1. First import npoi DLL, this online has a lot of self-download. Go to the official website: http://npoi.codeplex.com/The download requires the introduction of a DLL (you can select the. net2.0 or. net4.0 dll), and then add references to the Web site.

2. Reference the namespace using Npoi. Ss. Usermodel

3. (For example, export Excel here) We need to understand what part of a complete Excel file is made up of!

(1) A workbook book, a worksheet sheet, and then include row rows, column columns, cell cells

4.

Create each part separately
Npoi. HSSF. Usermodel.hssfworkbook book = new Npoi. HSSF. Usermodel.hssfworkbook ();//npoi. Ss. Usermodel.isheet sheet = Book. Createsheet ("" "+ Type +" "to report rate statistics"); Npoi. Ss. Usermodel.irow row = sheet. CreateRow (0);

Set the style of an Excel file

Npoi. Ss. Usermodel.icellstyle style = Book . Createcellstyle (); style. Alignment = Horizontalalignment.center;style. Fillbackgroundcolor = Npoi. HSSF. Util.HSSFColor.DarkBlue.Index;
Style. Fillforegroundcolor = Npoi. HSSF. Util.HSSFColor.DarkBlue.Index;
