可能您遇到了与以下问题相同的问题:http://social.msdn.microsoft.com/Forums/en-CA/Vsexpressvb/thread/4565361b-aeff-4d01-af92-d21a6eb631e3 [ ^ ]
我发现了问题的原因，这是因为用户的本地设置与办公室版本不同，我使用了英语版本，并且在将语言设置为英语后，将国家/地区设置为美国(在区域和语言中)在控制面板下的设置可以正常工作

Probably you have the same problem as described at: http://social.msdn.microsoft.com/Forums/en-CA/Vsexpressvb/thread/4565361b-aeff-4d01-af92-d21a6eb631e3[^]
i found the cause of the problem, it''s because the user local settings are different from the office version, i use the english version and after setting language to english us, and country to united states in the reagional and language settings under control panel it worked fine

听起来像是您可能正在尝试使用旧版本的Visual Studio打开excel一样.可能是您拥有Visual Studio 2008和Microsoft Office2010.请尝试下载版本4框架，并引用2010 interopt dll.

注意:如果使用Microsoft.Office.Interop.Excel.Application的var insteaad，则将有助于提高可读性.

Sounds to me like you may be trying to open excel with a version of Visual Studio that is old. May be that you have Visual Studio 2008 and Microsoft Office 2010. Try to download the Version 4 framework, and reference the 2010 interopt dll.

Note: it would help readability if you used the var insteaad of Microsoft.Office.Interop.Excel.Application.
