C#npoi Export 2007 version of Excel

Versions 2003 and 2007 differ:

Hssfworkbook (2003)

Iworkbook (Version 2007)

After writing, there will be a problem, the export will be error "stream is closed."

Npoi when you produce an. xlsx file, when you use Book.write (MS), the stream is closed, causing an error when you use the Respons output stream again.

I see some users to provide the solution is:

 Public classNpoimemorystream:memorystream {/// <summary>        ///gets whether the stream is closed/// </summary>         Public BOOLIscolse {Get; Private Set; }         PublicNpoimemorystream (BOOLColse=false) {Iscolse=Colse; }         Public Override voidClose () {if(iscolse) {Base.            Close (); }                    }    }

Use a custom stream instead of a memory stream to ensure that the stream is not self-closing
