如何将filecontentResult传递给视图

Question

我向我的控制器发送3个项目，＆＃34;从＆＃34;，＆＃34;到＆＃34;，＆＃34; StudentID＆＃34; ..

我收到了LinQ，我希望将此结果作为CSV文件传递给浏览器进行下载，但我不知道在我的视图中要写什么来获得此结果，

这是我的控制器：

public FileContentResult DownloadFile(String from,String to,int  StudentID)
{
    var myResult = (from t in db.students
                    where( t.date>=from && t.date<=to ) && t.studentID==StudentID
                    select new student {
                      stName = t.name,
                      st.fname = t.name
                    }).toList();
    var st = DataTag.NoExlusion;

    var csvByte = ASCIIEncoding
                    .ACII
                    .GetBytes( CSVexport.getCsv(myResult.toList(),st );

    return this.File(csvByte,"text/csv",".csv");
}

我的观点

            var data = { "StudentID": id, "from": frm_, "to": to_ };
   $.ajax({

                                    dataType: "json",
                                    type: "POST",
                                    url: "@Url.Action("DownloadFile", "Students")",
                                     contentType: "application/json;charset=utf-8",



                                        data: JSON.stringify(data),
                                          success: function (result) {


                        }
                        })
