我遵循了这个指南,这是在另一篇文章中推荐的,但我无法让它工作.尝试重定向到/ LogModelsController/ExportData时出现404错误 - 正如我所理解的那样 - 是我本应该做的.

_LogPartialLayout.cshtml

@using (Html.BeginForm("ExportData", "LogModelsController", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    <table class="table">
        <tr>
            <th>
                @Html.ActionLink("message", "Index", new { sortOrder = ViewBag.NameSortParm, currentFilter = ViewBag.CurrentFilter })

            </th>
            <th>
                @Html.ActionLink("timestamp", "Index", new { sortOrder = ViewBag.NameSortParm, currentFilter = ViewBag.CurrentFilter })
            </th>
            <th>
                @Html.ActionLink("level", "Index", new { sortOrder = ViewBag.NameSortParm, currentFilter = ViewBag.CurrentFilter })
            </th>

        </tr>

        @foreach (var item in Model)
        {
            <tr>
                <td>
                    @Html.DisplayFor(modelItem => item.message)
                </td>
                <td>
                    @Html.DisplayFor(modelItem => item.timeStamp)
                </td> …

Excel告诉我有无法读取的数据,因此在我说尝试恢复信息后,它会显示正确的数据.但是当我打开xlsx的文本文件时,我得到整个页面的所有html,而不仅仅是gridview(这可能是Excel正在讨论的不可读的内容).

这是我的代码:

public void ExcelDownload(object sender, EventArgs e)
    {
        DataSet _MailingListUsers = db.GetMailingList();
        DataTable mailTable = _MailingListUsers.Tables[0];

        DumpExcel(mailTable);

    }

    private void DumpExcel(DataTable tbl)
    {
        using (ExcelPackage pck = new ExcelPackage())
        {
            //Create the worksheet
            ExcelWorksheet ws = pck.Workbook.Worksheets.Add("Mailing List");

            //Load the datatable into the sheet, starting from cell A1. Print the column names on row 1
            ws.Cells["A2"].LoadFromDataTable(tbl, false);

            //Header Titles
            ws.Cells["A1"].Value = "Employee Name";
            ws.Cells["B1"].Value = "Email Address";
            ws.Cells["C1"].Value = "Phone";
            ws.Cells["D1"].Value = "Business Unit";
            ws.Cells["E1"].Value = "Site";

            ws.Cells["A1"].AutoFitColumns();

            //Format …
