(C#)利用Aspose.Cells组件导入导出excel文件

Aspose.Cells组件可以不依赖excel来导入导出excel文件：

导入：

[csharp] view plain copy

print?

1. public static System.Data.DataTable ReadExcel(String strFileName)  
2.         {  
3.             Workbook book = new Workbook();  
4.             book.Open(strFileName);  
5.             Worksheet sheet = book.Worksheets[0];  
6.             Cells cells = sheet.Cells;  
7.               
8.             return cells.ExportDataTableAsString(0, 0, cells.MaxDataRow + 1, cells.MaxDataColumn + 1, true);  
9.         }        

public static System.Data.DataTable ReadExcel(String strFileName)
        {
            Workbook book = new Workbook();
            book.Open(strFileName);
            Worksheet sheet = book.Worksheets[0];
            Cells cells = sheet.Cells;
            
            return cells.ExportDataTableAsString(0, 0, cells.MaxDataRow + 1, cells.MaxDataColumn + 1, true);
        }      

导出：

[csharp] view plain copy
