我该如何更改日期？对于日历

Question

我有一个日历，我需要一个按钮来更改月份，我要做的基本上是当您更改操作系统的日期时，它也更改了日历，我得到了我只需要的工作一个按钮，我不知道该怎么做或从哪里开始。

@ 这是我的观点，我认为不需要显示模型和控制器 @

    int currentMonth = DateTime.UtcNow.Month;
    int currentYear = DateTime.UtcNow.Year;
    DateTime firstDay = new DateTime(DateTime.UtcNow.Year, DateTime.UtcNow.Month, 1);
    DateTime lastDay = new DateTime(currentYear, currentMonth, Model.DaysOfMonth.Count);
    int dayOfWeekFirst = ((int)firstDay.DayOfWeek > 0) ? (int)firstDay.DayOfWeek : 7;


<div class="col-sm-6 col-md-6 col-lg-6">
    <table class="table color-table info-table table-bordered">
        <thead>

            }
            <!-- filling up space of current month -->
            @for (int i = Model.DaysOfMonth[0].DayOfMonth; i <= Model.DaysOfMonth.Count; i++)
        {
            DateTime renderedDay = new DateTime(firstDay.Year, firstDay.Month, i);
