C#中实现插入、删除Excel分页符的方法

using Spire.Xls;

namespace ExcelPageBreak_XLS
{
 class Program
 {
 static void Main(string[] args)
 {
 //实例化一个Wordbook类对象，并加载需要设置分页的Excel文档
 Workbook workbook = new Workbook();
 workbook.LoadFromFile("Sample.xlsx");

 //获取第一个工作表
 Worksheet sheet = workbook.Worksheets[0];

 //插入两个横向分页符(指定单元格上方插入分页)
 sheet.HPageBreaks.Add(sheet.Range["A11"]);
 sheet.HPageBreaks.Add(sheet.Range["A20"]);

 //插入一个纵向分页符（指定单元格左侧插入分页）
 //sheet.VPageBreaks.Add(sheet.Range["E1"]);

 //将视图设置为分页预览模式查看效果
 sheet.ViewMode = ViewMode.Preview;

 //保存并打开文档
 workbook.SaveToFile("AddPageBreak.xlsx", FileFormat.Version2010);
 System.Diagnostics.Process.Start("AddPageBreak.xlsx");
 }
 }
}

using Spire.Xls;
namespace DeletePageBreak_XLS
{
 class Program
 {
 static void Main(string[] args)
 {
 //创建一个Workbook类对象，并加载Excel文档
 Workbook workbook = new Workbook();
 workbook.LoadFromFile("sample.xlsx");

 //获取第一个worksheet
 Worksheet sheet = workbook.Worksheets[0];
 
 //删除所有横向分页
 sheet.HPageBreaks.Clear();

 //删除第一个横向分页
 //sheet.HPageBreaks.RemoveAt(0);

 //设置分页预览模式查看分页效果
 sheet.ViewMode = ViewMode.Preview;

 //保存并打开文档
 workbook.SaveToFile("删除分页1.xlsx",FileFormat.Version2010);
 System.Diagnostics.Process.Start("删除分页1.xlsx");
 }
 }
}
