我正在尝试获取一个 .csv 文件,其中包含一些由 jlst 对象过滤的数据(其中包含一些下拉框的选定 ID)。这是ajax调用:

        $('#moduleCSVReport').click(function () {

        $('#progress').show();
        $.ajax({
            url: '/Reports/GetPageAccessLevelsCSV?obj=' + jlst,
            dataType: "json",
            type: "GET",
            success: function (data) {
                $('#progress').hide();
            }
        });
    });

这是功能:

    public ActionResult GetPageAccessLevelsCSV(string obj)
    {
        JavaScriptSerializer jss = new JavaScriptSerializer();
        ReportsSelectedItems cParams = jss.Deserialize<ReportsSelectedItems>(obj);

        var locationIdFilter = (cParams.LocationId != 0) ? cParams.LocationId : 0;
        var divisionIdFilter = (cParams.DivisionId != 0) ? cParams.DivisionId : 0;

        IList<UserProfile> userProfiles = new List<UserProfile>();
        userProfiles = Session.Query<UserProfile>().Where(n => n.Employee != null && ((n.Employee.Division.Id == cParams.DivisionId || cParams.DivisionId == 0) && (n.Employee.Location.Id == cParams.LocationId || cParams.LocationId == 0))).OrderBy(n => n.Employee.Name).ToList();

        MemoryStream output = new MemoryStream();
        StreamWriter writer = new StreamWriter(output, Encoding.UTF8);

        writer.Write("Name,");
        writer.Write("Team");

        foreach(UserProfile user in userProfiles)
        {
            writer.Write(user.Employee.Name);
            writer.Write(",");
            writer.Write(HasAccessToModule((int)ModuleEnum.Team, user.Id).ToString());
            writer.WriteLine();
        }

        writer.Flush();
        output.Position = 0;

        return File(output, "application/x-ms-excel", "test.csv");
    }

我正在跟踪断点,文件似乎已成功生成。只是我在ajax调用中接收到文件后不知道如何显示。我认为必须有一种方法来处理文件(可能在成功事件中)。如果是这样,我该怎么做?谢谢。
