使用Microsoft.Office.Interop.Excel.dll刷新页面创建和导出Excel

Question

服务器具有Microsoft Office 2003.代码如下

在aspx页面

<asp:UpdatePanel ID="UpdatePanel2" runat="server">
  <ContentTemplate>
    <asp:LinkButton ID="ExportExcel" runat="server" OnClick="ExportTabletoExcel_Click" OnClientClick="ExportTableJqueryMethod">ExportExcel</asp:LinkButton>
 </ContentTemplate>
  <Triggers>
    <asp:PostBackTrigger ControlID="ExportExcel" />
  </Triggers>
</asp:UpdatePanel>

在Code背后

using Excel1= Microsoft.Office.Interop.Excel;
...
protected void ExportTabletoExcel_Click(object sender, EventArgs e)
{
Excel1.Application excelApp = new Excel1.Application();
...//Adding Data to Excel
excelWorkBook.SaveAs(path, Excel1.XlFileFormat.xlWorkbookNormal);
excelWorkBook.Close();

...//to download
HttpContext.Current.Response.ContentType = "application/xls";
HttpContext.Current.Response.AppendHeader("content-disposition", "attachment; > filename=ExportedExcel.xls");
HttpContext.Current.Response.WriteFile(path + ".xls");
}

在Web.config中<add assembly="Microsoft.Office.Interop.Excel, Version=11.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c"/>

点击Visual Studio，excel下载就好了。但是在服务器上运行相同内容时刷新页面并且没有excel下载。

不确定，但你应该通过转到你的应用程序池检查你的服务器IIS Pool到Enable 32-bit Applications。右键单击并转到“高级”设置。

见下图，

应该是真的。

我的代码如下所示：

1. 在excel工作簿中创建多个工作表;
2. 将excel保存到Web服务器中的临时位置;
3. 并从Web应用程序下载excel文件。

使用System.Web.UI.WebControls;使用Excel = Microsoft.Office.Interop.Excel; ......私有Excel.Workbook GenerateExcel（）{string excelFileName = HttpContext.Current.Server.MapPath（“〜/ App_Data / TestFile.xlsx”）; Excel.Application excel = null; Excel.Workbook excelworkBook = null;试试{excel = new Excel.Application（）; excel.Visible = false; excel.DisplayAlerts = false;

            //create two sheets AAA & BBB
            excelworkBook = excel.Workbooks.Add();
            Excel.Worksheet excelSheet1 = (Excel.Worksheet)excelworkBook.ActiveSheet;
            excelSheet1.Name = "AAA";
            Excel.Worksheet excelSheet2 = (Excel.Worksheet)excelworkBook.Worksheets.Add();
            excelSheet2.Name = "BBB";

            DataTable dataTable = GetTable();

            // now we resize the columns
            Excel.Range excelCellrange1 = excelSheet1.Range[excelSheet1.Cells[1, 1], excelSheet1.Cells[dataTable.Rows.Count, dataTable.Columns.Count]];
            excelCellrange1.EntireColumn.AutoFit();

            //Now fill excelSheet1 up with data
            int row = 1;
            int col = 1;
            foreach (DataRow r in dataTable.Rows)
            {
                for (int j = 0; j < dataTable.Columns.Count; j++ )
                {
                    excelSheet1.Cells[row, col] = r[j];
                    col++;
                }
                row++;
            }

            //Now fill excelSheet2
            row = 1;
            col = 1;
            foreach (DataRow r in dataTable.Rows)
            {
                for (int j = 0; j < dataTable.Columns.Count; j++)
                {
                    excelSheet2.Cells[row, col] = r[j];
                    col++;
                }
                row++;
            }
        }
        catch (System.Exception ex)
        {
        }
        finally
        {
            excelworkBook.SaveAs(excelFileName);
            excel.Quit();
            excel = null;
            excelworkBook = null;
            FileInfo file = new FileInfo(excelFileName);
            if (file.Exists)
            {
                Response.Clear();
                Response.AppendHeader("Content-Disposition", "attachment; filename=" + file.Name);
                Response.AddHeader("Content-Length", file.Length.ToString());
                Response.TransmitFile(file.FullName);
                Response.Flush();
                Response.End();
            }

        }
        return excelworkBook;
    }
