Question

我正在尝试将列表对象从表中发布回控制器操作方法，以将数据导出为csv。

我尽了一切努力，但想不通，如果有人可以帮助我，我将不胜感激。

让我知道我是否在cshtml和action方法上做得正确。

@model List<RapidFinanceCodeBehindBusinessLogic.ViewModels.SharedViewModel>

@{
    ViewBag.Title = "GetCompaniesFromUploadedFile";
    //var modelOrdered = Model.OrderByDescending(m=>m.CompanyName);
}

<h2>Get Companies From Uploaded File</h2>

@using (Html.BeginForm("ExportCompaniesListToCSV", "Home"))
{
    <table class="table table-bordered">
        <thead>
            <tr>
                @*<th>
                        @Html.ActionLink(Model.OrderByDescending(x => x.CompanyName))
                    </th>*@
                <th><a>Company Name</a></th>
                <th><a>Years in Business</a></th>
                <th><a>Contact Name</a></th>
                <th><a>Contact Phone Number</a></th>
                <th><a>Contact Email</a></th>
            </tr>
        </thead>
        <tbody>
            @foreach (var item in Model)
            {
                <tr>
                    <td>@item.CompanyName</td>
                    <td>@item.YearsInBusiness</td>
                    <td>@item.ContactName</td>
                    <td>@item.ContactPhoneNumber</td>
                    <td>@item.ContactEmail</td>
                </tr>
            }
        </tbody>
    </table>
    <div class="form-group">
        <div class="col-md-offset-2 col-md-10">
            <input type="submit" value="Export to CSV" class="btn btn-success" />
        </div>
    </div>

}

 [HttpPost]
        public ActionResult ExportCompaniesListToCSV(FormCollection model)
        {            
            StringWriter sw = new StringWriter();
            sw.WriteLine("\"Company Name\",\"Years in Business\",\"Contact Name\",\"Contact Phone Number\",\"Contact Email\"");

            Response.ClearContent();
            Response.AddHeader("content-disposition", "attachment;filename=Exported_Users.csv");
            Response.ContentType = "text/csv";

            //foreach (var line in model)
            //{
            //    sw.WriteLine(string.Format("\"{0}\",\"{1}\",\"{2}\",\"{3}\"",
            //                               line.FirstName,
            //                               line.LastName,
            //                               line.Dob,
            //                               line.Email));
            //}

            Response.Write(sw.ToString());

            Response.End();
            return RedirectToAction("GetCompaniesFromUploadedFile");
        }

我不得不利用asp.net MVC概念，例如临时数据，视图数据，将数据从一个控制器动作传递到另一个控制器动作。整个想法不是使用javascript库和引导程序，因此使用临时数据和视图数据来实现此目的。感谢社区的所有支持。
