使用Aspose插件对Excel操作

使用使用Aspose插件对Excel文档进行导入导出操作

使用前请先下载Aspose插件引用

Excel导入：

前台使用file标签获取，submit方式提交。

<form id="form1" enctype="multipart/form-data" method="post" >
 <table class="table-condensed">
<tr>
                    <td class="text-right">导入表格：</td>
                    <td class="text-left"><input type="file" name="file1" class="btn btn-default btn-lg" /></td>
</tr>
<tr>
                    <td class="text-left">
                        <input type="submit" id="btnImport" name="btnImport" value="导入" class="btn btn-default" />
                    </td>
                </tr>
</table>

</form>

后台接收：

HttpPostedFileBase fileBase = Request.Files["file1"];//这里获取名称与前台标签name保持一致
if (fileBase != null)
            {
                string filename = Path.GetFileName(fileBase.FileName);
                string extension = Path.GetExtension(filename);
                string path = "/Upload/Test/" + DateTime.Now.ToString("yyyyMMdd") + "/";
                Directory.CreateDirectory(Path.GetDirectoryName(Request.MapPath(path)));
                string newFilename = DateTime.Now.ToString("yyyyMMddHHmmssfff");
                string fullFileName = path + newFilename + extension;
                fileBase.SaveAs(Request.MapPath(fullFileName));
　　　　　　　　　 try
                {
　　　　　　　　　　　 Stopwatch sw = new Stopwatch();//记录导入操作用时多长
                    sw.Start();
//这里可放入BLL方法处理
string result = new ProductBLL().ImportExcel(Request.MapPath(path), newFilename, extension);

//BLL方法 ProductBLL
public string ImportExcel(string path, string filename, string extension)
        {
            Workbook workbook = new Workbook(path + filename + extension);
            Worksheet worksheet = workbook.Worksheets[0];
            Cells cells = worksheet.Cells;
            for (int i = 1; i < cells.Rows.Count; i++)

                }
                catch (Exception e)
                {
                    continue;
                }

            }
            return "OK";
        }

　　　　　　　　sw.Stop();
              long runTime = sw.ElapsedMilliseconds / 1000; //获取到操作用时多少秒
　　　　　　}
　　　　　　catch (Exception e)
