Recently I encountered a problem when dealing with export word document that needs to be replaced when export data rows either use "\ r \ n" or "^ p" so a variety of ways online, said no solution, "\ n" in here are just a playing out of space, and later found the solution:

xwpfRun.AddBreak(BreakType.TEXTWRAPPING)

xwpfRun.AddBreak(BreakClear.ALL)

 
       /// <summary>

       xwpfRun.AddBreak(BreakType.TEXTWRAPPING); 
       //换行 
      
       xwpfRun.SetText(fillContent); 
      
       xwpfRun.FontSize = fontSize; 
       //字体大小 
      
       xwpfRun.IsBold = isBold; 
       //是否加粗 
      
       xwpfRun.SetFontFamily( 
       "宋体" 
       , FontCharRange.None); 
       //设置字体（如：微软雅黑,华文楷体,宋体） 
      
       xwpfRun.SetTextPosition(rowsHeight);

       return  
       paragraph; 
      
       }

Achieve results:

Note: This wrap is to change the position of text. So AddBreak () needs to be placed SetText thereby achieving the above effect before ().

I saw someone say xwpfRun.AddCarriageReturn () This can also wrap, but after trying the effect is only space, but also tried to use (char) 11 content wrap, but guided by the word open, being only two more Effective methods;

If you want to specify a new line of cell contents, here we need to put this method to add a parameter to change it
