Question

我有一个javascript函数，我需要调用一个控制器动作来将文件流返回给UI。我没有打开，保存并另存为对话框。在cshtml文件中，我有以下功能：DownloadFile

var selectUrl = '@Url.Action("Download", "Controller")' + "/" + filedetails; 
$.post(selectUrl);

在控制器中我有以下代码：

public ActionResult Download(string id)
return File(downloadStream, "application/octet-stream",fileName);

请告诉我这是正确的打电话方式。

尝试这种方式：ActionResult

 public ActionResult Download(string id) 
    {
          var cd = new System.Net.Mime.ContentDisposition
                    {

                        FileName = "imagefilename",
                        Inline = false,
                    };
        Response.AppendHeader("Content-Disposition", cd.ToString());
        string contentType = "application/octet-stream";
          // you are downloadStream
        return File(downloadStream, contentType);
    }
