Hello,

How to set page orientation landscape and portrait in same word document using NPOI C#

I am using this code but this code is not running with NPOI in c#.

XWPFDocument doc=new XWPFDocument();
CT_Document document=doc.getDocument(); // getDocument() not showing in NPOI with c#
Please help me.

I am using NPOI Library for create word document.
Note: I am not using Apache.POI, and we can't use Apache.POI.

Thanks in Advance.

What I have tried:

private void changeOrientation(XWPFDocument document, String orientation){
    CTDocument1 doc = document.getDocument();
    CTBody body = doc.addNewBody();
    body.addNewSectPr();
    CTSectPr section = body.getSectPr();
    if(!section.isSetPgSz()) {
        section.addNewPgSz();
    }
    CTPageSz pageSize = section.getPgSz();
    if(orientation.equals("landscape")){
        pageSize.setOrient(STPageOrientation.LANDSCAPE);
        pageSize.setW(BigInteger.valueOf(842 * 20));
        pageSize.setH(BigInteger.valueOf(595 * 20));
    }
    else{
        pageSize.setOrient(STPageOrientation.PORTRAIT);
        pageSize.setH(BigInteger.valueOf(842 * 20));
        pageSize.setW(BigInteger.valueOf(595 * 20));
    }
}
