Question

我正在控制器中使用导出方法，使用此方法将表中的数据下载到excel文件中：这是索引文件中的表：

<table class="table">
    <tr>
        <th>
            @Html.DisplayNameFor(model => model.Name)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Marks)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Grade)
        </th>
        <th></th>
    </tr>

@foreach (var item in Model) {
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.Name)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Marks)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Grade)
        </td>
        <td>
            @Html.ActionLink("Edit", "Edit", new { id=item.id }) |
            @Html.ActionLink("Details", "Details", new { id=item.id }) |
            @Html.ActionLink("Delete", "Delete", new { id=item.id })
        </td>
    </tr>
}

</table>

并且在我的控制器中，我编写了此方法，当您在索引视图中按导出按钮时触发该方法：

 public ActionResult ExportData()
        {
            GridView gv = new GridView();
            gv.DataSource = db.Studentrecords.ToList();
            gv.DataBind();
            Response.ClearContent();
            Response.Buffer = true;
            Response.AddHeader("content-disposition", "attachment; filename=Marklist.xls");
            Response.ContentType = "application/ms-excel";
            Response.Charset = "";
            StringWriter sw = new StringWriter();
            HtmlTextWriter htw = new HtmlTextWriter(sw);
            gv.RenderControl(htw);
            Response.Output.Write(sw.ToString());
            Response.Flush();
            Response.End();

            return RedirectToAction("StudentDetails");
        }

一切正常，该表很容易下载到excel文件中，但是当我打开文件时，它在打开文件的开头给出了以下错误：文件格式不匹配。文件可能已损坏或不安全。问题的原因主要是因为文件以xls格式保存，而我想将其保存为xlxs格式，那怎么可能呢？

要将MVC视图数据导出到Excel文件中，我正在使用ClosedXml库。

public ActionResult ExportToExcel()
    {
        var gv = new GridView();
        gv.DataSource = this.GetEmployeeList();
        gv.DataBind();

        Response.ClearContent();
        Response.Buffer = true;
        Response.AddHeader("content-disposition", "attachment; filename=DemoExcel.xls");
        Response.ContentType = "application/ms-excel";

        Response.Charset = "";
        StringWriter objStringWriter = new StringWriter();
        HtmlTextWriter objHtmlTextWriter = new HtmlTextWriter(objStringWriter);

        gv.RenderControl(objHtmlTextWriter);

        Response.Output.Write(objStringWriter.ToString());
        Response.Flush();
        Response.End();

        return View("Index");

    }
