Aspose.Excel.dll Excel导入、导出

第一步：引用：Aspose.Excel.dll

第二步：创建类文件AsposeExcel

代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Aspose.Excel.Cells;
using System.Data;
using System.Windows;
using System.Windows.Forms;
using System.IO;
namespace BIM.Backend.Modules
{
    class AsposeExcel
    {

        private string outFileName = "";
        private string fullFilename = "";
        private Workbook book = null;
        private Worksheet sheet = null;



        #region //导入构造数
        public AsposeExcel(string fullfilename)
        {
            fullFilename = fullfilename;
            // book = new Workbook();
            //book.Open(tempfilename);
            //sheet = book.Worksheets[0];
        }
        #endregion     


        #region 导入方法
        public DataTable ExcelToDatatalbe()
        {
            Workbook book = new Workbook();
            book.Open(fullFilename);
            Worksheet sheet = book.Worksheets[];
            Cells cells = sheet.Cells;
            //获取excel中的数据保存到一个datatable中
            DataTable dt_Import = cells.ExportDataTableAsString(, , cells.MaxDataRow + , cells.MaxDataColumn + , false);
            // dt_Import.
            return dt_Import;
        }
        #endregion



    }
}
           

导入事件代码：
