(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：

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：

private static void Export<T>(IEnumerable<T> data, HttpResponse response)        {            Workbook workbook = new Workbook();            Worksheet sheet = (Worksheet)workbook.Worksheets[0];                                    PropertyInfo[] ps = typeof(T).GetProperties();            var colIndex = "A";            foreach (var p in ps)            {                                    sheet.Cells[colIndex + 1].PutValue(p.Name);                    int i = 2;                    foreach (var d in data)                    {                        sheet.Cells[colIndex + i].PutValue(p.GetValue(d, null));                        i++;                    }                    colIndex = ((char)(colIndex[0] + 1)).ToString();            }            response.Clear();            response.Buffer = true;            response.Charset = "utf-8";            response.AppendHeader("Content-Disposition", "attachment;filename=xxx.xls");            response.ContentEncoding = System.Text.Encoding.UTF8;            response.ContentType = "application/ms-excel";            response.BinaryWrite(workbook.SaveToStream().ToArray());            response.End();        }

 

非常简单，好用！
