MVC3 下载个人档案
原标题:MVC3 Downloading individual files

我有MVC3C#.Net网络数据。 我们有一个“配对”特征。 用户上载了他们希望“Attach”提交提案的文件。 该文件储存在我们服务器上,等待下载。 这部分工作正在进行。

用户然后在表格中标出的“Attachment”的名称上点击。 我相信,这样做有共同的方法。 我不知道如何。 我如何用超链接下载档案?

最佳回答

为了下载超链接文件,你首先需要把文件名称作为行动路线价值。

@Html.ActionLink("Download", "Download", 
                 new { fileName = Model.AttachmentFileName })

页: 1 NET MVC 建造于 文件:

public ActionResult Download(string fileName)
{
    try
    {
        var fs = System.IO.File.OpenRead(Server.MapPath("/some/path/" + fileName));
        return File(fs, "application/zip", fileName);
    }
    catch
    {
        throw new HttpException(404, "Couldn t find " + fileName);
    }
}

<代码>申请/代码参数是指您重新返回的监评类型。 在本案中,它有案卷。
