防止ASP.Net JSON在十進制屬性中丟棄尾隨0

Question

我正在使用內置的ASP.Net return JSON()函數將視圖模型轉換為JSON，在此視圖模型中，屬性之一是decimal 。 當此屬性填充有4.50或4.00類的值時，我注意到JSON版本的視圖模型將刪除尾隨的0（s）。 如何停止這種行為，以便在View的JavaScript中讀取數據時得到全0？

ViewModel：

public class TimeCardEntryVM
{
    public int ID { get; set; }
    public string ProjectCode { get; set; }
    public string ProjectDescription { get; set; }
    public string TaskCode { get; set; }
    public string TaskDescription { get; set; }
    public bool IsDurationTime { get; set; }
    public decimal HoursWorked { get; set; }
    public DateTime StartTime { get; set; }
    public DateTime EndTime { get; set; }
    public string WorkDescription { get; set; }
}

返回JSON的ASP.Net代碼：

{
    var timeEntryData = db.TimeCards
                            .Include(timeCard => timeCard.Project)
                            .Include(timeCard => timeCard.Task)
                            .Where(timeCard => timeCard.ID == timeCardID)
                            .Select(timeCard => new TimeCardEntryVM()
                            {
                                ID = timeCard.ID,
                                EndTime = timeCard.EndDateTime,
                                ProjectCode = timeCard.Project.Code,
                                ProjectDescription = timeCard.Project.Description,
                                StartTime = timeCard.StartDateTime,
                                TaskCode = timeCard.Task.Code,
                                TaskDescription = timeCard.Task.Description,
                                HoursWorked = (decimal)timeCard.TimeWorked,
                                IsDurationTime = timeCard.IsDurationTime,
                                WorkDescription = timeCard.WorkDescription
                            }).First();

    return Json(timeEntryData, JsonRequestBehavior.AllowGet);
}

我用來檢查值的JavaScript代碼：

$.ajax({
    type: "POST",
    url: "/TimeCard/TimeCardEntry",
    data: { timeCardID: args.row["uid"] },
    success: function (data)
    {
        alert(data["HoursWorked"]);
    }
});

為什么不只使用.toFixed（）在JavaScript中格式化結果：

$.ajax({
    type: "POST",
    url: "/TimeCard/TimeCardEntry",
    data: { timeCardID: args.row["uid"] },
    success: function (data)
    {
        var formattedHours = data.HoursWorked.toFixed(2);
    }
});
