导出到Excel在某些机器上失败
我们正在开发一个Web应用程序，我们的一些查询结果需要导出到Excel。 我们正在使用下面的C＃代码来导出：
System.Web.HttpContext ctx = System.Web.HttpContext.Current; CurrentPackingListModel.Voyage.ShipmentDataContext = ShipmentDataContext; ctx.Response.Clear(); string filename = "ApprovalForm.xls"; ctx.Response.AddHeader("content-disposition", "attachment;filename=" + filename); ctx.Response.ContentType = "application/vnd.ms-excel"; ctx.Response.ContentEncoding = System.Text.Encoding.GetEncoding("UTF-8"); ctx.Response.Charset = "UTF-8"; return View("../Packing/_ExportApprovalForm", CurrentPackingListModel); 我返回结果的部分视图如下：
<body id="body" onload="window.print();"> <table> <tbody> <tr> <td class="table-header" colspan="8"> <div style="width: 100%"> <div class="lleft"> @* <img id="imgLogo" src="~/Images/myLogo.png" />*@ </div> <div class="baslik">Approval Packing List Form</div> <div style="float: right;">@DateTime.Now.ToString("MM.dd.yyyy")</div> </div> </td> </tr> <tr> <td colspan="6"></td> </tr> <tr> <td></td> </tr> <tr> <td></td> </tr> <tr> <td class="line-header">@Html.DisplayNameFor(x => x.ID)</td> <td>: @Html.HiddenFor(x => x.ID)@Html.DisplayFor(x => x.ID)</td> <td class="line-header" style="width: 165px;">@Html.DisplayNameFor(x => x.Voyage.StartDate)</td> <td>: @Html.DisplayFor(x => x.Voyage.StartDate)</td> <td class="line-header">@Html.DisplayNameFor(x => x.Voyage.VesselID)</td> <td>: @Html.DisplayFor(x => x.Voyage.VesselText) </td> </tr> <tr> <td class="line-header">@Html.DisplayNameFor(x => x.Voyage.Id)</td> <td>: @Html.DisplayFor(x => x.Voyage.Id)</td> <td class="line-header" style="width: 165px;">@Html.DisplayNameFor(x => x.Voyage.EndDate)</td> <td>: @Html.DisplayFor(x => x.Voyage.EndDate)</td> <td></td> <td></td> </tr> <tr> <td colspan="6"> <hr /> </td> </tr> </tbody> </table> <table> <tr> <td class="line-header" style="width: 160px;">Approve Personel</td> <td style="border: solid 1px; width: 180px;"></td> <td class="line-header">Discharge Port</td> <td style="border: solid 1px; width: 180px;"></td> </tr> <tr> <td class="line-header">Approve Date</td> <td style="border: solid 1px;"></td> <td class="line-header">Terminal</td> <td style="border: solid 1px;"></td> </tr> <tr> <td class="line-header">Signiture</td> <td style="border: solid 1px;"></td> <td></td> <td></td> </tr> </table> @if (Request.QueryString["type"] == "HRC" && Model.HrcListPrint != null) { <table> <tr> <td colspan="10" style="height: 20px;"> <hr /> </td> </tr> <tr> <td style="text-align: center; width: 210mm; font-weight: bold;" colspan="11">HRC LIST </td> </tr> </table> <table class="display dataTable no-footer"> <thead> <tr> <th>Customer Name</th> <th>Customer PO No</th> <th>Ord.

但是导出到Excel可以在一些机器上运行，但是不能用于其他机器 这只是最近才开始发生的。
有没有可能的解决scheme来解决这个问题，而不重写整个导出function？
道歉这不是一个答案，但我无法评论，因为我有低代表。
是不是在工作的机器上安装了Excel excel？ 从我的记忆中，必须安装excel才能导出。 过去我用Epplus来解决这个问题。
你能够添加一些exception处理和logging这个发布，所以你可以从错误中获得更多的细节？ 即使您只是将其写入机器上的txt文件。
对不起，我没有任何实际的答案。
下面的代码可能会对你有所帮助：
public void ExportToExcel() { DataGrid dgGrid = new DataGrid(); dgGrid.DataSource = /*Give your data source here*/; dgGrid.DataBind(); System.Web.HttpContext.Current.Response.ClearContent(); System.Web.HttpContext.Current.Response.Buffer = true; System.Web.HttpContext.Current.Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", "Data Report.xls")); System.Web.HttpContext.Current.Response.ContentType = "application/vnd.ms-excel"; System.Web.HttpContext.Current.Response.Charset = ""; System.IO.StringWriter sw = new System.IO.StringWriter(); HtmlTextWriter htw = new HtmlTextWriter(sw); dgGrid.RenderControl(htw); System.Web.HttpContext.Current.Response.Output.Write(sw.ToString()); System.Web.HttpContext.Current.Response.Flush(); System.Web.HttpContext.Current.Response.End(); }
