如何在asp.net中增加和减少日期

Question

如何在asp.net中增加和减少日期..

我尝试过以下代码..

或者有没有像javascript一样的替代品？？

    {
      string dt;
    protected void Page_Load(object sender, EventArgs e)
    {
        dt = DateTime.Now.ToShortDateString().ToString();
        date.Text = dt;
    }

    protected void decr_Click(object sender, EventArgs e)
    {
        date.Text = Convert.ToDateTime(date.Text).AddDays(-1).ToShortDateString().ToString();         
    }

    protected void incr_Click(object sender, EventArgs e)
    {
        date.Text =Convert.ToDateTime(date.Text).AddDays(1).ToShortDateString().ToString();          
    }

Answer 1

在Page_Load

中包含if (!Page.IsPostBack)事件的代码

 protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack)
            {
                dt = DateTime.Now.ToShortDateString().ToString();
                date.Text = dt;
            }
        }
