在C＃中运行Excel宏在特定工作簿中失败

Question

I'm trying to run a macro in an Excel workbook from C# using the standard Microsoft.Office.Interop.Excel library. In my scenario the version of Excel could be either 2010 or 2013.

There could be multiple workbooks open for the same Application object, each potentially with the same macro names, so I'm explicitly passing in the workbook name

string macro = string.Format("{0}!{1}", workbook.Name, macroName);
Application.Run(macro);

Weirdly, I get a COMException if the workbook name has hyphens in it:

Application.Run("My-Workbook!macro1")

But runs fine without hyphens:

Application.Run("MyWorkbook!macro1")

Is it just me or is this weird? Can anyone think of a workaround?

Answer 1

Wrap the workbook name in quotes

string macro = string.Format("'{0}'!{1}", workbook.Name, macroName);
Application.Run(macro);
