如何遍历两个日期范围并在ASP.NET日历中显示？ [英] How to iterate through two date ranges and display in ASP.NET Calendar?

问题描述

我正在尝试创建一个酒店预订日历，选择 DateFrom 和 DateTo



我需要从 DateFrom 迭代到 DateTo 并显示所有这些日历中的日期，我到目前为止的代码只选择`DateFrom`和`DateTo`并将其作为标签显示在日历中：

I am trying to create a hotel booking calendar that selects the DateFrom and DateTo

I need to iterate through from the DateFrom to DateTo and display all these dates in the calendar, the code I have so far only selects the `DateFrom` and `DateTo` and displays them in the calendar as a label:

protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
   {
       foreach (DataRow dr in ds.Tables[0].Rows)
       {
           DateTime df = (DateTime)dr.Field<DateTime?>("DateFrom");
           DateTime dt = (DateTime)dr.Field<DateTime?>("DateTo");


           if (e.Day.Date == dt.Date)
           {
               Label lbl = new Label();
               lbl.BackColor = System.Drawing.Color.Gray;
               lbl.Text = "Booked From";
               e.Cell.Controls.Add(lbl);
            }

           if (e.Day.Date == df.Date)
           {
               Label lbl = new Label();
               lbl.BackColor = System.Drawing.Color.Gray;
               lbl.Text = "Booked To";
               e.Cell.Controls.Add(lbl);
           }
       }

推荐答案

我正在使用的解决方案，以防有需要的人来其中包括：

The solution I am using in case somebody who needs this comes across this is:

protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{
  foreach (DataRow dr in ds.Tables[0].Rows)
  {
    DateTime df = (DateTime)dr.Field<DateTime?>("DateFrom");
    DateTime dt = (DateTime)dr.Field<DateTime?>("DateTo");

    if (e.Day.Date == dt.Date)
    {
        Label lbl = new Label();
        lbl.BackColor = System.Drawing.Color.Gray;
        lbl.Text = "Booked From";
        e.Cell.Controls.Add(lbl);
     }

    if (e.Day.Date == df.Date)
    {
        Label lbl = new Label();
        lbl.BackColor = System.Drawing.Color.Gray;
        lbl.Text = "Booked To";
        e.Cell.Controls.Add(lbl);
    }

    //Added Code
    if(e.Day.Date > df.Date && e.Day.Date < dt.Date)
    {
        Label lbl = new Label();
        lbl.BackColor = System.Drawing.Color.Gray;
        lbl.Text = "Day inbetween";
        e.Cell.Controls.Add(lbl);
    }
}
