C # use Npoi to read and write the 2007 version of Excel's Detour

C # uses Npoi to read and write classes online a lot, not repeat here.

I quote the Dll:npoi.dll,npoi.ooxml.dll,npoi.openxml4net.dll,

The same code that operates version 2003 of Excel does not have a problem, when you operate version 2007 of Excel, there is an inexplicable problem, and the catch is not the exception information.

WORKAROUND: You need to refer to ICSharpCode.SharpZipLib.dll.

So there are four DLLs that need to be referenced: Npoi.dll,npoi.ooxml.dll,npoi.openxml4net.dll,icsharpcode.sharpziplib.dll (this DLL is required for version office2007).
