查找两个日期之间的数据取决于当前日期 [英] To find data between two dates depend current date

问题描述

亲爱的所有人，

现在我想根据当前日期查找两个日期之间的一些数据.例如，在我的数据库中，我存储的一月(从)到三月(到)是冬天(季节)，三月到六月是夏天，六月到九月是寒冷.现在我有一个dateTimepicker和一个组合框.如果选择7月18日表示是，夏季在组合框中显示，而2月15日则表示它是冬季等.欢迎您这样做.欢迎所有答复...


谢谢&问候

解决方案

在C#中，日历选择更改了事件
，请检查所选的日期范围，然后在下拉列表中选择值

如果(Calendar1.SelectedDate.Month> =  1 && Calendar1.SelectedDate.Month< = " ;
 else 如果(Calendar1.SelectedDate.Month> =  4 && Calendar1.SelectedDate.Month< =  6 )
dropdownlist.SelectedValue = " 
 else 如果(Calendar1.SelectedDate.Month& ==  7 && amp; Calendar1 .SelectedDate.Month& lt; =  9 )
dropdownlist.SelectedValue = "  

更新的解决方案:
因此，您的意思是说您将决定日期和季节.因此，有一个包含3列SeasonName，StartDate，EndDate的表.然后，每当您在日历中选择一个值时，都从该表中查询名称.

 选择 seasonName 来自 tbl 其中  @ dt  开始日期之间和结束日期

试试这个

 //  txt_date是文本框，您可以在其中从datatimepicker获取值
// 此处名为txt_date的文本框中的输入为"mm/dd/yyyy"格式
字符串 [] date = txt_date.Text.Split('  /');
字符串 month = dd [ 0 ].ToString();
字符串 date = dd [ 1 ].ToString();
字符串 year = dd [ 2 ].ToString();
 int  m = Convert.ToInt32(month); 

现在您可以获得月份，现在根据月份获得您的季节；

如果(m> =  1  || m< =  3 )
dropdownlist.SelectedValue = " ;
其他如果(m> =  4  || m => 6)
dropdownlist.SelectedValue = " ;
其他如果(m> =  7  || m< =  9 )
dropdownlist.SelectedValue = " ;

解决方案

in c#, calendar selectionchanged event
, check the selected date range and select the value in dropdown

If (Calendar1.SelectedDate.Month>=1 &&Calendar1.SelectedDate.Month<=3)
dropdownlist.SelectedValue="Winter";
else If (Calendar1.SelectedDate.Month>=4 &&Calendar1.SelectedDate.Month<=6)
dropdownlist.SelectedValue="Summer"
else If (Calendar1.SelectedDate.Month&gt;=7 &amp;&amp;Calendar1.SelectedDate.Month&lt;=9)
dropdownlist.SelectedValue="Cold"

Updated solution:
So you meant to say you will decide the date and the season. So have a table with 3 columns SeasonName, StartDate, EndDate. Then whenever you select a value in calendar, query the name from this table.

Select seasonName from tbl where @dt between startdate and Enddate

Try this one

//txt_date is textbox in which  you get the value from datatimepicker
//here the input in textbox named txt_date is in "mm/dd/yyyy" format
string[] date = txt_date.Text.Split('/');
string month = dd[0].ToString();
string date = dd[1].ToString();
string year = dd[2].ToString();
int m = Convert.ToInt32(month);

Now you get the month, Now get your season according to month;

If (m>=1 || m<=3)
dropdownlist.SelectedValue="Winter";
else If (m>=4 || m=>6)
dropdownlist.SelectedValue="Summer";
else If (m>=7 || m<=9)
dropdownlist.SelectedValue="Cold";
