使用Aspose插件对Excel操作

Posted 2020-07-15 Tony

使用使用Aspose插件对Excel文档进行导入导出操作

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++)
            {
                try
                {
                    string brand = cells[i, 0].StringValue.Trim();//获取列值
                    string years = cells[i, 1].StringValue.Trim();
                }
                catch (Exception e)
                {
                    continue;
                }

            }
            return "OK";
        }

sw.Stop();
                    long runTime = sw.ElapsedMilliseconds / 1000;
}
catch (Exception e)
                {
                    Log.Write("导入", "导入错误", "错误信息：" + e.Message);
                }

           }

Excel导出：

string path = "/Upload/Test/" + DateTime.Now.ToString("yyyyMMdd") + "/";
            Directory.CreateDirectory(Path.GetDirectoryName(Server.MapPath(path)));
            string newFilename = DateTime.Now.ToString("yyyyMMddHHmmssfff") + ".xls";
            string fullFileName = Server.MapPath(path + newFilename);

public void ExportInfo(List<Test> list, string fullFileName)
        {
Aspose.Cells.Workbook workbook = new Aspose.Cells.Workbook();
            Aspose.Cells.Worksheet cellSheet = workbook.Worksheets[0];

            cellSheet.PageSetup.LeftMargin = 0.3;
            cellSheet.PageSetup.RightMargin = 0.3;
            cellSheet.PageSetup.TopMargin = 1;
            cellSheet.PageSetup.BottomMargin = 0.5;
            cellSheet.PageSetup.FooterMargin = 0.5;
            cellSheet.PageSetup.HeaderMargin = 0.5;
            cellSheet.PageSetup.Orientation = PageOrientationType.Landscape;
            cellSheet.PageSetup.CenterHorizontally = true;
            cellSheet.PageSetup.CenterVertically = true;

cellSheet.Cells[0, 0].PutValue("货号");
            cellSheet.Cells[0, 1].PutValue("颜色");
            cellSheet.Cells[0, 2].PutValue("尺码");

int i = 1;
            foreach (var item in list)
            {
cellSheet.Cells[i, 0].PutValue(item.productno);
                cellSheet.Cells[i, 1].PutValue(item.size);
                cellSheet.Cells[i, 2].PutValue(item.color);
i++;
            }
cellSheet.AutoFitColumns();

            fullFileName = Path.GetFullPath(fullFileName);
            workbook.Save(fullFileName);
}
