiveX Settings -> Enable all controls & uncheck safe mode.

7. Excel -> File -> Options -> Trust Center -> Macro Settings -> Enable all macros -> Trust access to the VBA project object model.

8. Excel -> File -> Options -> Trust Center -> File Block Settings -> Select Open selected file types in Protected View.

9. Excel -> File -> Options -> Trust Center -> File Block Settings -> Uncheck everything.

10. Excel -> File -> Options -> Trust Center -> External Content -> Enable all Data Connections; Enable automatic update for all Workbook links.

11. Excel -> File -> Options -> Trust Center -> Trusted Locations -> Check Allow Trusted Locations + Add C:\\ and any UNC paths + subdirectories.

12. Excel -> File -> Options -> Advanced -> Check "Ignore other applications that use Dynamic Data Exchange (DDE)"

13. In code, instead of using .SaveCopyAs, use .SaveAs with Excel.XlFileFormat.xlWorkbookDefault for xlsx files and Excel.XlFileFormat.xlOpenXMLWorkbookMacroEnabled for macro-enabled workbooks.
