我有一个存储在类型变量中的值System.TimeSpan,如下所示.

System.TimeSpan storedTime = 03:00:00;

我可以将它重新存储在另一个类型的变量中String,如下所示吗？

String displayValue = "03:00 AM";

如果storedTime变量的值为

storedTime = 16:00:00;

那么它应该转换为:

String displayValue = "04:00 PM";

我想通过ajax请求返回记录

C#代码如下:

    [HttpPost]
    public WorkoutsViewModel GetSavedWorkoutTemplate(int WorkoutId)
    {
        return _db.Workouts.Where(w => w.Id == WorkoutId).Select(w => new WorkoutsViewModel
        {
            Tag = w.Tags.FirstOrDefault(),
            Name = w.Name,
            MaxEffort = w.MaxEffort,
            Id = w.Id,
            Description = w.Description,
            Compare = w.Compare,
            Category = w.Category
        }).FirstOrDefault();
    } 

jQuery代码是:

function GetSavedWorkoutTemplate(obj) {      
    $("#Workout").hide();
    var WorkoutId = $(obj).val();
    if (WorkoutId == "") {
        return;
    }
    var dto = { "WorkoutId": WorkoutId };

    $.ajax({
        type: "post",
        url: "/MemberWorkout/GetSavedWorkoutTemplate",
        contenttype: "application/json; charset=utf-8",
        data: dto,       
        success: function (result) {
            debugger;
            $("#Workout").show(); …

我有MySQL,查询是:

select name,re_type from myTable

我想替换所有类型的值:

1 = student
2 = teacher 

所以结果应该是:

name    re_type
---------------
Ron     Student
Mac     Teacher

不喜欢:

name    re_type
---------------
Ron     1
Mac     2

是否有可能进行这样的查询,以便在MySQL中获得所需的结果？
