将ISO8601字符串序列化为C＃TimeSpan

Question

My project is an ASP.Net MVC project. In JavaScript, I have an ISO 8601 string, like "PT15M" . How do I define my model so that it gets properly serialized to a TimeSpan object?

Here is my Javascript:

var model = new TemplateMapModel();
model.DelayBy = "PT15M";
if (PerformClientSideValidation(model)) {
    $.ajax({
        type: 'POST',
        url: '/api/TemplateMap',
        data: { templateMap: model, files: files },
        success: function (result) {
            $('#modalTemplateMap').modal('toggle');
        },
        error: function (xhr, textStatus, e) { 
            var error = xhr.responseJSON.Message;
            ShowMessageBox("Error", error);
            ToggleBusyIndicator(false);
        },
        complete: function (xhr, textStatus) {
            TEMPLATEMAPPING.grid.reload();
        }
    });
}

I tried this in my model:

public TimeSpan DelayBy { get; set; }

Doing this results in a null value. I also tried this:

public string DelayBy { get; set; }

This will work, and then I can use XmlConvert.ToTimeSpan() to get what I want, however, I would prefer not to do it this way because it doesn't seem like the correct way, having to declare my DelayBy as a string, then convert it in my business logic. I would like to use this definition:

public TimeSpan DelayBy { get; set; }

and have MVC automatically convert it to and from a TimeSpan object. Any ideas?

Try to define setter/getter

private TimeSpan _delayBy; 
public TimeSpan DelayBy { 
   get { 
      return this._delayBy;
   }
   set {
      this._delayBy = XmlConvert.ToTimeSpan(value.ToString());
   }
}
