namespace NPOI
{
class Program
{
static void Main(string[] args)
{
//说明：HSSFWorkbook 用于创建  .xls
//      XSSFWorkbook 用于创建  .xlsx

//1.创建EXCEL中的Workbook
IWorkbook myHSSFworkbook = new HSSFWorkbook();
IWorkbook myXSSFworkbook = new XSSFWorkbook();

//2.创建Workbook中的Sheet
ISheet mysheetHSSF = myHSSFworkbook.CreateSheet("sheet1");
ISheet mysheetXSSF = myXSSFworkbook.CreateSheet("sheet1");

//3.创建Sheet中的Row
IRow rowHSSF = mysheetHSSF.CreateRow(0);
//SetCellValue有5个重载方法 bool、DateTime、double、string、IRichTextString(未演示)
rowHSSF.CreateCell(0).SetCellValue(true);
rowHSSF.CreateCell(1).SetCellValue(System.DateTime.Now);
rowHSSF.CreateCell(2).SetCellValue(9.32);
rowHSSF.CreateCell(3).SetCellValue("Hello World！");
//4.创建Row中的Cell并赋值
IRow rowXSSF = mysheetXSSF.CreateRow(0);
rowXSSF.CreateCell(0).SetCellValue(false);
rowXSSF.CreateCell(1).SetCellValue(System.DateTime.Now);
rowXSSF.CreateCell(2).SetCellValue(9.32);
rowXSSF.CreateCell(3).SetCellValue("Hello World！");

//5.保存
FileStream fileHSSF = new FileStream(@"E:\myHSSFworkbook.xls", FileMode.Create);
myHSSFworkbook.Write(fileHSSF);
fileHSSF.Close();

FileStream fileXSSF = new FileStream(@"E:\myXSSFworkbook.xlsx", FileMode.Create);
myXSSFworkbook.Write(fileXSSF);
fileXSSF.Close();
}
}
