Параметры DateTime в MVC

Question

Я работаю над программой, в которой я отправляю переменную DateTime в сортируемый jQuery DataTable. Это конструктор в моем файле «Модель»:

public StudentDailyStatus(int studentID, DateTime startDate, DateTime endDate, string code, string status, int goodDays, int badDays, int leave, int lengthOfStay) 

А потом вот те ценности, которые я пытаюсь поместить в объект:

new StudentDailyStatus(1, (2015, 1, 1), (2015, 2, 1), "1","Normal","2",0,0,0), 

Моя ошибка будет: «[файл ] не содержит конструктор, который принимает 4 аргумента ".

Но у меня возникают проблемы с параметрами startDate и endDate. Как использовать переменные DateTime? Спасибо за помощь!

    } 

} 

Answer 1

Хорошо, если вы вводите даты, как это, (2015, 2, 1) то вы ошибаетесь ,

Вы должны передать ваши даты в качестве аргументов, как это ... new DateTime(2015, 2, 1)

Таким образом, это должен быть ваш вызов конструктора ...

new StudentDailyStatus(1, new DateTime(2015, 1, 1), new DateTime(2015, 2, 1), "1","Normal","2",0,0,0) 

Answer 2

Вы просто отправляете ("2015,01 ,. .. "), а не дату. Сначала необходимо создать объект dateTime, а затем отправить его в конструктор.

new Date(year, month, day, hours, minutes, seconds, milliseconds); 

Для дальнейшей контрольной проверки http://www.w3schools.com/jsref/jsref_obj_date.asp

Answer 3

(2015, 1, 1) не DateTime Значение ... использовать вместо new DateTime(2015, 1, 1)
